EN ISO 11611 (protective clothing for welders)

EN ISO 11611 sets requirements for protective clothing for welding and allied processes. It protects against accidental brief contact with small ignition flames and against weld spatter, but not where there is a significant heat hazard. There are two classes: class 1 for less hazardous processes, class 2 for processes with more weld spatter and stronger radiant heat. In Germany, DIN EN ISO 11611:2015-11 applies.

When is this relevant?

Relevant for welders, flame cutters and employees in the immediate vicinity of welding work. The standard covers only the clothing. Additional protective equipment under other standards must be worn for head, face, hands and feet. Where there is a heat hazard, welders' clothing is often combined with EN ISO 11612.

Classes

  • Class 1 (lower class): protection for less hazardous welding processes and situations with less weld spatter and lower radiant heat
  • Class 2 (higher class): protection for more hazardous welding processes and situations with more weld spatter and stronger radiant heat

The class is chosen according to the hazard at the workplace. The risk assessment is decisive.

Status of the standard

DIN EN ISO 11611:2015-11 applies in Germany. The international ISO 11611 has been available in a new edition since June 2024. When checked on 02.11.2026, no German version of this edition was yet listed at DIN Media.

Combination with other standards

Welders' clothing often also carries markings to EN ISO 11612 for heat and flames and to EN 1149-5 for antistatic properties, for example in the CWS welding protection collection Alpha Welding 2 with class 2.
