Scope

1.1 This practice describes procedures applicable to the analysis of methamphetamine and amphetamine using microcrystal tests (1-6).2 1.2 These procedures are applicable to methamphetamine and amphetamine, which are present in solid dosage form or an injectable liquid form. These procedures are not typically applicable to the analysis of methamphetamine and amphetamine 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 could generate observations indicating a positive test for methamphetamine or amphetamine which could be incorporated into the analytical scheme as defined by the laboratory. 1.5 This standard cannot replace knowledge, skills, or abilities acquired through appropriate education, training, and experience (see Practice E2326) and is to be used in conjunction with sound professional judgment by individuals with such discipline-specific knowledge, skills, and abilities. 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.
