scope:

This practice describes the minimum requirements of a training program in primer gunshot residue (pGSR) analysis by scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS). It describes lessons, practical exercises, and progress monitoring and evaluation that should be part of a laboratory's training program.

The primary purpose of this practice is to facilitate the development and implementation of training programs in crime laboratories or other such analytical entities that participate in the detection, analysis, and classification of pGSR particles.
