Standard Classification for Ignitable Liquids Encountered in Fire Debris Analysis

Importancia y uso:

5.1 Classification features of ignitable liquids described herein are based upon distinguishing chemical features that are unique to each class. Components and features common to a class are also included but could be common to two or more classes of ignitable liquids.

5.1.1 Variation within a class can occur as manufacturers change formulations over time, use different feedstocks, add new processes, and respond to changes in regulatory requirements. It is impractical to provide criteria for every manufactured ignitable liquid.

5.2 Mixtures of ignitable liquids can be marketed as a single commercial product. This classification cannot differentiate between ignitable liquids that are mixed by a manufacturer for sale or ignitable liquids mixed at the point of use.

5.3 Refer to Test Methods E1618, E2881, and E2997 for additional guidance on the classification and identification of:

5.3.1 Products with one, or a few, individual chemicals which have their chemical names reported.

5.3.2 Mixtures that contain two or more distinct classes described in this classification.

5.3.3 Non-classifiable ignitable liquids.

5.3.4 Complications arising from matrix contributions, microbial degradation, or weathering effects of ignitable liquids.
