What is EN ISO 11611?
EN ISO 11611 is the international standard for protective clothing for use in welding and allied processes.
What does EN ISO 11611 provide protection against?
This international standard specifies minimum basic safety requirements and test methods for protective clothing for use in welding and allied processes (excluding hand protection). There are two classes with specific performance requirements.
Class 1 Level Protection
Class 1 is protection against less hazardous welding techniques and situations, causing lower levels of spatter and radiant heat.
Class 2 Level Protection
Class 2 is protection against more hazardous welding techniques and situations, causing higher levels of spatter and radiant heat.
What are the testing parameters for EN ISO 11611?
The EN ISO 11611: standard has the following parameters:
- Tensile Strength
- Tear strength
- Busting strength
- Seam strength
- Dimensional change
- Requirements of leather
- Limited Flame Spread (A1 + A2)
- Molten Droplets
- Heat Transfer (radiation)
- Electrical resistance
Are there any more requirements to consider for EN ISO 11611?
Yes, flaps pockets, rule pockets and tensile and tear strength.
In order to comply with EN ISO 11611 all external pockets must be flapped, except for side pockets below the waist which do not extend more than ten degrees forward of the seam.
A single rule pocket with an opening not greater than 75mm is permitted behind the side seam on one or both legs.
Tensile and Tear Strength
To meet EN ISO 11611 tensile strength must be at least 400N and tear strength must be at least 15N for class 1 and 20N for class 2.
