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 heat and an ignition source under controlled laboratory conditions. It is only one of a number of properties that shall 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.
5.4 This test method uses a small sample volume (2 mL) and short test time (1 min).
1.1 This test method covers the procedure for a flash point test, within the range of –20 to 70 °C, of liquid wastes using a small-scale closed cup tester.
Note 1: Some apparatus are not designed for subambient temperature tests, so the testing range would be between 20 °C and 70 °C.
Note 2: This test method is not applicable for liquid waste that forms a surface film (see Test Method for Finite Flash Point Determination of Wastes by Pensky-Martens Closed Cup Tester).
1.2 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
1.3 This standard measures the ignitability properties of liquid wastes (which may be any discarded material), which may include secondary materials, off-specification products, and materials containing free liquids recovered during emergency response actions. Results from this test method may be used as part of a fire risk assessment of the material, but it is the responsibility of the user to perform any additional characterization needed for determination of storage, transport, treatment, or disposal per current regulations.
1.4 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. See applicable Safety Data Sheets (SDS) for information about certified reference materials (CRMs) or secondary working standards (SWSs) that may be used in this test method. SDS may also be useful if some components of the waste sample are known.
1.5 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.
