ULC 620

This National Standard of Canada covers minimum requirements for hose nozzle valves that are intended to be used to control the flow of flammable and combustible liquids, which are handled at temperature within the range of -40 °C to +50 °C at a working pressure of not less than 350 kPa. The hose nozzle valves are of the types used in the assembly of motor fuel dispensing equipment. They are of the automatic or manually operated type, to the exclusion of types operated wholly or partially by electricity.

Amendment 1 contains revisions to correct the requirements in Clause 3.4.2, which speaks of the materials for fluid confining parts use in a hose nozzle valve. This Standard is now being re-published to include Amendment 1 of the Third Edition of CAN/ULC-S620, and all users are advised to obtain this complete version.
