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.
