This specification provides the testing and performance requirements for fiber-reinforced polymer (FRP) gratings used in marine construction and shipbuilding to ensure personnel safety. It is intended for use by all persons designing, manufacturing, testing, inspecting, and maintaining FRP gratings. It does not address the ability of the gratings to support either moving or stationary equipment during or after a fire exposure, as well as hydrocarbon pool or jet fire exposures. This specification covers test requirements that must be met, namely: deflection limits, assembled grating ultimate failure, wheel loading, assembled panel impact resistance, skid resistance, durability, ultraviolet resistance, salt spray, surface flammability, and structural fire integrity.
