FM 4950:2007 (R2013)

Sets performance requirements for welding pads, welding blankets and welding curtains used as a means of preventing the ignition of combustibles during welding, cutting and other hot work operations. Welding pads, welding blankets and welding curtains will be evaluated on their ability to: prevent burn through of the material; provide adequate protection for adjacent combustibles; limit temperature transmission through the material; resist melting, dripping or deformation, maintain their flexibility, durability and structural integrity; and resist degradation from weathering.
