Significance and Use
5.1 This procedure is intended to be used to evaluate the ignitability of liquid wastes.
5.2 Flash point measures the response of the subsample to applied heat and an ignition source under controlled laboratory conditions. It is only one of a number of properties that must be considered in assessing the overall flammability hazard of a liquid waste material.
5.3 Flash point can indicate the possible presence of highly volatile and flammable materials in a relatively nonvolatile or nonflammable material.
1.1 This test method covers the procedure for a finite flash point test, within the range of 20 to 70 °C, of liquid wastes using a manual or automated Pensky-Martens closed cup tester.
1.2 This test method contains two procedures and is applicable to liquid waste, liquid phase(s) of multi-phase waste, liquid waste with suspended solids, or liquid waste that tends to form a surface film under test conditions.
Note 1: If the liquid waste is of a viscosity such that the subsample volume will not be uniformly heated under the test conditions even with the increased stir rate of Procedure B, then use the small-scale method (Test Method for Finite Flash Point Determination of Liquid Wastes by Small-Scale Closed Cup Tester).
1.3 Procedure A is applicable to non-viscous liquids that are without suspended solids. Procedure B is applicable to viscous liquids, liquids with suspended solids, or liquids that form films.
Note 2: This test method is not applicable for corrosive liquid wastes (see Test Method ).
1.4 Units—The values given in SI units are to be regarded as the standard.
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Warning statements appear throughout. Also see applicable Safety Data Sheets (SDS) for information about certified reference materials (CRMs) or secondary working standards (SWSs) that may be used in the analysis. SDS may also be useful if some components of the waste sample are known.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
