This specification covers material, design, fabrication, and testing requirements for fiberglass-reinforced plastic (FRP) tanks. Only shop-fabricated, vertical, cylindrical tanks are covered. Tanks covered by this specification are intended for aboveground and atmospheric pressure service. Unsupported cone bottom tanks are outside the scope of this specification. This specification is designed to provide the petroleum industry with various standard sizes of FRP tanks.
Because of the versatility of FRP tanks, the user shall be responsible for determining the suitability of FRP tanks for the intended service. NOTE The consequences of exposing FRP tanks to high temperatures created by exposure fires should be considered. This material loses strength as the temperature increases. FRP tanks should be suitably protected against fire exposure or so located that any spills resulting from the failure of these materials could not unduly expose persons, buildings, structures, or other equipment to the possible fire incident.
