Molten metal is then poured over the glove material. Resistance to large splashes of molten metal: glove material.Resistance to small splashes of molten metal: The test is based on the total number of drops of molten metal required to increase the temperature by 40☌ between the inside of the glove and the skin.The average time is measured for heat penetration of 2.5 kw/kvm. Resistance to radiant heat: The glove’s material is stretched in front of a heat source with an effect of 20-40 kw/kvm.Resistance to convective heat: The amount of time is measured for the heat from a gas flame (80Kw/kvm) to increase the temperature of the glove’s inside material by 24☌.For example: to be marked with class 2, the glove’s inside material must manage 250☌ heat for 15 seconds before the material exceeds 35☌. 15 seconds is the minimum accepted length of time for approval. The length of time is then measured for how long it takes the material on the inside of the glove to increase by 10☌ from the starting temperature (approx. Resistance to contact heat: The glove’s material is exposed to temperatures between +100☌ and +500☌.After the gas flame is distinguished, the length of time is measured for how long the material either glows or burns. The flame is held against the material for 15 seconds. Resistance to flammability: The glove’s material is stretched and lit with a gas flame.The data is used to determine the load required to cut through the sample. The distance travelled to cause cut through at various forces is recorded. The sample is cut five times, each with three different loads. The blade is replaced with a new one to ensure accuracy.

A straight blade is loaded into the machine. When the metal blade touches the metal strip, the test is terminated.

The protection factor is then indicated on a scale from 1 to 4. Puncture as per EN 388 is 2: Puncture resistances based on the amount of force required to pierce the sample with a standardly sized point.
