Specifications of level numbers and requirements relating to the transmittance of filters to protect operators for welding and related techniques.
Specification of requirements for welding filters with double number of levels.

This table is valid under normal conditions of use, in which the distance between the eye of the user and the mass of molten metal is approx. 50 cm and average light is approx. 100 lux.
