1.1 本规程涵盖了法医实验室人员使用的培训指南，法医实验室人员负责培训将进行头发检查的法医，包括头发的显微镜比较。 1.2 法医毛发检验师按照惯例进行培训 E2917 以及特定学科的指导方针（指南 E3316 )以及该实践中的标准。 1.3 该实践包含指导方针，包括任务、目标和目标，使受训者能够获得必要的知识、技能和能力，在头发显微镜检查中独立执行个案工作。 1.4 该实践解决了显微镜检查的分析结果与DNA分析潜力之间的相关性。 1.5 该实践涉及头发显微镜检查的培训，而不是头发表面化学变化（例如染发剂）或微量物质（例如头发护理产品）的检查。 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）。本标准的使用者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》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 4.1 培训项目为受训人员成为合格的法医毛发检查员提供了必要的理论基础和实践技能。 4.2 受训人员在整个培训过程中由合格的考官直接监督。 在培训项目结束时，一名成功的受训者能够形成意见，提出和解释证据，并基于可靠的科学知识、经过验证的程序和实践经验理解分析结果和解释的局限性。 4.3 受训人员必须符合实践中的最低培训标准 E2917 以及这种做法。实验室管理层有责任确保选定的受训人员具有适当的教育背景。建议学员至少拥有自然科学学士学位。 4.4 本文件概述了课程、实践练习以及监测和评估受训人员进度的标准，旨在纳入整体实验室培训计划。 4.5 除此处列出的培训外，还应向受训人员提供其他培训。 此类培训可能包括场外课程、实习和由经验丰富的考官进行的专业培训。继续教育和培训将为法医提供在该领域保持现状的机会。 4.6 可以对经过化学改变的头发（例如染色的头发）或表面有微量物质（例如闪光粉）进行额外的分析。这些技术超出了本文件的范围。 4.7 这一做法解决了以下DNA分析显微镜检查的好处。

1.1 This practice covers training guidelines for use by forensic laboratory personnel responsible for training forensic examiners that will perform hair examinations, including microscopical comparisons of human hair. 1.2 Forensic hair examiners are trained in accordance with Practice E2917 and the discipline-specific guidelines (Guide E3316 ) and criteria within this practice. 1.3 This practice contains guidelines that include the tasks, goals, and objectives that allow the trainee to acquire the requisite knowledge, skills, and abilities to independently perform casework in the microscopical examination of hair. 1.4 This practice addresses the correlation between the analytical results of microscopical examinations and the potential for DNA analysis. 1.5 This practice addresses training for the microscopical examination of hairs and not the examination of chemical alterations (for example, hair dye) or trace materials on the surface of hairs (for example, hair care products). 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 ====== 4.1 A training program provides the theoretical foundation and practical skills necessary for a trainee to become a qualified forensic hair examiner. 4.2 A trainee is directly supervised by a qualified examiner throughout their training. At the end of the training program, a successful trainee is capable of forming opinions, presenting and explaining evidence, and understanding the limitations of analytical results and interpretations based upon sound scientific knowledge, validated procedures, and practical experience. 4.3 A trainee is required to meet the minimum training criteria in Practice E2917 and this practice. It is the laboratory management’s responsibility to ensure the selected trainee has the appropriate educational background. It is recommended that, at a minimum, the trainee possess a bachelor’s degree in a natural science. 4.4 This document outlines lessons, practical exercises, and criteria to monitor and evaluate trainee progress and is designed to be incorporated into an overall laboratory training program. 4.5 Additional training beyond that which is listed here should be made available to the trainee. Such training might include off-site courses, internships, and specialized training by experienced examiners. Continuing education and training will provide a forensic examiner the opportunity to remain current in the field. 4.6 Additional analyses can be performed on hairs that have been chemically altered (for example, dyed hair) or have trace materials on the surface (for example, glitter). Such techniques are beyond the scope of this document. 4.7 This practice addresses the benefit of following microscopical examinations with DNA analysis.
