1.1 本规程涵盖评估、选择和应用技术，以建立检验方案，供法医爆炸物检验员用于识别完整（未爆炸）的低爆和高能炸药。为完整炸药的一致分析方法奠定了基础。描述了按照有效测试顺序开发识别信息的方法。 1.2 本规程规定了使用视觉、物理、分析和仪器技术的要求，这些技术为识别高爆炸性或低爆炸性材料提供结构和化学信息。 1.3 炸药检验中使用的技术包括目视和显微镜检查、物理特性、点火敏感性测试、化学和现场测试以及仪器方法。 1.4 列出了识别常见爆炸物和爆炸材料的最低要求。 1.5 本标准旨在供受过必要的正规教育和专业培训的合格法医学从业人员使用（见实践） E2917 )，并证明熟练执行法医案例工作（请参阅T/SWGFEX建议的爆炸物分析培训指南）。 1.6 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。 1.7 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====== 5.1 本规程旨在协助法医爆炸物检查员选择和组织识别完整爆炸物的分析方案。样品的数量和条件以及适用仪器技术的可用性将决定所选的分析方案。 5.2 法医爆炸物审查员考虑与案件调查和提交项目有关的问题，例如样本量、复杂性和条件、环境影响和使用的收集方法。考虑因素包括测试方法、样品制备方案、测试顺序以及样品更改和消耗的可接受程度，每种提交的案例都会有所不同。 5.3 本规程提供了识别爆炸性材料的最低标准。审查员确定了一个分析方案，该方案使用技术来正确识别材料，其中可能包括氧化剂、燃料、粘合剂和检测剂。 5.4 本规程与参考文件一起使用。 5.5 本实践并不试图解决与样品分析有关的所有问题。可以进行额外的测试或分析，以进一步区分和表征样品。

1.1 This practice covers the evaluation, selection, and application of techniques to establish examination schemes for use by forensic explosives examiners to identify intact (unexploded) low and high explosives. A foundation for a consistent approach to the analysis of intact explosives is provided. Methods for the development of identifying information that follows an efficient order of testing are described. 1.2 This practice establishes requirements for the use of visual, physical, analytical, and instrumental techniques that provide structural and chemical information for an identification of a high or low explosive material. 1.3 Techniques used in the examination of explosives include visual and microscopical inspection, physical characterization, ignition susceptibility testing, chemical and spot testing, and instrumental methods. 1.4 The minimum requirements for identification of commonly encountered explosives and explosive materials are listed. 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 (refer to the T/SWGFEX Suggested Guide for Explosives Analysis Training). 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. ====== Significance And Use ====== 5.1 This practice is designed to assist the forensic explosives examiner in selecting and organizing an analytical scheme for identifying intact explosives. The amount and condition of the sample, as well as the availability of applicable instrumental techniques, will determine the selected analytical scheme. 5.2 The forensic explosives examiner considers relevant issues about the case investigation and submitted items, such as sample size, complexity and condition, environmental effects, and collection methods used. Considerations include test methods, sample preparation schemes, test sequences, and acceptable degrees of sample alteration and consumption that will be different for each case submission. 5.3 This practice provides the minimum criteria for identifying explosive material. The examiner determines an analytical scheme that uses techniques to correctly identify the material, which could include oxidizers, fuels, binders, and detection agents. 5.4 This practice is used in conjunction with the referenced documents. 5.5 This practice does not attempt to address all the issues regarding sample analyses. There could be additional tests or analyses performed to provide further discrimination and characterization of samples.
