EN 470-1 - Protective clothing for use in welding and allied processes - Part 1: General requirements

The standard specifies requirement for clothing intended to protect the user against small droplets of molten metal and short contact time with flame, and includes holing, insulation, Flame spread and burn time. The garment assemblies shall require at least 15 drops of molten metal to reach a temperature rise of 40 degrees. Limited flame spread is tested with a flame (test method EN 532). Furthermore the garment must be constructed so there is no risk for welding sparks to get stuck in pockets or seams.

EN 531 - Protective clothing for industrial workers exposed to heat and flame (excluding firefighters' and welders' clothing)

The standard specifies the performance requirements for protective clothing for workers exposed to heat and flame. It is designed to improve and ensure guidelines in EN470-1, and includes strict guidelines for features.

Limited flame spread (A) (Pass/Fail) is tested in accordance with a test method defined by EN 532. To pass the EN 531 requirements the clothing must also protect against at least one form of heat. The heat may be in the form of convective heat B (level B1-B5) according to EN 367, radiant heat C (level C1-C4) according to EN 366, molten aluminium splash (D) according to EN 373, molten iron splash (E) according to EN 373. HH products subjected to EN 531 are tested on radiant- and convective heat.

AS/NZS 4824 - Protective clothing for firefighters

Requirements and test methods for protective clothing used for wildland firefighting (ISO 15384:2003, MOD) (FOREIGN STANDARD). Adopts ISO 1534:2003 with national modifications to provide the minimum requirements and test methods for assessing protective clothing that is intended to be worn during wildland firefighting and associated activities, where there is a risk of heat and flame.
