Standard Practice for Collection of Primer Gunshot Residue (pGSR) Particles from Clothing, Vehicles, and Other Inanimate Objects using Scanning Electron Microscopy (SEM) Stubs

Importancia y uso:

5.1 pGSR originates from the explosion of the priming mixture following ignition during the firearm discharge process. After a firearm has been discharged, residue can be found on exposed surfaces in the vicinity of the fired weapon (4, 5).

5.2 The most common reason for pGSR examination is to determine if an inanimate object was exposed to firearm discharge. Recovered pGSR can also provide information about the constituents of the priming mixture (4, 5).

5.3 This practice is applicable to the recovery of pGSR from objects in a controlled environment or location, such as a forensic laboratory, or in the field.

5.4 This practice provides recommendations to be followed in the collection of pGSR samples intended for forensic analysis.

5.5 This practice is intended to be used in conjunction with Test Method E1588 and Practices E1188, E1459, and E1492.
