There is a need for non-detonable training aids to enable training of canines when access to true material is limited. A disadvantage of non-detonable training aids is the lack of third-party independent verification and validation to certify the efficacy of the aid to yield a detection capability to true material. The goal of this research is to guide the development of a pipeline for the evaluation of commercial off-the-shelf (COTS) or novel training aids by using both analytical analysis as well as canine olfactory testing. Headspace analysis was carried out for nitrated explosive training aids, RDX and PETN, as well as peroxide explosives, HMTD and TATP. Batch-to-batch reproducibility and usage lifetime mimicking operational usage, were also assessed for peroxide explosive aids. As a result of the analytical analysis, various issues were identified such as limitations of explosive component detection, presence of extraneous odors, dynamic headspaces, and both inter- and intra- batch variability. A single TATP training aid was selected to be tested in a proof-of-concept canine assessment which compared canines trained using true material in their ability to detect the training aid in question and a set of canines trained solely with a COTS training aid in their ability to detect true material. It took the canines collectively nearly 21 trials of exposures to true TATP before all canines trained with the non-detonable training aid were able to detect the true TATP with a 100% detection rate, highlighting the importance of analytical characterization of non-detonable training aids paired with canine validation studies.

需要一种不可引爆的训练辅助工具，以便在获得真实材料有限的情况下能够对犬进行训练。不可引爆训练辅助设备的一个缺点是缺乏第三方独立验证和验证来证明辅助设备的有效性，以产生对真实材料的检测能力。这项研究的目标是通过使用分析分析和犬类嗅觉测试来指导开发用于评估商业现成 (COTS) 或新型训练辅助工具的管道。对硝化炸药训练辅助工具 RDX 和 PETN 以及过氧化物炸药 HMTD 和 TATP 进行了顶空分析。还评估了过氧化物爆炸助剂的批次间再现性和模仿操作使用的使用寿命。分析分析的结果是，发现了各种问题，例如爆炸物成分检测的局限性、外来气味的存在、动态顶空以及批次间和批次内的变异性。选择单个 TATP 训练辅助器具进行概念验证犬类评估测试，该评估比较了使用真实材料训练的犬只检测相关训练辅助器具的能力，以及一组仅使用 COTS 训练辅助器具训练的犬只的检测能力。检测真实材料的能力。在所有接受过不可爆炸训练辅助设备训练的犬只能够以 100% 的检出率检测到真正的 TATP 之前，这些犬只进行了近 21 次接触真正 TATP 的试验，这凸显了不可爆炸训练辅助设备分析表征的重要性与犬类验证研究相结合。
