Chemical Protective Suits = Personal Protective Equipment

Chemical protective suits prevent adverse health effects from working in chemically or microbiologically contaminated environments.

Each chemical protective suit is designed for a specific use, as resistance to all substances and materials from every environment is not possible.

Depending on the type of use, there are 6 types or protection levels for chemical protective suits, which differ in their protective effect from gas-tight to limited tightness against liquids.

We check whether disposable, limited-use or reusable chemical protective clothing meets:

  • The specifications of the European personal protective equipment (PPE) standard DIN EN 14325
  • Type-specific requirements

Testing and Certification of Protective Clothing against Chemicals

As an accredited laboratory and notified body (No. 0555), we:

  • Test and certify chemical protective suits in accordance with the requirements of DIN EN 14325
  • Issue EU type examination certificates for CE marking of products in accordance with Regulation (EU) 2016/425


  • Independent functional verification of your products
  • Reliable safety for the protective suit consumer/user and brand
  • Compliance with all European market requirements (Regulation (EU) 2016/425) and CE mark for PPE
