ISO 14934-2:2006描述了三种校准总半球辐射计和总热流计的方法，这些辐射计和总热流计暴露在辐射热源的明确辐射下。该设备旨在将校准过程中对流传热的影响降至最低。值得注意的是，在实际使用这些仪器时，它们会测量辐射和对流传热的组合。后者将取决于热流计的设计、方向、局部温度和流量条件，以及冷却水的温度。

ISO 14934-2:2006 describes three methods for calibration of total hemispherical radiometers and total heat flux meters that are exposed to a well-defined radiation from a radiant heat source. The equipment is designed to minimize influences due to convective heat transfer during calibration. It is important to note that when the instruments are used in practice they measure a combination of radiant and convective heat transfers. The latter will depend on the design of the heat flux meter, the orientation, local temperature and flow conditions, and on the temperature of the cooling water.
