1 Scope
This standard specifies the method of thermal performance test (including type approval test, acceptance test, arbitration test and operation test) of steam boiler and hot-water boiler with working pressure less than 3.8MPa; it also specifies that the test result is expressed in table form.
This standard is applicable to boilers manually or mechanically combusting solid fuel, those combusting liquid or gas fuels or those adopting electricity as thermal energy. It may be applicable to hot oil carrier boiler or that adopting garbage as fuel for reference. This standard is not applicable to heat recovery boiler.
