在ENFSI“火器”专家工作组的框架内，每两年进行一次扫描电子显微镜/能谱X射线探测和识别火药残留物的能力测试。本次能力验证是对原能力验证GSR 2001的发展和延伸。测试材料再次由组织小组设计，并由外部公司制造SEM配件。这一次，要求参与的实验室按照其自己的实验室特定的自动GSR颗粒搜索和SEM/EDX检测方法，确定测试样品上含PbSbBa颗粒的总数。将一份含有人造GSR颗粒的合成颗粒样品（SPS）分发给所有参与者。本文总结了研究结果，并评估了参与实验室的整体表现。此外，进行了扩展的统计评价和与以往研究的比较。
Within the framework of the ENFSI Expert Working Group "Firearms," every second year, a proficiency test on the detection and identification of GSR by SEM/EDX is carried out. This proficiency test is a development and extension of the previous proficiency test GSR2001. The test material was again designed by the organization panel and manufactured by an external company for SEM accessories. This time the participating laboratories were requested to determine the total number of PbSbBa containing particles on a test sample following their own laboratory specific methods of automated GSR particle search and detection by SEM/EDX. One synthetic particle sample (SPS) with artificial GSR particles was dispatched to all participants. This paper summarizes the results of the study and assesses the overall performance of the participating laboratories. Furthermore an extended statistical evaluation and a comparison with previous studies was carried out.
