1.1 本规程描述了对缉获药物进行定性分析（鉴定）的最低标准。 1.2 列出了一些用于识别缉获毒品的分析技术。这些技术根据其识别能力进行分组。描述了基于这些分组的分析方案。 1.3 更多信息请参阅指南 E1968年 , E1969年 , E2125 和 E2548 和实践 E2326 , E2327 , E2549 和 E2764 . 1.4 本标准应与良好的专业判断结合使用，不能取代通过适当教育、培训和经验获得的知识、技能或能力。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 这些是适用于识别缉获毒品的最低要求。 4.1.1 由于这些是最低要求，应认识到它们可能不足以在所有情况下识别所有药物。在这些要求范围内，单个实验室的管理层有责任确定哪种分析技术组合最符合其管辖区的要求。 4. 4.2 药物或化学品的正确识别取决于分析员的能力和使用包含验证方法的分析方案（见实践） E2549 ). 预计在没有不可预见的错误的情况下，适当的分析方案可以有效地产生可靠和科学支持的识别 5. （参见实践 E2764 ). 4.3 这种做法要求实验室的分析方案纳入在显著不同的原则下运行的技术。这并不妨碍在分析方案中使用任何特定方法。特定实验室遵循的实际做法可能取决于管辖要求。

1.1 This practice describes minimum criteria for the qualitative analysis (identification) of seized drugs. 1.2 Listed are a number of analytical techniques for the identification of seized drugs. These techniques are grouped on the basis of their discriminating power. Analytical schemes based 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 standard should be used in conjunction with sound professional judgment, and cannot replace knowledge, skill, or ability acquired through appropriate education, training, and experience. 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. ====== Significance And Use ====== 4.1 These are minimum requirements applicable to the identification of seized drugs. 4.1.1 As these are minimum requirements, it should be recognized that they may not be sufficient for the identification of all drugs in all circumstances. Within these requirements, it is the responsibility of the individual laboratory’s management to determine which combination of analytical techniques best satisfies the requirements of its jurisdiction. 4 4.2 Correct identification of a drug or chemical depends on the competence of the analyst and the use of an analytical scheme that incorporates validated methods (see Practice E2549 ). It is expected that in the absence of unforeseen error, an appropriate analytical scheme effectively results in reliable and scientifically supported identifications 5 (see Practice E2764 ). 4.3 This practice requires the laboratory’s analytical scheme to incorporate techniques that operate on significantly different principles. It does not discourage the use of any particular method within an analytical scheme. Actual practices followed by a particular laboratory may depend upon jurisdictional requirements.
