STANDARD EN 407:2004



This standard indicates thermal performance of a given glove against heat or fire.


The type and quality of protection is shown by a pictogram followed by a six-digit series, a to f relating to performance levels (always on a scale of 0 to 4) against specific protective qualities.

A. Resistance to Flammability

The glove’s material is stretched and lit with a gas flame. The flame is held against the material for 15 seconds. After the flame is extinguished, the length of time the glove either glows or burns is measured.

B. Resistance to Contact Heat

The glove’s material is exposed to temperatures between 100°C and 500°C. The length of time it takes the material on the inside of the glove to increase by 10°C from the starting temperature (approx. 25°C) is measured, and 15 seconds is the minimum accepted length of time for approval. To be marked with class 2, the glove’s inside material must manage 250°C heat for 15 seconds before the material exceeds 35°C, for example.

C. Resistance to Convective Heat

The amount of time for the heat from a gas flame (80Kw/kvm) to increase the temperature of the glove’s inside material by 24°C is measured.

D. Resistance to Radiant Heat

The glove’s material is stretched in front of a heat source with an effect of 20-40 kw/kvm. The average time is measured for heat penetration of 2.5 kw/kvm.

E. Resistance to Small Splashes of Molten Metal

The test is based on the number of small molten metal droplets dropped on the outside of a glove required to raise the temperature on the inside by 40°C.

F. Resistance to Large Splashes of Molten Metal

Simulated skin is attached to the inside of the glove material. Molten metal is then poured over the glove material.

The total number of grams of molten metal required to damage the simulated skin is measured.
All products submitted must achieve at least level 1 when tested for abrasion and tear in accord with methods in EN 388.
Contact Heat (B): Burning behaviour must attain level 3 at least for contact heat values of 3 or 4 to be reported; otherwise, a maximum of level 2 must be reported irrespective of whether the actual result if higher.
Convective Heat (C), Radiant Heat (D), Small Metal Splash (E): no results can be reported unless at least level 3 or 4 is achieved in the burning behaviour test
