Significance and Use

5.1 This guide is designed to assist the analyst using polarized light microscopy for the examination of test samples for the presence of explosives.

5.2 Intact explosives and post-blast residues that contain unconsumed explosive components or their solid reaction products are suitable for this guide (Practices E3253 and E3329). Particles only a fraction of a millimeter in size can be examined using this guide.

5.3 This guide is not suitable for the examination of smokeless powder or liquid explosives.

5.4 Some of the microscopical techniques described in this guide allow for the recovery of the specimen for subsequent analysis, but others, such as microcrystal tests, are destructive.

5.5 Identifications of explosive-related components based on these properties shall be part of an analytical scheme as described in Practices E3253 and E3329.

Scope

1.1 This guide addresses the use of polarized light microscopy (PLM) to identify explosive-related compounds from intact explosives and post-blast residues containing unconsumed explosive compounds or their solid reaction products, and to isolate them for further analysis.

1.2 This guide 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).

1.3 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.
