EN ISO 11612:2008

Protection against heat and flames

This standard makes it possible to assess the level of performance of protective clothing for the body (with the exception of the hands) against heat and/or flames.

The person equipped with EN ISO 11612:2008 standardized clothing is protected in case of brief contact with a flame as well as against heat emitted by convection and by radiation (to a certain extent).

EN ISO 11612 has replaced the EN 531 standard.

The performance requirements guaranteed by this standard are applicable to a large range of clothing items having several types of end uses.
The standardized clothing offer limited flame spread properties and tolerance to exposure to heat emitted by radiation, convection, through contact or due to spraying/splashing of molten metal.

The performances of the ISO 11612:2008 standard are as follows:
The higher the numerical index, the greater will be the protective performance.

A: Minimum protective performance with respect to flame spread (A1 and/ or A2)
B: Performance with respect to insulation against convective heat (B1< B3)
C: Performance with respect to insulation against heat radiated (C1<C4)
D: Performance with respect to insulation against aluminium spraying (D1<D3)
E: Performance with respect to insulation against cast iron spraying (E1<E3)
F: Performance with respect to insulation against heat through contact (F1<F3)
