STANDARD FOR FIBRE REINFORCED PLASTIC UNDERGROUND TANKS FOR FLAMMABLE AND COMBUSTIBLE LIQUIDS - Third Edition
 N CAN/ULC-S615-14

Annotation

This Standard sets forth minimum design and construction requirements for fibre reinforced plastic, non-pressure tanks that are used for the underground storage of flammable and combustible liquids, such as:

A Petroleum products, including petroleum hydrocarbon fuels with low bio-blends, per specifications, and similar flammable or combustible liquid petroleum derivatives, such as fuel components (cetane, hexane, heptane), and oils (lubricating, hydraulic, machine);

B Oxygenated fuel blends, including all petroleum product liquids; plus petroleum hydrocarbon fuels with low-biofuels blends;

C Oxygenates, including all "petroleum product" and oxygenated fuel blends liquids; plus pure/ denatured or highest oxygenated blend stocks for use in mixing of dispensed lower fuel-blends and components, such as biodiesel and ethanol; and

D Other flammable and combustible liquids that can be demonstrated to be compatible with the reinforced plastic underground tank materials.

NOTE: Refer to Appendix A (Informative) for a list of Standards on fuels and other flammable and combustible liquids.

This Standard covers tanks of either single, double or multiple wall construction.

NOTE: Tanks covered by these requirements are generally cylindrical or spherical in shape.

Tanks covered by this Standard are fabricated, inspected, and tested for leakage and structural strength prior to shipment from the factory as completely assembled vessels.
