Firstly, this standard tests, on a scale of 1 to 4, the resisted duration to flame persistence: this is based on the length of time the material continues to burn and glow after the source of ignition is removed.
Then, the resistance to contact heat is tested: it is based on the temperature range (100-500°C) at which the user will feel pain for at least 15 seconds.
Furthermore, the resistance to convective heat is tested: this test is based on the length of time the glove is able to delay the transfer of heat from a flame.
Then, the resistance to radiant heat is tested: this is measured with the length of time the glove is able to delay the transfer of heat when exposed to a radiant heat source.
After that, the resistance to small projections of molten metal is tested: this is measured with the number of molten metal drops that are required to heat the glove to a given level, from under 5 drops to under 35 drops.
Finally, the resistance to large splashes of molten metal is tested, and this test determines the weight of molten metal that is required to cause smoothing or pin holing across a simulated skin placed directly behind the glove sample, from 30g to 200g.
