Protective clothing for use in welding and allied processes

EN ISO 11611 iconEN ISO 11611

EN 11611 specifies material performance and design requirements for clothing developed to protect against heat and flame and welding. Essentially the welding version of EN 11612, this norm defines protection against ignition from various heat sources, such as open flames, molten iron splash and contact heat. In addition, garments certified according to EN 11611 protect against radiant heat from the arc as well as minimize the possibility of electrical shock by short-term, accidental contact with live electrical conductors.

EN 11611 features two classes, Class 1 and Class 2, depending on the type of welding technique used. Class 1 comprises less hazardous welding techniques and situations, lower levels of spatter (splashes of molten metal) and radiant heat, whereas Class 2 includes more hazardous welding techniques and situations, higher levels of spatter and radiant heat.

The norm also includes several design requirements, such as that suits should completely cover the upper and lower torso, neck, arms and legs, and that external pockets should be covered by flaps at least 20 mm wider than the opening of the pocket.
