Designation:D8334/D8334M20Standard Practice forSampling of Cannabis/Hemp Post-Harvest Batches forLaboratory Analyses1This standard is issued under the fixed designation D8334/D8334M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 Cannabis harvested materials require sampling strate-gies throughout their life cycle,from cultivation to the endconsumer.For purposes of this standard,the term cannabis isinclusive of all cannabis inflorescence,including hemp variet-ies.The qualitative and quantitative characteristics of cannabis/hemp for human or animal consumption has safety implica-tions throughout the life cycle from cultivation to endconsumer.This standard provides best practice procedures andprotocols for sampling batches of harvested cannabis inflores-cence.Cannabis/hemp materials often exhibit variability acrossdifferent parts within the same plant or across different plantswithin the same cultivar,or both,(1,2).2Thus,samplingstrategies are required which yield a representative a sampleacross a harvest batch.Representative sampling is required toensure that the qualitative and quantitative test results accu-rately reflect cannabinoid identification,potency,identificationand concentration of terpenes,concentration of trace metals,microbiological activity,mycotoxins,and concentration ofpesticides across the batch.1.2 Where procedural aspects of this practice differ fromlocal regulatory or jurisdictional requirements,the local regu-latory or jurisdictional authoritys directives shall take prece-dence.1.3 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard.Thevalues stated in each system are not necessarily exact equiva-lents;therefore,to ensure conformance with the standard,eachsystem shall be used independently of the other,and valuesfrom the two systems shall not be combined.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:3D8270 Terminology Relating to Cannabis3.Terminology3.1 DefinitionsFor general terms related to cannabis,seeTerminology D8270.3.2 Definitions of Terms Specific to This Standard:3.2.1 aliquot,na discrete quantity of a cannabis/hemp(raw material)inflorescence collected by laboratory personnel/certified/trained sample collectors that shall be combined intorepresentative samples for purposes of testing.3.2.2 cannabis,na genus of flowering plants within theCannabaceae family identified by their distinctive glandulartrichomes,divided serrated leaves,and tough bast fibers.3.2.2.1 DiscussionIn this standard,the term cannabis isused to mean cannabis raw material that includes resincannabis,nutritional cannabis,and industrial cannabis,thatincludes hemp,in a harvested raw material form.3.2.3 composite sample,na final mixture of all samplealiquots pulled within a specific harvest batch,homogenized,and labelled.3.2.4 harvest batch,na specifically identified quantity ofcannabis inflorescence,that is uniform in cultivar,harvestedwithin a concurrent time frame,and,cultivated using the samepesticides and other agricultural chemicals.3.2.5 inflorescence,na group or cluster of flowers ar-ranged on a stem that is composed of a main branch or a1This practice is under the jurisdiction of ASTM Committee D37 on Cannabisand is the direct responsibility of Subcommittee D37.03 on Laboratory.Current edition approved Nov.1,2020.Published November 2020.DOI:10.1520/D8334_D8334M-20.2The boldface numbers in parentheses refer to a list of references at the end ofthis standard.3For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1com
