EN11611

Protective clothing for welding and related processes
Clothing produced according to EN ISO 11611 serves to protect the wearer while welding or performing allied processes involving comparable risks. This clothing provides protection against spatter (minor splashes of molten metal) and so-called welding beads as well as brief contact with flames and radiant heat from the arc.Under normal welding conditions, it offers limited electrical insulation against DC voltage of up to approximately 100 V.
According to EN ISO 11611, the clothing is divided into the following classes depending on their level of protection:
Class 1 = protection against less hazardous welding techniques and situations causing lower levels of spatter and radiant heat
Class 2 = protection against more hazardous welding techniques and situations causing higher levels of radiant heat.
