EN 11612: protection against heat and flame
EN 175 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 EN 175 certification must have a minimum size of the field of vision to allow welding work to be carried out safely. In addition, the certification includes that all materials used must be opaque in internal parts to prevent light reflection during welding. Specifically, EN 175 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 EN 166 standardisation. The EN 175 standard also specifies something about the mechanical resistance of welding goggles and welding masks. EN 11612 is the European standard for workwear that protects the wearer against heat and flames. Please note that welding and firefighting clothing are not covered by this standard. Depending on the protection level, the wearer of the certified workwear is protected against exposure to heat or flames for a short period of time. The level of protection is divided into six protection categories (A to F), each representing a different type of heat. The number of performance levels (numbers) is noted in brackets after the category. The higher this number, the longer the workwear protects against heat.
A: limited flame spread
B: convection heat (1 to 3)
C: radiant heat (1 to 4)
D: liquid splashes of aluminium (1 to 3)
E: liquid splashes of iron (1 - 3)
F: contact heat (1 to 3)
n 'F' mark indicates low resistance of 45 m/s and 'B' mark indicates medium resistance of 120 m/s.
