EN ISO 11611:2007

Protection against spraying of molten metal

This standard makes it possible to assess the level of performance of protective clothing designed for protecting the user during welding processes or related techniques.

The EN ISO 11611:2007 standardized clothing are designed for use in a work environment where the user is subject to a risk of spraying of metal, of brief contact with a flame, radiant heat or an electric arc (welding or other related activities).

These clothing minimize the possibility of an electric shock through brief accidental contact with electric conductors which are powered.

The performances of the EN ISO 11611:2007 standard are divided between the following two classes: the higher the numerical index, the greater the protective performance.

Class 1: Requirement for minimum performances of protection during brief contact with a flame, radiant heat or an electric arc.
Class 2: Requirement for higher performances for protection during brief contact with a flame, radiant heat or an electric arc.

The standard specifies two test methods for determining the inflammability of the clothing:

A1: The clothes are compliant with the performances required for limited flame spread in case of fire on the surface
A2: The clothes are compliant with the performance required in case of fire in the surrounding areas
