Protective Clothing for Use in Welding and Allied Processes
The International standard specifies minimum basic safety requirements and test methods for protective clothing for use in welding and allied processes (Excluding Hand Protection).
The International Standard Specifies two classes with specific performance requirements:
Class 1 is protection against less hazardous welding techniques and situations causing lower levels of spatter and radiant heat.
Class 2 is protection against more hazardous welding techniques and situations causing higher levels of spatter and radiant heat.
EN ISO 11611 requires that protective suits completely cover the upper and lower torso, neck, arms and legs. There are a number of other design requirements which must be followed to prevent molten droplets lodging anywhere on the garment.
Testing must be carried out on pre-treated components according to the manufacturers care label.
- Tensile Strength (must meet a minimum of 400N)
- Tear Strength (Must meet a minimum of 20N)
- Bursting Strength
- Seam Strength
- Dimensional Charge
- Requirements of Leather
- Limited Flame Spread (A1+A2)*
- Molten Droplets
- Heat Transfer (Radiation)
- Electrical Resistance
*This test must be carried out on the fabric and seams.
