Designation:E232914Standard Practice forIdentification of Seized Drugs1This standard is issued under the fixed designation E2329;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice describes minimum criteria for the quali-tative analysis(identification)of seized drugs.1.2 Listed are a number of analytical techniques for theidentification of seized drugs.These techniques are grouped onthe basis of their discriminating power.Analytical schemesbased on these groupings are described.1.3 Additional information is found in Guides E1968,E1969,E2125,and E2548 and Practices E2326,E2327,E2549,and E2764.1.4 This practice does not replace knowledge,skill,ability,experience,education or training and should be used inconjunction with professional judgment.1.5 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E1968 Guide for Microcrystal Testing in Forensic Analysisof CocaineE1969 Guide for Microcrystal Testing in Forensic Analysisof Methamphetamine and AmphetamineE2125 Guide for Microcrystal Testing in Forensic Analysisof Phencyclidine and Its AnaloguesE2326 Practice for Education and Training of Seized-DrugAnalystsE2327 Practice for Quality Assurance of Laboratories Per-forming Seized-Drug AnalysisE2548 Guide for Sampling Seized Drugs for Qualitative andQuantitative AnalysisE2549 Practice for Validation of Seized-Drug AnalyticalMethodsE2764 Practice for UncertaintyAssessment in the Context ofSeized-Drug Analysis2.2 Other Document:SWGDRUG Scientific Working Group for the Analysis ofSeized DrugsRecommendations for:Education andTraining,Quality Assurance,Methods of Analysis33.Terminology3.1 DefinitionsTerms that may assist in interpreting thispractice are found in the SWGDRUG glossary.34.Significance and Use4.1 These are minimum requirements applicable to theidentification of seized drugs.4.1.1 As these are minimum requirements,it should berecognized that they may not be sufficient for the identificationof all drugs in all circumstances.Within these requirements,itis up to the individual laboratorys management to determinewhich combination of analytical techniques best satisfies therequirements of its jurisdiction.4.2 Correct identification of a drug or chemical depends onthe use of an analytical scheme based on validated methods(see Practice E2549)and the competence of the analyst.It isexpected that in the absence of unforeseen error,an appropriateanalytical scheme effectively results in no uncertainty inreported identifications(see Practice E2764).4.3 This practice requires the use of multiple uncorrelatedtechniques.It does not discourage the use of any particularmethod within an analytical scheme.Unique requirements indifferent jurisdictions may dictate the actual practices followedby a particular laboratory.5.Categories of Analytical Techniques5.1 For the purpose of this practice,techniques for theanalysis of drug samples are classified into three categories(see Table 1)based on their maximum potential discriminatingpower.However,the classification of a technique may be1This practice is under the jurisdiction of ASTM Committee E30 on ForensicSciences and is the direct responsibility of Subcommittee E30.01 on Criminalistics.Current edition approved Dec.1,2014.Published December 2014.Originallyapproved in 2004.Last previous edition approved in 2010 as E2329 10.DOI:10.1520/E2329-14.2For 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.3Available from the Scientific Working Group for the Analysis of Seized Drugs(SWGDRUG),http:/www.swgdrug.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 lower,if the sample,analyte,or mode of operation diminishesits discriminating power.5.1.1 Examples of diminished discriminating power mayinclude:5.1.1.1 An infrared spectroscopy technique applied to amixture which produces a combined spectrum,and5.1.1.2 Amass spectrometry technique which only producesmolecular weight information.6.Identification Criteria6.1 This practice requires that the following minimumcriteria be utilized when making analytical identifications:6.1.1 When a validated Category A technique is incorpo-rated into an analytical scheme,at least one other technique(from either Category A,B,or C)shall be used.6.1.2 When a Category A technique is not used,at least
