BS EN 379:1994 : Specification for Welding filters with switchable luminous transmittance and welding filters with dual luminous transmittance
Printed version of this standard is available at Library. To request, please e-mail to referencepk@usm.my and include a copy of this record in your e-mail.
This standard specifies requirements for welding filters which automatically switch their luminous transmittance to a lower value when a welding arc is ignited (referred to as welding filters with switchable scale numbers). The requirements of this standard apply if such a filter is to be used for continuous viewing of the welding process and if it is to be used only during the period when the arc is being ignited.
