GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 23 of 64 SECTION 4 VARIETAL CLASSIFICATION Barley classification is the categorisation of a barley variety into a grade based on malting qualities. The Classification Process aims to deliver grain of consistent physical quality, processing performance and end - product quality to customers and end - us ers. Barley Australia undertakes the management of malting barley variety classification. Where a load is delivered with a varietal mix that does not meet the minimum varietal purity of 95%, its maximum classification can only be Feed grade. The Barley Variety list below details all of the varieties acceptable for delivery into Malt , Food or Feed grades . Note that v arieties listed below may be governed by Plants Breeders Rights legislation : A. MALT Barley Accredited Varieties 2014/15 : Admiral Arapiles# Bass Baudin Buloke Commander Dhow# Fairview Fitzroy Flagship Gairdner GrangeR Grimmett# Hamelin Henley Macquarie Navigator Schooner Scope CL Sloop# Stirling Tallon# Vlamingh Westminster Wimmera The varieties listed in th e above table are A ccredited Australian malting barley varieties. These varieties may or may not be in demand by purchasers of malting barley, either domestically or internationally. C onsult the Preferred Varieties List on the Barley Australia website at http://www.barleyaustralia.com.au to see varieties that are currently preferred by purchasers of Australian malting barley. Note for v arieties marked with# : 1. These v arieties are now superseded in the marketplace by varieties with superior malting characteristics. 2. Whilst these varieties are still Accredited, there is now little demand or segregations for harvest receivals. 3. It is the opinion of Barley Australia that these varieties are no longer marketable.

GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 25 of 64 SECTION 5 METHODS & P ROCEDURES 5.1 Introduction The following section details methods and procedures to be used for the assessment of various quality parameters as outlined in this Manual. The methods outlined are either Reference Methods or Field Assessment Methods. Field Assessment Meth ods are included as a guide to industry where Reference Methods may not be able to be implemented. Note that Field Assessment Methods must equate to the Reference Method for the applicable test method. In all instances of disputes, test results produced by trade - certified equipment take precedence over non - trade certified equipment and methods. Where the dispute involves only non trade - certified equipment or test methods, the reference method takes precedence over the field assessment method . Depending on the test to be conducted, variations may exist due to equipment used. Procedures outlined are a guide for industry. Industry is free to develop their own Operational Procedures for each test and activity based on their own circumstances. At all times industry use of apparatus outlined in this Standard must comp l y with the manufacturers’ recommendations for occupational health and safety and train ing .

2. GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 2 of 64 S ECTION 1 INTRODUCTION General Since 1999 G rain T rade A ustralia (previously NACMA ) has on an annual basis reviewed, produced and published on behalf of to industry Barley Trading Standards (Standards) through its Standards Committee (Committee) . In order to provide a consistent message to both domestic industry and international buyers, GTA encourages input into development of these S tandards. Additionally, we urge industry to use the S tandards contained w ithin this Manual as applic able when buying and trading Australian barley . Considerations to the Standards This section of the Manual relating to Barl e y has been produced following the annual review by GTA of S tandards . There are various sections of this Manual relating to S tandards and associated procedures and industry is encourage d to take account of all relevant sections when applying these S tandards to barley bought and traded domestically or internationally . The Grades referred to in this document are a combination of : Grades commonly introduced across the country on an annual basis and are generally the same in each State where barley is grown or traded Grades that may not be introduced every season or only intro duced in a regional area . These grades may be created f or various reasons including to meet the specific quality requirements of a customer , as a specific varietal segregation or to deal with specific quality issues with harvested grain in a localised area Industry should note the list of Grades in this Manual is not exhaustive. Variations to Standards Whilst the information in this Manual is current at time of publication, you will need to monitor the GT A Member Updates , the GT A website ( www.graintrade.org.au ) and other applicable information to ensure that you are aware of the changes to the Standards and the impact on your own trading arrangements. Varieties Approved and recommended varieties to be grown and acceptable within each grade are listed within this document. The approval of each variety within a grade is determined by a group external to GT A. V ariety integrity and correct variety assessment is an integral part of the grain classification and S tandards application process . GT A endorses the varietal classifications as listed in this Manual and encourages all industry to follow the approved varietal list as listed in this Manual where relevant . Chang es to varietal classifications may occur at any time during the season following the publication of this Manual. As these changes will not necessarily be included in this Manual industry should implement their own procedures for monitor ing the varietal classification process. Timing of Standards Development The S tandards outlined in this Manual are applicable for the entire season of 20 1 4 /1 5 . Standards apply to grain assessed as per these Standards from 1 August 20 1 4 to 31 July 20 1 5 .
38. GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 38 of 64 Carefully tip the cylinder upside down and tip out all the grain remaining above the divider. Make sure to catch the weight D as it drops down. Place a plastic container on the electric balance and tare to read zero. Remove the blade from the chondrometer and tip the measured litre of grain into the plastic container and weigh. The weight is in grams and needs to be multiplied by 0 .1 (divided by 10) to obtain a density in kg/hl. Always undertake analysis in duplicate and average results. Report the result to one (1) decimal place. 5.8.6 References Test Weight Per Bushel - AACC Method 55 - 10 National Measurement Institute General Certificate of Approval No 4/10/0

31. GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 31 of 64 When one hour has elapsed, standardise the instrument by selecting the empty dish and placing 9g in weights in the small platform between the 3 pr ongs on the balance and adjust the scale to 10.0 with the standard swinging freely. Moisture can then be read off for each sample in turn. Read the samples in the dishes consecutively recording results in the relevant worksheet. NOTE: When switching the oven on make sure that the Brabender oven is level (use bubble level). All results are a direct reading of % w/w water . The minimum heating time must be adhered to (1 hour) but heating over the hour will not affect the results (up to 2 h ou rs). If o nly a few grams of sample are available see the manufacturers hand book for the technique to be adopted. The w eight of Aluminium dishes is to be checked at 6 monthly intervals to ensure they are within 11.500 +/ - 0.005g. If they are underweight they are t o be discarded and replacements purchased . D o not add weight to the dish i.e. solder etc as this will breakdown over time or fall off. If they are overweight they may be cleaned with warm water and neutral detergent . U nder no circumstances use abrasive or corrosive chemical s as this will lead to the dish being underweight. 5.4.6 References Moisture – Air Oven Methods – AACC Method 44 - 15A NMI M 8 Pattern Approval Specifications for Protein Measuring Instruments for Grain NMI V10 Uniform Test Procedures for the Verification, Certification and In Service Inspection of Protein Instruments for Grain
6. GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 6 of 64 This definition is to be read in conjunction with the photo in the Visual Recognition Standards Guide which depicts the mini mum affected standard for a grain to be classified as Dry Green or Sappy. Earth Earth is defined as a clod of dirt, being 5mm or less in diameter. Ergot Ergot is a purplish black fungal body, which contaminates cereal and ryegrass kernels when they are infected by the fungus Claviceps purpurea . Cereal Ergot Cereal ergot is Claviceps purpurea infection of any cereal kernels. A nil tolerance applies to any whole or pieces of affected kernels found in the sample. Ryegrass Ergot Ryegrass ergot is Claviceps purpurea infection of ryegrass kernels. Tolerances are defined in terms of overall length in cm when pieces found in the sample are aligned end on end . Falling Number Falling Number is a grain quality test which measures the degree of weather damage in barley and is based on the unique ability of alpha amylase (an enzyme released during seed germination) to liquefy a starch gel. Strength of the enzyme is measured by Falling Number defined as the time in seconds required to stir plus the time it takes to allow the stirrer to fall a measured distance through a hot aqueous flour or meal gel undergoing liquefaction. The Falling Number test is an alternative to the R apid V isco A nalyser (RVA) . Both the Falling Number and RVA results over - ride the visual assessment of Shot and/or Sprouted. F eed Grade Varieties to be accepted into the barley Feed Grade include: Those varieties not list ed as a M alt or Food variety ; and/or M alt or Food V arieties that do not meet the M alt or Food G rade specifications Refer to Varietal Classification in Section 4 for more information. Field Fungi Field Fungi refers to individual kernels where the seed coat has the appearance of black spotting occurring anywhere on the grain. Coverage greater than approximately 10% of the grain surface is considered defective. Grains that show approximately 10% or less of fungal growth are to be classified as sound. This def inition is to be read in conjunction with the photo in the Visual Recognition Standards Guide which depicts the minimum affected standard for a grain to be classified as Field Fungi. Food Grade The Food Grade is a grade of barley as defined within these Standards. The Food Grade is applicable to the barley variety Hindmarsh only. Hindmarsh will only be classified into the Food grade if it meets all Malt Grade specifications.
13. GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 13 of 64 As Pea Weevils are commonly found inside field pea seeds, it is recommended that a number of field peas present in a load of grain should be broken and assessed for the presence of this insect. Pickling Compounds or Artificial Colouring Pickling Compound s are those chemicals added to grain as a seed treatment or as a seed dressing prior to sowing. This includes grains that may be affected by marker dye commonly used during crop spraying operations that has stained the barley. They are usually associated w ith a colouring agent. Grains contaminated in this way may be identified by an unnatural surface colour and/or a colour that rubs off. Any grains that are artificially coloured regardless of intensity are defective. Protein Proteins (amino acids arranged in a linear chain) form a large component part of grains . T hese structures are responsible for the quality expressions in end use products made from barley . Rapid Visco Analyser (RVA) RVA is a grain quality test which measures the degree of pre harvest germination of malting barley and is based on the ability of the enzymes alpha amylase and (1 , 3 and 1,4) beta glucanase to be able to liquefy a starch gel. The strength of enzyme activity and therefore the degree of germination is measured by the RVA as defin e d by the force required to stir an aqueous barley meal mixture over a defined time period. The result of the RVA is a S tirring N umber . The RVA is an alternative to the Falling Number test. Both the RVA and Falling Number results over - ride t he visual assessment of Shot and/or Sprouted. Retention Retention is the material retained above the 2.5 0 mm screen after a sample of barley grain is subjected to the screening process. Sand A grain of sand is defined as a particle of unconsolidated (loose), rounded to angular rock fragment or mineral grain larger than 0.06mm that falls below the 2.2mm screen during the screening process. Smaller material is classified under Foreign Material. Material that is retained above the 2.2mm screen (includes material retained above the 2.5mm screen) is classified as Earth or Stones. Screenings See “ U nmillable M aterial below the S creen” . Shot Barley grains exhibiting the following outward signs of having commenced germination are classified as Shot: Open ing of the grain at the germ end ; and/or The husk has a distinct pin hole at the germ end or has ‘tramlines’ where the husk has begun to lift on each side on the back of the grain at the germ end. Note that the tramlines must be on both sides T he Falling Number or R apid V isco A nalyser result always over - rides the visual assessment of Shot. This definition is to be read in conjunction with the photo in the Visual Recognition Standards Guide which depicts the minimum affected standard for a grain to be clas sified as Shot.
16. GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 16 of 64 Unmillable Material b elow the Screen (Screenings) This is the total material passing through a 2. 2 0mm screen after a sample of grain is sub jected to the screening process . It includes S mall F oreign S eeds. Variety This is the next lowest level taxonomic rank of a plant below that of the term “species”. Barley varieties fall into two distinct grades , being Malt or Feed. Varietal Master List This list designates whether the barley variety’s highest classification can be a Malt grade , Food grade or a Feed grade. The variety’s grade is not dependent on its geographical growing region. The barley classifications are generally based on the following grades: Malt 1 Grade Malt 2 Grade Malt 3 Grade Food Grade Feed No. 1 Grade Feed No. 2 Grade Varietal Purity It is recognised that a load may not be 100% of a specific variety and may be contaminated by the presence of another variety of barley. Malting Barley is extremely sensitive to varietal admixtures. Different malting varieties cannot be binned together : All Malt grades are variety specific grades with a minimum varietal purity of 95% There are no varietal purity limits for Feed grades Specific limits apply to the presence of six row and blue / black aleurone varieties in barley grades. Visual Re cognition Standards Guide The Visual Recognition Standards Guide (VR S G) for Barley contains a range of photographs and illustrations to supplement the barley Standards as outlined in this booklet. The most recent VR S G for barley was released in August 201 4 . The Defective Grain definitions listed in this Standards Booklet are to be read in conjunction with the images dis played in the VRSG. The images in that document display the minimum and/or maximum coverage and attributes of the Defective Grain types as defined in these S tandards. Wheat, Cereal Rye, Triticale, C ultivated Oats , Rice These cereal grains are often referred to as Foreign Grain and are assessed separately from Foreign Seeds. W ild Oats , Wild Radish Wild Oats and Wild Radish are assessed separately from F oreign S eeds.

Repeat the jogging action if any lumps remain on the water surface or adhere to the paddle. Place the paddle into the canister and firmly insert the paddle into the RVA paddle coupling on the instrument. NO TE: The paddle must be fully inserted into the coupling (firmly squeeze the front of the paddle against the back of the coupling) for proper functioning of the instrument. Make sure that the paddle turns freely in the canister and does not rub against th e sides. If the paddle rubs it will give a higher than expected result. Initiate the measurement cycle by firmly depressing the blue motor tower of the instrument and immediately releasing it. On completion of the test, the tower will raise and the Stir ring N umber will be displayed at the front of the instrument. Record the Stirring number. NOTE: The instrument will display time in seconds for the duration of the three - minute test and then display the Stirring N umber at the completion of the test. Remove the canister with the insulating glove or tongs and discard. CAUTION: the sample canister is hot at the end of the test. 5.14.6 References American Association of Cereal Chemists Method – Weather Damage in grain: AACC 22 - 08, ICC 161 and Royal Australia n Chemical Institute Methos - RACI 05 - 05

GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 3 of 64 SECTION 2 DEFINITIONS The following Defect definitions are to be read in conjunction with the images displayed in the GTA Visual Recognition Standards Guide for Grain Commodity Sampling and Assessment located on the GTA website at www.graintrade.org.au . The images in that document display the minimum and/or maximum coverage and attributes of the Defect ive Grain type s as defined in these S tandards. As Is In terms of sample assessment, is the representative sample as taken from the load tendered for delivery without any interference to the sample. That is, there has been no cleaning or screening of the sample prior to analysis. The sample may a lso be referr ed to as a “dirty” sample. B arley Barley includes grains of the species Hordeum vulgare . Barley Not of the Current Season To be accepted into malt grades the load presented of approved malting varieties must be grown in the current season . Barley Not of the Current Season may be received into any Feed grade. Broken Refers to barley that is mechanically damaged due to the harvesting or handling process with a quarter or more of the grain missing . This includes any mechanical damage to the germ . Cereals In the context of these Standards, cereals refer to wheat, barley, oats, cereal rye, triticale, sorghum, maize and rice. Cereal Smuts Cereal Smuts include all smuts on all cereal grains. This includes but is not limited to: Ball Smut Are those infected by the spores of the fungus Tilletia caries . They have the appearance of pale, plump, slightly oversized grains. These grains are easily crushed between the fingers and contain a mass of black powder (spores) with a distinctive rotten eg g smell. This may also be called Stinking Smut or Bunt. Covered Smut Covered smut is caused by various fung i of Ustilago spp. Loose Smut Loose smut is the result of the fungus Ustilago tritici developing in the barley heads during the growing phase. The tolerance applies to the weight of all pieces of loose smut material (except kernels) in the half litre sample . A nil tolerance applies to all smuts in kernels. Chemicals not Approved for Barley Refers to the following :
63. GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 63 of 64 If the GREEN (GO) end does not go through then the slot fails . Record this event and move on to the next slot. If the GREEN (GO) end does go through then the slot size is greater than the nominated size of the GREEN end. Proceed to test th e slot with the RED (NO GO) end as follows: I f the RED (NO GO) end does not go through then the slot size is less than the nominated size of the RED end and greater than the nominated size of the Green End, hence the slot is within the accepted range and passes. If the RED (NO GO) end does go through then the slot fails . Record this event and move on to the next slot. Proceed to test all 74 slots, recording each failure. Repeat the above process for both screens i.e., the 2.50mm and 2.20mm screen. 0 to 25 slots is an acceptable failure rate. If the screen meets the tolerances: Record results on the equipment record Affix the relevant calibration sticker to the side of the sieve (not the catch pan) 5.20.6 References Not applicable.

Frost D amaged Refers to grain damaged as a result of fr ost during the maturation phase. Frost Damag ed barley grains appear pinched and sunken in on the back, usually on the awn half of the grain. In severe cases the kernel under the husk may appear orange. This definition is to be read in conjunction with the photo in the Visual Recognition Standards Guide which depicts the minimum affected standard for a grain to be classified as Frost Damaged. Germinative Capacity This is a measure of the barley grains capability to germinate . It is usually measured in the laboratory to assess germination o f potential late malt deliveries. Germinative Capacity is also referred to as viability. The methods used are based on the following IOB (Institute of Brewing) Methods (January 2007): 1.5 Germinative Capacity of barley: Hydrogen Peroxide and Peeling Technique (RM, EM) 1.6 Germinative Capacity of Barley: Rapid Staining Method (EM) Germinative Energy Germinative Energy m easures the germination of barley grains within a 7 2 hour period using a method of analysis based on the following IOB method (January 2007): 1.7 Germinative Energy of Barley (BRF Method) (EM) Grade Grade refers to the classification given to the barl ey load following sampling and full assessment according to these Standards. The Grade may be determined as a two stage process under specific conditions such as early or late deliveries , being:
56. GTA Barley Standards 20 1 4 /1 5 © Effective date: 1 August 201 4 Page 56 of 64 For Defective grains with tolerances above zero, assessment is made on grain from the Grower Load Composite sample. For nil tolerance defects, the tolerance (rejection of the load ) can apply if the defect is detected at any stage of the delivery or testing process, including in the truckload before sampling, in the probe sample, in the half litre sample or duri ng discharge into the receival hopper after assessment. G rain should be examined for defects under conditions of good lighting . Instruments of magnification may be used to assist the determination of the level of visually defective grains present in the s ample. For those defects with a tolerance based on the count in a 100 grain sample, a small sub sample should be drawn from the Grower Load Composite sample and placed on the 100 grain tray. Surplus grain should be removed from the tray when all 100 holes have been filled . Count the number of grains for the defect in question. For those defects with a tolerance based on the number of grains in a half litre sample (Insect Damaged , Heat Damaged, Bin Burnt or Storage Mould ), the entire half litre sample is t o be assessed. Count the number of grains for the defect in question. For those defects with a tolerance based on % by weight in a 100 gram sample ( B roken), a representative 100 gram sub sample should be drawn from the Grower Load Composite sample. Remove all Broken grain from the 100 gram sample and weigh. Each grain should be examined to determine if it is classified as defective. An individual kernel may only have one defect, being the defect type with the tightest tolerance in the standard. The presence and level of defective grains can be assessed with the assistance of the GT A Approved photographic standards (Visual Recognition Standards Guide) listed in Section 6 or Approved objective measurement instruments where appropriate (refer for exampl e Falling Number or Rapid Visco Analyser Reference Methods in Section 5 ). Report results as follows: Percentage by count in 100 grains – nearest 1% Count per half litre – nearest whole number Percentage by wt in 100 grams – nearest 0.1% 5.17.6 References Grain Quality Visual Recognition Standards – Australian Grains Centre, Co - operative Bulk Handling Ltd, October 2004.

Load A load is a bulk unit tendered for delivery. Loose Smut Refer to Cereal Smut for definition. Malt Grade Malt Grade is a grade of barley as defined within these Standards. Malt grade barley is highly desired for the malting process which involves a controlled process where barley has been allowed to sprout for use chiefly in brewing and distilling. Maximum Residue Limits M aximum Residue Limits (M RLs ) are the maximum amount of a chemical residue or its metabolite that is legally permitted on or in an agricultural commodity. The Australian Pesticides and Veterinary Medicines Authority (APVMA) sets MRLs. These MRLs are set at levels which are not likely to be exceeded if the agricultural or veterinary chemicals are used in accordance with approved label instructions and can be found on the ComLaw website at the following address http://www.comlaw.gov.au/Details/F2014C00821 Australian MRLs may differ significantly from those prescribed by foreign countries and the International Codex Alimentarius Commission. Consequently g rain exporters must be aware of MRLs of importing countries and which countries accept Codex MRLs. Foreign country MRLs may be accessed directly from foreign government websites or the NRS grains database at : http://www.daff.gov.au/agriculture - food/nrs/nrs - australian - and - overseas - mrl - database . Industry should always confirm the accuracy of these MRL l istings through their own means . Moisture This is the am ount of water present in the sample as determined by the appropriate analytic al method . N/A In these Standards means not applicable. That is, no minimum or maximum tolerance exists. The quality parameter may exist at unlimited levels in the sample. Nat ional Residue Survey The National Residue survey ( NRS ) gathers information and supplies chemical residue results on domestic and export grain commodities. The NRS results show Australian grain is of a high quality with respect to residues and contaminants. All grain exporters , container packers , bulk export t erminal operators, Bulk Handling Companies and processors are encouraged to actively participate in the NRS grains residue monitoring program. Contravention of an overseas MRL may cause the rejection of cargoes resulting in severe financial cost being incu rred and potentially jeopardising Australian grain into that market. Information about the NRS is located at : http://www.daff.gov.au/agriculture - food/nrs .

A primary sample is an individual probed sample taken from the lot presented for sampling A composite sample is the combined primary samples taken from the lot to be sampled, and is r epresentative of the entire lot A sub sample is the sample taken from the mixed composite sample for the purposes of conducting quality tests , and is representative of the entire l ot 5.2.2 Scope Barley is traded on the basis of quality tests conducted on lots of barley presented for sale or delivery to end users. Obtaining representative samples is critical to ensuring test results reflect the true quality of these lots. This procedure is applicable to all cereal grains, pulses and oilseeds. 5.2.3 Apparatus Manual sampling probe (double tube compartment probe, one inside the other, equipped with spiralled ports that open sequentially from bottom to top). Vacuum or pneumatic probe (an alter native to the manual sampling probe and consisting of a hand held or remotely controlled probe which retrieves grain through the use of a vacuum or other air movement system). Mixing bucket (including other associated equipment such as mini - auger suitable for mixing sample, optional). Sample dividing apparatus (optional) . 5.2.4 Reagents Not Applicable . 5.2.5 Procedure Sample Collection guidelines for collecting a rep resentative sample The surface of the grain should be fully exposed prior to sampling to allow for effective visual inspection. At this point, the load should be scanned for any defects or contaminants. The probe to be used should be of a sufficient l ength in order to obtain a sample from as close as possible to the bottom of truck.

Driver declares the variety (s) in the load tendered for delivery . It is recommended that the grower sign a Declaration Form and provide this to the driver for provision to the Receival Agent. This Declaration Form should at a minimum contain the grower details an d the variety(s) of the load. If the declared varietal composition or paddock where the grain was grown is different for each unit tendered for delivery, or more than one variety is commingled in each delivery unit, then a separate assessment of each uni t must be conducted. Note that depending on the varietal declaration and the procedures of the Receival Agent, a sample of the load may be taken and sent to a laboratory for assessment of the variety within the sample. In this instance sample is to be “as is”. Report the variety as per the following procedure using the applicable code as defined by the Receival Agent. Load is Declared as One Variety Only Where the load is declared as being of the one variety only, review the applicable maximum grade classification of that variety as per the Varietal Master List.

If contaminants are fo und, they shall be removed by hand and assessed in accordance with the tolerance prescribed in these S tandards under 5.18.1 . If any Stones are found above the 2.2mm and 2.5mm screen in the initial half litre sample, then a further four half litre samples should be taken. If the total weight of all Stones above the 2.2mm and 2.5mm screen found in the combined 2.5L sample is above 4.0g, the load is to be rejected. Seed contaminants are to be assessed using the appropriate visual assessment method and in accordance with the tolerance prescribed in these Standards under 5.18.1. Small Foreign Seeds (SFS) are assessed in the bottom tray (catchpan). These may need to be physically removed from all non - SFS material in the bottom tray. Alternatively, to assist in separating SFS from non - SFS material in the bottom tray, a mesh screen may be used. Place the sample over the mesh screen over a white tray and gentl y shake. SFS tend to remain on top of the mesh screen. Physical hand separation of SFS may still be required using this method. Seed Pods are to be assessed as a count per half litre where greater than 5mm in diameter . Where seed pods are not listed in the Standards and are 5mm or less in diameter, they are to be measured as part of Foreign Material . Any seed pods detected must not be opened . Pods refers to whole pods or part thereof. Where depicted, other contaminants should be assessed using the GT A Approved photographic standards. Where reference material is not available, other contaminants shou ld be assessed by reference to the Definitions of those parameters. For assessment of pickling compounds , chemicals not approved for grain or Chemicals in Excess of the MRL , it is recommended that all deliveries are accompanied by a signed declaration referring to its chemical status. Where the receiving agent believes that the visual appearance and/or odour of grain suggests that it has been treated with a non approved chemical, it is recommended t he grain is not received until the representative “as received” sample has been tested by an approved independent laboratory and the presence or absence of non approved chemicals ascertained.

If presenting the sample to the instrument in a pellet form, adjustments may be required to burn temperatures, times and blanks to compensate for the absence of a sample capsule. Blank and standard control/check samples should be repeated periodically ( as a guide every 10 samples) during each analytica l run to monitor any drift. Standard drift corrections and recalculation of samples should be made after analysis if the drift exceeds specification. Calculation of nitrogen content is usually performed automatically by the instrument data processing syst em or associated software. Results should be expressed as percent (5) nitrogen to two decimal places. For conversion to protein content “as is” multiply barley nitrogen by 6.25 % . Convert protein content to an 0 % moisture basis for barley for the nitrogen/protein values where necessary. Report result to the nearest 0.1%.

A larger RSD indicates the need for a finer grind or a larger analytical test weight, assuming that the in strument has been properly set up. For each batch the accuracy of the system is demonstrated by making ten successive determinations of nitrogen in nicotinic acid or tryptophan (different materials from calibration standard). Means of determinations must be ≤ ± 0.15 of respective theoretical values with standard deviation ≤ 0.15. Failure to achieve these values indicates the need for recalibration or optimisation of instrument settings. Accuracy checks should be carried out (1) On instrument installation and reinstallation following repairs and service; (2) When a new batch of working reference material is used; (3) After experiencing problems in instrument set up.
