1.1 This practice describes procedures applicable to the analysis of cocaine using multiple microcrystal tests (1-6).
1.2 These procedures are applicable to cocaine, which is present in solid form or an injectable liquid form. These procedures are not applicable to the analysis of cocaine in biological samples.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 These procedures are intended to be used as part of an analytical scheme (See Practice E2329).
1.4.1 These procedures could generate observations indicating a positive test for cocaine or its enantiomers which could be incorporated into the analytical scheme as defined by the laboratory.
1.5 This standard is intended for use by competent forensic science practitioners with the requisite formal education, discipline-specific training (see Practice E2917), and demonstrated proficiency to perform forensic casework.
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.
1.7 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.
