Scope

This standard specifies the terminology, structural forms, designations, requirements, test methods, inspection rules, markings, packaging, transportation, and storage of safety valves for electric water heaters (hereinafter referred to as safety valves). This standard applies to safety valves installed on the water inlet pipelines of electric water heaters. The pressure of the water supply system is 0.025 MPa to 10 MPa, and the safe discharge pressure of the safety valves is: 06 MPa to 09 MPa for closed-type valves, and 015 MPa to 035 MPa for open-type valves. The medium temperature shall not exceed 90℃.
