ISO 9038:2025 Determination of sustained combustibility of liquids

standard byInternational Organization for Standardization , 02/01/2025
This document specifies a procedure, at temperatures up to 100°C, to determine whether a liquid product, that would be classified as “flammable” by virtue of its flash point, sustains combustion at the temperature(s) specified, for example, in regulations.
u000bNOTE Many national and international regulations classify liquids as presenting a flammable hazard based on their flash point, as determined by a recognized method. Some of these regulations allow a derogation if the substance cannot “sustain combustion” at some specified temperature(s).
u000bThe procedure is applicable to paints (including water-borne paints), varnishes, paint binders, solvents, petroleum or related products and adhesives, that have a flash point. It is not applicable to painted surfaces in respect of assessing their potential fire hazards.
u000bThis test method is applicable, in addition to test methods for flash point, for assessing the fire hazard of a product.
