UL 1316 Ed. 3-2018

Standard for Fibre Reinforced Underground Tanks for Flammable and Combustible Liquids - Published Date: May 9, 2024

The Third Edition of UL/ULC 1316 has been issued to reflect the latest ANSI and SCC approval dates, and to incorporate the proposal dated January 19, 2018. The new and revised requirements are substantially in accordance with Proposal on this subject dated January 19, 2018. 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-biofuels 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 (for which the test fuels in Appendix A are not considered to be sufficient or applicable) that can be demonstrated or determined to be compatible with the reinforced plastic underground tank materials as determined by the certifier.
