GB/T 13754-2008

This standard specifies the terms and definitions, symbols and units, selection of test objects, test principles, test device arrangement, test methods, and test report content for the determination of the heat dissipation of heating radiators (hereinafter referred to as radiators).
This standard applies to the determination of the standard heat dissipation of radiators that are supplied with heat by a remote heat source and use water as the heat medium (with a temperature lower than the boiling point of water under local atmospheric pressure); the heat dissipation of the tested radiators should not be less than 700 W, and for each cubic meter of small chamber volume, the heat dissipation should not exceed 87 W.
When the heat medium is water (with a temperature exceeding the boiling point of water under local atmospheric pressure) or steam, the heat dissipation of the radiators can be measured in accordance with this standard.
This standard does not apply to radiators with their own heat sources.
