ASTM WK60820

    New Practice for Separation of Ignitable Liquid Residues from Fire Debris Samples by Active Headspace Concentration onto an Adsorbent Tube

    (What is a Work Item?)

    Developed by Subcommittee: E30.01 | Committee E30 | Contact Staff Manager


    1. Scope

    1.1 This practice describes the procedure for separation of ignitable liquid residues from fire debris samples using the method of active headspace concentration onto an adsorbent tube for subsequent solvent elution or thermal desorption. 1.2 Active headspace concentration onto an adsorbent tube takes place from a closed air-tight sample container (typically a jar, can, or bag) using a syringe or pump. 1.3 Active headspace concentration systems for adsorption onto an adsorbent tube are illustrated and described. 1.4 This practice is suitable for extracting ignitable liquid residues over a range of concentrations (L/L to mL/L). 1.5 This practice is more suitable than the static headspace method (Practice E1388) for extracting ignitable liquid residues when a (very) low concentration of ignitable liquids (less than 10 L/L, see Practice E1388) is expected in the sample. 1.6 The principle of this practice is similar to the principle of the dynamic headspace concentration method (Practice E1413) but potentially less sensitive and non-destructive because only a single volume of the headspace from a sample container is sampled. 1.7 Alternative headspace concentration methods are Practices E1388, E1412, E1413, and E2154. 1.8 This practice requires a base of knowledge that is too extensive to be completely contained herein. As a result, this practice is intended to be used by individuals with the 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.

    This method is widely used in Europe but is not adequately addressed in the current Practice E1413.
