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.

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.  
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 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
1.1 This specification covers the recommended range of aw suitable for safe and efficacious storage of cannabis flowers or portions thereof.  
1.2 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.  
1.3 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 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.

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.  
4.7 To implement supplier management, follow the process in Sections 5 and 6. Start by applying the principles in this practice to a few supplies and suppliers and work through all of the step...
SCOPE
1.1 This practice provides cannabis or hemp operations, or both, with methods, procedures, responsibilities, and criteria for supplier management practices to reliably receive supplies that meet specifications. Effective supplier management includes clear concise communication and comprehension between departments and business functions, that is, marketing, finance, operations, supply requirement analysis, supplier assessment or audits, supplier selection, backup suppliers, and supply/supplier information management.  
1.2 In this practice, the term cannabis can be substituted with the term hemp. This practice applies to industrial hemp operations, CBD operations, and as referred to by several authorities having jurisdiction, licensed marijuana operations.  
1.3 This practice provides a process for supplier management in Section 5 and criteria for supplier evaluation in Section 6.  
1.4 Nothing in this practice shall preclude observance of federal, state, or local regulations which may be more restrictive or have different requirements.  
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 D8469-22(Test Method)
Standard Test Method for Analysis of Multiple Elements in Cannabis Matrices by Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

SIGNIFICANCE AND USE
5.1 Medical and/or recreational marijuana (cannabis) has been legalized for adult use in many countries and states within the USA (5). Many jurisdictions that permit the use of medicinal and recreational marijuana require testing of cannabis and associated products to ensure safety from contaminants, especially the toxic “big four” elements such as As, Cd, Hg, and Pb (6), and other metals worthy of consideration (6). These heavy metals can accumulate in plants grown in polluted soils or contamination can occur during the manufacturing process (7). In addition to ensuring product safety, the analysis of mineral and other trace elements is required for labeling purposes when these products are sold as nutritional supplements. Trace element analysis of plant and nutritional supplement materials is a well-established application (8). Following acidic digestion to break down the plant-based samples' primary components, ICP-MS is often used for quantitative analysis because of its multi-element capability, high sensitivity, speed, robustness, and wide dynamic range.  
5.2 This test method covers the rapid determination of multiple elements in cannabis sample digests. The elements include the priority toxic elements (As, Cd, Hg, and Pb), as well as elements required by some states and elements of interest in the cannabis community (V, Cr, Cu, Zn, Sb, Ba, Se, Ag, Na, Al, K, Mn, Fe, Co, Ni, Mo, Tl, Th, and U). Irrespective of the number of elements being measured, test times are approximately a few minutes per test specimen, and detectability for most elements is in the low- to sub-ppb range.
SCOPE
1.1 This test method uses inductively coupled plasma mass spectrometry (ICP-MS) to determine multiple trace elements in cannabis and cannabis-related matrices following sample preparation using microwave-assisted acid digestion. This test method is applicable to the quantification of trace levels of elements in dried plant materials, concentrates, oils, extracts, tinctures of cannabis and cannabis-related products. Other matrices may be added provided that the lab validates the extra matrices using Practice D8282. Details are provided on the validation of both the sample preparation procedure and analytical method using certified reference materials (CRMs) and validation of the analytical method using spike recovery testing of several cannabis based samples.  
1.2 This test method should be used by analysts experienced in the use of microwave digestion and ICP-MS, matrix interferences, and procedures for their correction or reduction, and should only be used by personnel trained in the handling, preparation, and analysis of samples for the determination of trace elements in cannabis and cannabis products (1).2 This test method was developed using a single quadrupole ICP-MS equipped with a collision/reaction cell (CRC) that can be pressurized with helium (He) gas for the removal of polyatomic interferences using kinetic energy discrimination (KED). This test method can also be run using a triple quadrupole or “tandem” mass spectrometer (MS/MS) ICP-MS instrument, which is fitted with CRC technology. The ICP-MS method accounts for polyatomic interferences, which are the most common spectral overlaps in ICP-MS, isobaric interferences, and any potential doubly-charged ion interferences (M2+) that may arise from the presence of rare earth elements (REEs) in the samples, as the REE2+ ion interferences can affect the accuracy of the measurement of arsenic (As) and selenium (Se) in the samples. Table 1 lists elements for which the test method applies along with recommended analytical masses, and secondary masses for some elements. The priority toxic elements arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb), also sometimes referred to as the “big four” toxic trace elements are listed separately because of their toxicity, as discussed in 5.1.

Standard Test Method for Determination of Cannabinoids in Cannabis Raw Materials and Resin Cannabis Products by Gas Chromatography and Flame Ionization Detection

SIGNIFICANCE AND USE
5.1 Gas chromatography and flame ionization detection provides a rapid means to identify and quantify cannabinoids in a variety of samples of interest. This test method allows producers of cannabis products to improve and optimize the quality of their products. For example, hemp extractors can use it to determine the efficiency of extraction processes and to verify that products meet regulatory requirements, ensuring safety and quality of products.  
5.2 Cannabinoids, such as CBD and THC can be monitored throughout the production process. The determination of Δ9-THC is often required for regulatory purposes and the determination of other THC isomers is often of interest. The United Nations Office on Drugs and Crime provides experimental details and guidance for use of GC to analyze cannabis related samples, including conditions suitable for decarboxylation of cannabinoid acids.3  
5.3 Post-decarboxylated methodology is used. In decarboxylation, heat is used to liberate carbon dioxide from carboxylic acid cannabinoids, forming their corresponding neutral cannabinoids, for example, THC from THCA. It should be recognized that the hot temperature of the GC injection port itself is capable of effecting at least some decarboxylation (250 °C – Table 2), and many sample types, such as distillates, require no decarboxylation because it would have occurred during material processing. Therefore, some knowledge of sample properties and material processing is useful. Resulting determinations are for the total cannabinoid content of specific isomers, for example, total Δ9-THC. For those samples requiring decarboxylation, the method is validated per Practice D8282 through the use of reference materials, spike and recovery of knowns, or through comparison with LC results. For example, carrying out the decarboxylation procedure of a standard containing known amounts of CBDA and CBN should yield the correct amounts of CBD and CBN, where CBN is not significantly changed and the mass...
SCOPE
1.1 This test method covers the analysis of cannabinoids in cannabis products by gas chromatography (GC) and flame ionization detection (FID).  
1.2 This test method is applicable to cannabis raw materials and resin cannabis products as defined in Guide D8245, including those from hemp. Such material includes: biomass; plant material; flowers; resins; extracts; distillates; recovered solvents; and other intermediate processing material. The applicable concentration range of analysis will vary to some extent depending on the nature of the sample, for instance measurement of delta-9-tetrahydrocannabinol (Δ9-THC) for regulatory purposes in hemp would require calibration to lower concentration levels compared to measurement of CBD in its isolate; however, in most cases, the test method is applicable to the determination of major and minor cannabinoids above about 0.1 mass% in concentration. Dilution of sample solutions is used to adjust concentrations to fall within appropriate calibration curves. Particular emphasis is placed on the determination of Δ9-THC for regulatory compliance purposes and control. This test method can measure any cannabinoid that is eluted and detected from a GC column with sufficient resolution from any interfering compounds. Typical cannabinoids of interest that can be determined by this test method are shown in Table 1. Use of an HPLC technique is recommended if individual measurement of acids, such as THCA, is required.  
1.3 The test method does not purport to identify all individual cannabinoids; however, individual users can adapt this test method for specific custom analyses to meet their needs.  
1.4 Units—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 t...

4.1 Certificate programs within the cannabis/hemp industries are offered by community colleges and universities, government agencies, employers, independent for-profit training organizations, and professional and trade associations. With the growth of these industries, an increased need for certificates is expected. While quality guidelines do exist for continuing education and training providers in general (for example, ANSI/IACET 1-2019), and for entities offering personnel certification programs (for example, ANSI/ISO/IEC 17024:2017), currently, no guidelines exist specifically to aid entities offering certificate programs within the cannabis industry. This practice aims to standardize and improve the quality of certificates and has been developed to:  
4.1.1 Provide certificate program developers and certificate issuers guidelines for quality program development and administration;  
4.1.2 Form the foundation for a recognition or certification system, or both, that enable consumers, employers, government agencies, and others who rely upon a skilled workforce to distinguish between qualified and unqualified workers; and  
4.1.3 Assist stakeholders in differentiating between certificate programs from personnel certifications.  
4.2 In a certificate program, an individual participates in a learning event or series of events designed to assist him or her in achieving specified learning outcomes within a defined scope; the individual receives a certificate only after verification of successful completion of all program requisites including but not limited to an assessment of learner attainment of intended learning outcomes.  
4.3 In contrast, in a certificate program, the learning event(s) and the assessment(s) are both developed and administered by the certificate issuer. There is an essential link between them. The learning event(s) are designed to help participants achieve learning outcomes and the assessments are designed to evaluate the learners’ attainment...
SCOPE
1.1 This practice provides protocols to certificate issuers for developing and administering certificate programs for stakeholders within the cannabis and hemp industries for determining best practices for administering professional or procedural certificate programs within the industries.  
1.2 This practice includes requirements for both the certificate issuer and requirements for the specific certificate programs issuing certificates.  
1.3 This practice provides the foundation for recognizing or certificate issuers to issue certificates to individuals after completing a certificate program.  
1.4 This practice addresses certificate programs for entities seeking certificates and inclusive of individuals, groups, or organizations and is applicable to training-based certificates for personal development and organizational-related certificates to existing standards or guidelines.  
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.

Standard Guide for Sampling of Hempseed Intended for Human Consumption

SIGNIFICANCE AND USE
4.1 Use of consistent procedures results in samples that reflect the quality or safety or both of the batch or lot from which samples were taken.  
4.2 Sampling for periodic testing is an important component for maintaining the requisite quality and safety aspect(s), particularly for buyers of raw product or other circumstances in which a further pathogen reduction step is not possible. It may also facilitate identification of product to be assigned to other appropriate usage, storage, or transport options.  
4.3 Consistent test results can enhance confidence of the buyer and credibility of the seller and allow for consistent product sourcing based on category of attribute or product specification.
SCOPE
