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