EN175: Eye and face protection when welding

EN175 is the general European standard for personal protective equipment used for eye and face protection in welding and similar processes, such as cutting work. Eye and face protection with EN175 certification must have a minimum size of the field of vision to allow welding activities to be performed safely. In addition, the certification includes that all materials used must be opaque in internal parts to prevent light reflection during welding. Specifically, EN175-certified PPE protects against splashes of molten metal and other solid hot substances. This is an optional test indicated by a '9' marking on the product. A complete overview of optional protection can be found in the general EN166 standardisation. The EN175 standard also indicates something about the mechanical resistance of welding goggles and welding masks. An 'F' marking indicates a low resistance of 45 m/s and a 'B' marking indicates a medium resistance of 120 m/s.
