意义和目的
4.1 易燃和不易燃液体的混合物, 例如酒精和水的混合物, are classified by the US government according to the definition of flammable liquids based on the closed cup flash point method. 所以, mixtures can be classified as flammable even if they cannot withstand combustion. This test method determines the ability of a liquid mixture to sustain combustion and, when used in conjunction with the closed cup flash point method, indicates the flammability characteristics of the mixture.
