Standard Test Method for Determining Water Holding Capacity of Fiber Mulches for Hydraulic Planting

SIGNIFICANCE AND USE
5.1 The meaning of the test is related to the manufacturing quality assurance and quality control and end use of the material, to determine characteristics of products. The water holding capacity of hydraulically applied mulches for hydraulic planting correlates directly with enhanced slurry and spray patterns by providing better soil/slurry binding ability, mixing ability in a tank, and rate of seed germination.
Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.
SCOPE
1.1 This quantitative test method determines the water holding capacity of fiber mulches, including wood, paper, and agriculturally derived and blended fiber mulches that are used for hydraulic seeding and planting. Results from this testing can be used as a quality assurance and/or quality control data for manufacturing processes.  
1.2 There are no known limitations to this test method.  
1.3 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. Reporting of test results in units other than inch-pound shall not be regarded as nonconformance with this standard. The amount of test water is presented in mL and no other unit of measurement is given.  
1.3.1 The gravitational system of inch-pound units is used when dealing with inch-pound units. In the system, the pound (lbf) represents a unit of force (weight), while the units for mass is slugs. The slug unit is not given, unless dynamic (F = ma) calculations are involved. This standard includes the gravitational system of inch-pound units and does not use/present the slug unit of mass.  
1.3.2 The slug unit of mass is typically not used in commercial practice; that is, density, balances, and so on. Therefore, the standard unit for mass in this standard is either kilogram (kg) or gram (g), or both.  
1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.  
1.4.1 The procedures used to specify how data are collected/recorded or calculated in the standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering data.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method evaluates the effect of an ECP on seed germination and initial plant growth in a controlled environment.  
5.2 The results of this test can be used to compare ECPs and other erosion control materials to determine which are the most effective at encouraging the growth of vegetation.
SCOPE
1.1 This test method covers guidelines, requirements, and procedures for evaluating the effect of Erosion Control Products (ECPs) on seed germination and vegetation enhancement.  
1.2 This test method will evaluate the effects of both rolled erosion control products (RECPs) and hydraulically-applied erosion control products (HECPs) on seed germination in a controlled environment.  
1.3 This test method utilizes bench-scale testing procedures and shall not be interpreted as indicative of field performance.  
1.4 This test method is not intended to replace full-scale simulation or field testing in acquisition of performance values that are required in the design of erosion control measures utilizing RECPs and HECPs.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM D6567-23(Test Method)
Standard Test Method for Measuring the Light Penetration of a Rolled Erosion Control Product (RECP)

SIGNIFICANCE AND USE
5.1 Light penetration may be used to control the quality of many RECPs. Light penetration has not been proven to relate to field performance for all materials.  
5.2 The light penetration of RECPs may vary considerably, depending on the composite materials used in the matrix of the mat or due to inconsistency within a given mat. To minimize variation, specific sample size and procedures are indicated in this test method to help ensure comparable results.  
5.3 This test method may be used to determine the effect of different composite materials and makeup of RECPs on the penetration of light.  
5.4 This test method may be used for acceptance testing of commercial shipments of RECPs. Comparative tests as directed in 5.4.1 may be advisable.  
5.4.1 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. At a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are formed from a lot of material of the type in question. The test specimens should be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student’s t-test for unpaired data and an acceptable probability level chosen by the two begun. If bias is found, either its cause must be corrected, or the purchaser and supplier must agree upon the known bias.
Note 1: The light penetration has no definitive relationship to the amount of ground cover provided by a RECP, as the amount of light penetration may include light passing through translucent elements or light deflecting off of elements of the RECP structure. Thus, this test method is not intended to be used to determine a...
SCOPE
1.1 This test method covers measuring the amount of light that penetrates through a rolled erosion control product.  
1.2 This test method does not provide light penetration values for RECPs under variable normal sun and soil conditions. This test method determines nominal light penetration.  
1.3 This test method is not to be used to determine a percent ground cover value for RECPs, as the amount of light penetration may include light passing through translucent material or reflecting off surfaces.  
1.4 The values stated as a percentage are to be regarded as the standard. The values provided in footcandles are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D8270-23b(Terminology)
Standard Terminology Relating to Cannabis

SCOPE
1.1 This terminology is a compilation of definitions of technical terms used in the cannabis industry. Terms that are generally understood or adequately defined in other readily available sources are not included.  
1.2 When a term is used in an ASTM document for which Committee D37 is responsible it is included only when judged, after review by Subcommittee D37.91, to be a generally usable term.  
1.3 Definitions that are identical to those published by other ASTM committees or other standards organizations are identified with the committee number (for example, D20) or with the abbreviation of the name of the organization (for example, IUPAC, International Union of Pure and Applied Chemistry).  
1.4 A definition is a single sentence with additional information included in discussions.  
1.5 Definitions are followed by the committee responsible for the standard(s) (for example, [D37.01]) and standard designation(s) in which they are used (for example, D8219).  
1.6 Abbreviated Terminology:  
1.6.1 Abbreviated terminology is intended to provide uniform contractions of terms relating to cannabis that have evolved through widespread common usage. The compilation in this standard has been prepared to avoid the occurrence of more than one abbreviated term for a given cannabis term and to avoid multiple meanings for abbreviated terms.  
1.6.2 The abbreviated terminology and descriptions in this standard are intended to be consistent with usage in the cannabis industry and the standards under D37 jurisdiction. Other ASTM committees may assign a different word-phrase description to the same abbreviated terminology. In such cases, the abbreviated terms in this standard shall apply to usage in D37 standards, or if widespread misunderstanding could result from conflicting abbreviated terminology descriptions, the abbreviated terminology for the word-phrase shall not be used in D37 standards.  
1.6.3 Acronyms and Initialisms—A word formed from the letters or parts of words of a longer word-phrase, usually from the initial letters or parts of the words. An acronym is pronounced as a word (for example, radar for radio detection and ranging). An initialism is pronounced as a series of letters (for example, DOT for Department of Transportation).  
1.6.4 The acronym or initialism description is the origin word-phrase for the acronym or initialism, not a definition.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Measuring Mass Per Unit Area of Turf Reinforcement Mats

SIGNIFICANCE AND USE
5.1 This test method is used to determine if the turf reinforcement mat meets specifications for mass per unit area. This test method can be used for quality control to determine specimen conformance. This measurement allows for a simple control of the delivered material by a comparison of the mass per unit area of the delivered material and the specified mass per unit area.  
5.2 The procedure in this test method may be used for acceptance testing of commercial shipments, but caution is advised since information about between-laboratory precision is incomplete. Comparative tests in accordance with 5.2.1 are advisable.  
5.2.1 In case of a dispute arising from differences in reported test results when using the procedures in this test method for acceptance testing of commercial shipments, the purchaser and the manufacturer should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. At a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and which are from a lot of material of the type in question. The test specimen should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using the appropriate Student’s t-test and an acceptable probability level chosen by the two parties before testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the manufacturer must agree to interpret future test results in light of the known bias.
SCOPE
1.1 This test method covers an index to the determination of mass per unit area of all turf reinforcement mats.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Guide for Whole Hemp Seed Storage at Primary Production Facilities

SIGNIFICANCE AND USE
4.1 Product wastage will be reduced if spoilage is avoided or the potential for spoilage is identified earlier in the process. High moisture can result in conditions favorable to microbial growth, mold, and conditions leading to rancidity.  
4.2 Testing for moisture content can assist in proactively managing damage to seed before it is not rectifiable or provide information to retarget seed to other feasible by-product streams.
SCOPE
1.1 This guide can be used by hemp farmers, hemp seed processing companies, and hemp agricultural extension agents to help manage against potential seed spoilage during storage.  
1.2 This applies to broadacre production of hemp seed intended for human consumption.  
1.3 This guide does not apply to hemp plants grown indoors or for purposes other than for harvesting of hemp seed intended for food within outdoor production conditions.  
1.4 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM D8493-23(Guide)
Standard Guide for Sample Preparation of Cannabis and Hemp Inflorescence for Laboratory Analysis

SIGNIFICANCE AND USE
5.1 The sample preparation procedure for comminution impacts other downstream processes such as extraction and sonication, which ultimately affects the total analytical error (TAE) and measurement uncertainty.  
5.2 Factors that may influence the sample preparation process include the prevention of cross-contamination (carryover) from a prior sample and an inadequate cleaning procedure between preparation of samples, poor sample handling, storage (sample preservation), and moisture content (drying methods) of plant material being greater than 15 % (15). Samples with high moisture content are hard to process completely and may yield lower analyte (that is, cannabinoid) concentration during extraction and further processing. Lastly, water activity Specification D8197 is recommended, activity (aw) range (0.55 to 0.65) for dry cannabis or hemp flower or both.  
5.3 There are many different types of hardware technologies that address the comminution of dried cannabis or hemp; however, the list of devices is exhaustive and thus beyond the scope of this guide. See Table 3 and Table 4  (16-18) for a summary of different milling technologies. Distinctions among various pieces of equipment often relate to the type, mass, and size/shape of the sample (dry, fibrous) for which each is most effective. In addition, there may be economic reasons for mill selection, that is, the sample throughput of the testing laboratory (number of samples per day), access to cryogenics, and sample mass requirements.    
5.4 In addition to sampling devices, this guide does not include the sample preparation of edibles, tinctures, oils/concentrates, beverages, and so forth in which the sample diversity poses significant sample preparation challenges to be put forward in additional work items.  
5.5 The sample size for comminution purposes is limited as the analytical testing portion required is often 500 times smaller than the bulk sample lot and not every testing laboratory is equipped to handl...
SCOPE
1.1 In this guide, the basic steps in obtaining a test portion sample of either dried cannabis/hemp inflorescence are outlined.  
1.2 Sample preparation depends on many factors including moisture (dryness) of the sample, the analyte to be measured, the concentrations/amounts, and the test method's precision and accuracy requirements. In this case, dried cannabis or hemp plant material require particle size reduction-comminution from a representative sample of which the final analytical testing portion is determined by the employed testing method. Local regulatory guidelines often dictate both the representative sample that is taken from the bulk material (harvest batch) and the final mass of the test portion (for example  
1.3 This guide will not purport to meet every local and state jurisdiction since different regulatory requirements vary; the local/state requirements are at the discretion of the user to follow and interpret.  
1.4 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM D8196-22(Practice)
Standard Practice for Determination of Water Activity (aw) in Cannabis Flower

SIGNIFICANCE AND USE
5.1 This practice is designed for use on cannabis flower by cannabis producers, processors, dispensers, testing laboratories, and end users. aw testing at any point in the supply chain is an important element in ensuring the safety and quality of cannabis flower. Testing can occur spontaneously at any point in the supply chain by regulatory agencies, suppliers, and customers.  
5.2 This practice is an important endpoint in determining whether a cannabis flower sample is being stored under optimal storage conditions (see Specification D8197).  
5.3 Analysis of water activity should be considered an important quality control step in ensuring a cannabis flower sample is being stored under optimal storage conditions to prevent mold and/or other microbiological growth and/or breakage.  
5.4 Maintaining the requisite aw throughout the supply chain from completion of drying through merchandising ensures safety and quality for the consumer.  
5.5 Water activity is used in many cases as a critical control point for Hazard Analysis and Critical Control Points (HACCP) programs. Controlling aw should not be seen as a kill step.5 Rather control of aw focuses on preventing the growth and proliferation of microorganisms.  
5.6 This practice is designed for use by trained technical individuals with minimal knowledge of complex analytical chemistry procedures.
SCOPE
1.1 This practice covers the recommended procedure for determining the water activity (aw) of a cannabis flower sample.  
1.2 Units—The values stated in SI units are to be regarded as the standard. Water activity is a ratio, and thus is without unit designation.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D8197-22(Specification)
Standard Specification for Maintaining Acceptable Water Activity (aw) Range (0.55 to 0.65) for Dry Cannabis Flower Intended for Human/Animal Use

ABSTRACT
This specification prescribes the recommended range of water activity (aw) suitable for safe and efficacious storage of cannabis flowers or portions thereof. Water activity (aw) is defined as the partial vapor pressure of water in a substance divided by the partial vapor pressure of pure water at the same temperature, which can be calculated by dividing the partial vapor pressure of water in the substance by the partial vapor pressure of pure water at the same temperature. This describes quantitatively the capability of the cannabis flower in a sealed container to affect the humidity of the container's headspace air. aw shall be less than 0.65 to ensure against undesirable growth of microorganisms such as mold, and shall be greater than 0.55 to ensure against physical damage (breakage) in routine handling and storage. If aw exceeds 0.68, further drying of the cannabis flower(s) shall be required to ensure that the aw is in the range 0.55–0.65. If aw is less than 0.68, co-storage with a salt-based aw (relative humidity) control sachet(s) designed to maintain the relative humidity between 0.55 to 0.65 can effectively bring the stored cannabis flower(s) into the specified 0.55–0.65 range. Storing cannabis flower with appropriately designed aw (relative humidity) salt-based control sachets intended to ensure a relative humidity of 0.55 to 0.65 in sealed containers can maintain the optimum storage conditions.
Maintaining the requisite aw throughout the supply chain from completion of drying through merchandising ensures safety and quality for the consumer.
SCOPE

Standard Practice for Cannabis or Hemp Supplier Lifecycle Management

SIGNIFICANCE AND USE
4.1 This practice is intended to be used by cannabis or hemp operators, or both, to establish good supplier lifecycle management practices.  
4.1.1 Without proper oversight, the quality and reliability of supplied materials, equipment, parts, software, or services can degrade. This can create issues that directly impact the operation's performance and remain undetected until customers experience a problem.  
4.1.2 Early identification and mitigation of risks within the supply chain are crucial to controlling costs and minimizing potential impacts on operations, customer experience, and business reputation. In general, costs are reduced when issues are prevented early and upstream in the supply chain.  
4.2 This practice applies to the cannabis or hemp horticulture, agriculture, processing, manufacturing, testing, and distribution operators and the many suppliers that provide materials, equipment, parts, software, or services to these operations.  
4.3 This practice provides operations and consultants supporting operations with the actions required to implement good supply and supplier management practices.  
4.4 Any supply chain operator can use this practice to conduct an internal gap assessment and risk analysis to identify opportunities for improvement.  
4.5 Certification bodies can use the standard to develop supplier audit programs.  
4.6 Section 5 provides details on the supplier lifecycle management process that includes the following seven activities:  
4.6.1 Supply and supplier information management.  
4.6.2 Supply identification and specifications.  
4.6.3 Supplier options, evaluation, and selection.  
4.6.4 Supplier onboarding.  
4.6.5 Supplier performance and risk management.  
4.6.6 Supplier relationship management.  
4.6.7 Supplier offboarding.
