ASTM E2998 - 16 - Standard Practice for Characterization and Classification of Smokeless Powder

ASTM E2998 - 16

Standard Practice for Characterization and Classification of Smokeless Powder

Status : Current   Published : October 2016



1.1 This practice describes procedures for characterization and analysis of smokeless powders recovered from explosives incidents ( 1, 2), 2 materials or objects containing gunshot residue ( 3) when visible grains are present, or bulk samples of powder.

1.2 Smokeless powder is characterized by shape, color, texture, manufacturing toolmarks, markers, dimensional measurements, and chemical composition ( 4-6).

1.3 Smokeless powder is an energetic material classified as a low explosive or propellant. Smokeless powder can be further classified as single-base, double-base, or triple-base.

1.4 Analysis of post-blast debris and items containing gunshot residue when visible grains of smokeless powder are not present is beyond the scope of this practice.

1.5 This practice will provide guidelines for the analysis of organic components of smokeless powders using various instrumental techniques, such as gas chromatography-mass spectrometry, liquid chromatography, and Fourier transform infrared spectroscopy.

1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7  This standard involves handling of low explosives and potentially other energetic materials. It is strongly suggested that an analyst be trained in the storage and safe handling of energetic materials and be familiar with the properties and hazards of explosives.

1.8  This standard cannot replace knowledge, skill, or ability acquired through appropriate education, training, and experience and should be used in conjunction with sound professional judgment.

1.9  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 and health practices and determine the applicability of regulatory limitations prior to use.
