PROTECTION CLOTHES FOR PROTECTION AGAINST HEAT AND FLAMES

scope of application
This standard defines the performance requirements for clothing made of flexible materials and intended to protect the body (except the hands) from heat and / or flames. The performance requirements apply to numerous applications where limited flame propagation may occur or where the carrier is exposed to radiant heat, convective heat, contact heat, or spattering of molten material.

The code letter A in the pictogram
The code letters indicate the fulfilled class: the higher the class, the higher is the guaranteed protection.

CLASSIFICATION

Code letter A: Flame of materials and seams according to EN 15025
A1: Surface flaming 10 seconds A2: Edge flaming 10 seconds

Code letter B: Protection against convective heat (ISO 6151)
This higher class provides protection against more hazardous welding processes and defined flaming of the upper side of the material, determining how long it takes for the temperature at the rear to rise by 24 ° C (2nd degree burn). B1 to B3.

Code letter C: Protection against radiant heat (ISO 6942 Method B)
It is determined how long it takes for a second-degree combustion to occur when the material is subjected to a heat radiation of 20 kW / m 2. C1 to C4.

Code letter D: Protection against liquid aluminum (ISO 9185)
The minimum quantity of liquid aluminum is poured onto the material. After four consecutive tests, a PVC film (simulated skin) on the underside must not be damaged. D1 to D3.

Code letter E: Protection against liquid iron (ISO 9185)
The minimum amount of liquid iron is poured onto the material. After four consecutive tests, a PVC film (simulated skin) on the underside must not be damaged. E1 to E3.

Code letter F: Contact heat (ISO 12127)
Test for protection against contact heat at a temperature of 250 ° C. F1 to F3.

Protective clothing conforming to this standard shall meet the requirements for the limited flame spread (code letter A) and at least one of the code letters for heat transfer (code letters B to F).
