What are the protection standards for welding work?
EN169 WELDING FILTERS
Specifies the scale numbers and requirements relative to the transmission factor of filters designed to protect operators carrying out work involving welding, hard soldering, arc gouging using compressed air and plasma stream cutting. It also includes requirements relative to dual scale number welding filters.
EN379 VARIABLE OR DUAL SCALE WELDING PROTECTION FILTERS
EN379 specifies the requirements relating to welding filters which automatically switch their transmission factor in the clear zone to a lower value when a welding arc is struck (known as welding filters with switchable scale numbers). The specifications of the standard apply if such a filter is to be used for the continuous observation of the welding process and if it is only used during the period where the arc is ignited. The standard also specifies the requirements for welding filters with different welding scale numbers in the clear zone (called welding filters with a double scale number). These filters are used for welder protective eyewear or system-mounted protection.
EN175 WELDING GOGGLES AND EQUIPMENT
This European standard specifies the requirements and test methods related to personal protective equipment used to protect the operator’s eyes and face against harmful optical radiation and other specific risks due to customary welding or cutting processes or other associated techniques. The standard specifies protection, including ergonomic aspects, against various risks or hazards including radiation, fire, mechanical and electrical risks. This standard defines the terms used and specifies the requirements related to materials, design and manufacture.
