ÖNORM EN ISO 13736

This International Standard specifies a method for the determination of the closed cup flash Point of Petroleum products and other liquids having flash Points between -30C and 70C inclusive. However the precision given for the method is only valid for flash Points in the range -5C to 66,5C. This Standard is not applicable to water borne paints which may however be tested using ISO 3679. NOTES 1 This method should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions, and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. 2 Flash Point is used in shipping, storage, and handling and safety regulations as a classification property to define "flammable" and "combustible" materials. Precise definition of the classes is given in each particular regulation. 3 Flash Point may indicate the possible presence of highly volatile materials in a relatively non-volatile or non-flammable material. 4 Since the presence of small proportions of highly volatile materials need to be detected, this test should be the first determination on a received Sample. 5 Liquids containing halogenated compounds may give anomalous results.
