1.1 概述: 1.1.1 本试验方法提供了一种程序，用于在使用规范中描述的测试样本和统计考虑因素时表征现场便携式芬太尼检测设备和分析的性能 E3243 . 1.1.2 本试验方法描述了在实验室环境中表征各种类型现场芬太尼检测设备或分析性能时使用的样品制备和分析协议，包括气相色谱/质谱（GC/MS）、高压质谱（HPMS）、离子迁移谱（IMS）、傅立叶变换红外（FTIR）光谱、，拉曼光谱、比色分析和免疫分析。 1.1.3 该测试方法的目的是以类似于联邦和州/地方/部落/地区（SLTT）执法人员和第一响应者在现场分析样品的方式分析样品，但其控制和可再现性要比进行现场测试时通常可以实现的条件高得多。 1.2 单位: 1.2.1 当创建测试样品混合物时，所有浓度表示为固体样品混合物测试样品的重量/重量百分比（mg/mg），以及溶解在溶剂中的固体和液体测试样品的重量/体积（mg/mL）。当创建稀释液体测试样品时（例如，用于在分析之前检测溶解在溶剂中的化合物），所有浓度均表示为体积/体积百分比（例如，µL/mL）。 1.3 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。 1.4 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。

1.1 General: 1.1.1 This test method provides a procedure for characterizing the performance of field portable fentanyl detection equipment and assays when utilizing the test samples and statistical considerations described in Specification E3243 . 1.1.2 This test method describes sample preparation and analysis protocols to use when characterizing the performance of various types of field fentanyl detection equipment or assays in a laboratory environment including gas chromatography/mass spectrometry (GC/MS), high pressure mass spectrometry (HPMS), ion mobility spectrometry (IMS), Fourier Transform Infrared (FTIR) spectroscopy, Raman spectroscopy, colorimetric assays, and immunoassays. 1.1.3 The intent of this test method is to analyze samples in a manner that is analogous to how they are analyzed in the field by Federal and State/Local/Tribal/Territorial (SLTT) law enforcement and first responders, but under much more controlled and reproducible conditions than those that would generally be achievable when conducting field testing. 1.2 Units: 1.2.1 When creating test sample mixtures, all concentrations are stated as weight/weight percent (mg/mg) for solid sample mixture test samples, and weight/volume (mg/mL) for solid and liquid test samples that are dissolved in a solvent. When creating diluted liquid test samples (for example, for detection of compounds solubilized in solvent prior to analysis), all concentrations are stated as volume/volume percent (for example, µL/mL). 1.3 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. 1.4 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.
