PROTECTIVE CLOTHING FOR WELDING AND ALLIED PROCESSES
EN ISO 11611
The garment is marked with this pictogram. The pictogram includes the name of the international standard as well as the class indication (class 1 or class 2) and the indication of the flame test that was applied (A1 and/or A2).
A DISTINCTION IS MADE BETWEEN TWO PERFORMANCE CLASSES:
CLASS 1 (LOWER CLASS):
Protects in less risky welding operations and situations with few splashes and low radiant heat. Performance requirement: Resistance to at least 15 metal drops.
Heat transmission (radiation) RHTI 24 ≥ 7 seconds.
CLASS 2 (HIGHER CLASS):
Protects when welding in confined spaces and when working in forced positions. Performance requirement: Resistance to at least 25 metal drops.
Heat transmission (radiation) RHTI 24 ≥ 16 seconds
For comprehensive protection against all risks to which welders are usually exposed, PPE for head, face, hands and feet with appropriate standards should also be worn.
Contaminants such as dirt or sweat, but also other factors such as humidity can impair protection!
