This specification provides the material requirements, construction, installation, and testing requirements for molded and pultruded fiber reinforced plastic (FRP) gratings used in the marine environment. The purpose of this specification is to ensure that all FRP gratings are designed and tested appropriately to ensure personnel safety. This specification is intended for use by all persons planning, designing, manufacturing, testing, purchasing, inspecting, and maintaining FRP gratings. Limitations - This guide does not constitute regulations or ship classification rules, which must also be consulted where applicable.
FRP gratings have been used on U.S. Coast Guard inspected vessels, including mobile offshore drilling units and floating production platforms in place of steel gratings because they are light weight and resistant to corrosion. However, FRP gratings are combustible and exhibit mechanical properties different than steel and thus require testing for structural integrity and surface flammability, along with careful consideration of the long term effects of loading condition, moisture absorption, ultra-violet exposure, and oil/chemical exposure, typically experienced in the marine environment.
The title and scope are in draft form and are under development within this ASTM Committee.
