This standard specifies the energy efficiency levels, technical requirements and test methods of industrial boiler products. This standard applies to stationary boilers that use coal, natural gas, oil, or biomass as fuel or electricity as heat source and water or organic heat carrier as medium: a) Steam boilers with rated steam pressure ≥0.1 MPa and <3.8 MPa; b) Hot water boilers with rated outlet pressure ≥ 0.1 MPa and rated power ≥ 0.1 MW; c) Organic heat carrier boilers with rated medium outlet pressure ≥ 0.1 MPa.
