This standard helps to determine the flammability characteristics of materials by measuring the flash point of liquids using a small cup-closure instrument. Flash point measurement is an important property for evaluating the response of materials to heat and ignition sources and is widely used in transport and safety regulations. The standard applies to a wide range of liquids with flash points between 0 ° C and 110 ° C and provides testing options that are different from traditional Miscellaneous testing methods such as D56 and D93. The scope of application of different test methods and precautions are also covered in the standard.
