(Practice)Standard Practice for Sampling of Headspace Vapors from Fire Debris Samples
Standard Practice for Sampling of Headspace Vapors from Fire Debris Samples
SCOPE
1.1 This practice covers the procedure for removing small quantities of ignitable liguid residue from samples of fire debris by sampling the headspace of the debris container.
1.2 Separation and concentration procedures are listed in the referenced documents. (See Practices E1385, E1386, E1412, and E1413.)
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 and health practices and determine the applicability of regulatory limitations prior to use.
