Welding activities - ISO 11611:2015

Clothing to protect against the risks associated with welding activities

This standard specifies the minimum safety requirements and testing methods for protective clothing to be worn while welding.

Welder clothing must be designed to protect the wearer against small splashes of molten metal and radiant heat from the arc used. It must also be designed to reduce the possibility of electric shock through short, accidental contact with an electric conductor at a voltage of around 100 V DC or less under normal welding conditions.

Welder clothing must also protect the wearer against short-term contact with a flame, which is why it is also compliant with ISO 11612 (Protection against heat and flames).

Performance requirements:

• Class 1: Protection against welding techniques with low-level exposure to splashes and radiant heat (infrequent welding).
• Class 2: Protection against welding techniques with high-level exposure to splashes and radiant heat (frequent welding).

Please note:
For Category 3 PPE, a top and bottom of equivalent protection must be worn.
Dirt, sweat and other contaminants will reduce protective performance.
