GB/T 13754-2008 in English

《GB/T 13754-2008采暖散热器散热量测定方法》由TC143（全国暖通空调及净化设备标准化技术委员会）归口，主管部门为住房和城乡建设部。
本标准于1992年首次发布。
本标准代替GB/T 13754-1992《采暖散热器散热量测定方法》。
本标准规定了采暖散热器散热量测定的术语与定义、符号与单位、测试对象的选择、测试原理、测试装置布置、测试方法和测试报告内容。
本标准适用于热媒为水（热媒温度低于当地大气压力下水的沸点温度），由远程热源提供热量的散热器的标准散热量的测定；测试散热器的散热量不应小于700W，且对于每立平方米小室体积散热量不大于87W。
热媒为水（热媒温度不超过当地大气压力下水的沸点温度）或蒸汽时，散热器散热量可参照本标准进行测定。
本标准不适用于自带热源散热器。
本标准与GB/T 13754-1992相比主要技术内容变化如下：
――检测对象扩展到整个散热器类，特征公式中引入特征尺寸和流量；
――规定各个检测实验室应配置自己的标准散热器；
――与原标准相比，对检测过程的稳态条件做了更严格的规定；
――增加了金属热强度术语及计算方法。

Scope

This standard specifies the terms and definitions, symbols and units, selection of test objects, test principles, test device layout, test methods and test report content for the measurement of heating radiator (hereinafter referred to as radiator). This standard is applicable to the determination of the standard heat dissipation of radiators with water as the heat medium (heat medium temperature is lower than the boiling point of water under local atmospheric pressure), and the heat is provided by a remote heat source; the heat dissipation of the test radiator should not be less than 700W, and For the heat dissipation of each cubic meter of the small chamber is not more than 87W. When the heat medium is water (the temperature of the heat medium exceeds the boiling point of water under the local atmospheric pressure) or steam, the heat dissipation of the radiator can be measured by referring to this standard. This standard does not apply to radiators with their own heat sources.
