ASTM D4206 – Standard Test Method for Sustained Burning of Liquid Mixtures Using the Small Scale Open-Cup Apparatus
Description:
Significance and Use
4.1 Mixtures of flammable liquids and nonflammable liquids, such as an alcohol and water mixture, are classified by the U. S. Government by the definition of flammable liquid based on a closed-cup flash point method. Thus, mixtures may be classed as flammable even though they do not sustain burning. This test method determines the ability of a liquid mixture to sustain burning and, when used with a closed-cup flash point method, indicates the flammability characteristics of the mixture.
Scope
1.1 This test method2 describes a procedure for determining the sustained burning characteristics of mixtures of flammable and nonflammable liquids and to mixtures containing liquids with widely different flash points.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
