Multi-standard clothing (several protection standards in one garment)

Multi-standard clothing meets several protection standards at the same time, for example high visibility to EN ISO 20471, heat and flame protection to EN ISO 11612, welding protection to EN ISO 11611 and antistatic properties to EN 1149-5. It replaces several individual garments and is intended for work where different hazards come together. Which standards are needed for the application is determined by the risk assessment.

When is this relevant?

Relevant for example for welding and grinding work in plant areas, in industry with flying sparks or for work in areas with an ignition hazard. Each standard has its own classes, so all markings on the label must match the application.

Typical combinations of standards

  • DIN EN ISO 20471:2017-03: high visibility in classes 1 to 3
  • DIN EN ISO 11611:2015-11: welding and allied processes in classes 1 and 2
  • DIN EN ISO 11612:2015-11: heat and flames with code letters and levels
  • DIN EN 1149-5:2018-11: electrostatic dissipative clothing

Example from the range

According to the manufacturer, the Portwest Bizflame Rain is a multi-standard high-visibility rain jacket as personal protective equipment of category III. It protects against brief flame contact, electrostatic charge and light chemical splashes, meets EN ISO 20471 class 3 and has a removable, flame-retardant fleece lining.

What you should look out for

  • All required standards and classes must appear on the label
  • Observe care instructions and the permitted number of washes according to the manufacturer
  • The protective effect applies only to the tested garment in the intended combination, not to additional clothing worn over it

General requirements for protective clothing are governed by EN ISO 13688, which applies in addition to the individual standards.
