This standard defines the testing methods and requirement for gloves that are designed to protect the user from thermal risks like heat and fire. Six performance level are measured:
- Burning behavior – the material of the glove is lit by flame for 15 seconds, after that the time of continuing burning or after glow is measured.
- Contact heat resistance – the glove is exposed to an object with temperatures form +100 C° to +500 C° and the time it takes for the glove temperature to increase by 10C° is measured.
- Convective heat resistance – the glove is exposed to a flame and the time it takes for the glove temperature to increase by 24C° is measured.
- Radiant heat resistance – the glove is placed on a hot object, then the time it takes for the heat to penetrate trough the glove is measured.
- Resistance to small splashes of molten metal – the number of small molten metal splashes are recorded that cause the glove inside temperature to rise by 40 C°.
- Resistance to large splashes of molten metal – large molten metal in different quantities is poured over the glove, while simulated skin is attached on the inside. The total weight in grams that will cause damage to the simulated skin is measured.
