--- Modified classification and marking;

--- Modify the working pressure;

--- Modify the metal thermal strength value;

--- Increased heat dissipation requirements;

--- Modify the casting quality requirements;

--- Modify the machining quality requirements;

--- Modify the test method of the inner cavity without sand;

--- Increased coating quality requirements;

--- Increased assembly requirements;

--- Revised inspection item list;

--- Revised inspection sampling plan.

1 Scope

This standard specifies the terms and definitions, classification and marking, requirements, test methods and inspections for cast iron heating radiators (hereinafter referred to as radiators). Rules, signs, packaging, transportation and storage.

This standard applies to heating systems for industrial and civil buildings, with hot water not exceeding 130°C and steam not exceeding 0.2 MPa. Steam as a heat medium cast iron radiator.
