EN175, standard for welding hoods

Specifies safety requirements and test methods related to the eye and face protective equipment used for welding and associated techniques. This European standard specifies the requirements and test methods related to the 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 the risks or hazards of various kinds: radiation, inflammability, mechanical and electrical risks. This standard defines the terms used and specifies the requirements related to materials, design and manufacture.

EN379, standard for welding filters

EN379 belongs to a series of European standards drafted by the European Standardization Committee (ESC) within the scope of the application of the European Directive on Personal Protective Equipment (PPE). It specifies the requirements related to welding filters which automatically switch their transmission factor in the visible to a lower value when a welding arc is ignited (qualified welding filters with numbers of switchable levels). 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 factor areas in the visible (called welding filters with a double number of levels). These filters are used for the protectors of welder eyes or fixed to an installation.
