IEC TS 62862-3-3:20 20规定了太阳能热接收器的技术要求、测试、耐久性和技术性能参数，用于吸收集中的太阳辐射并将热量传递给具有线性聚焦太阳能集热器的聚光太阳能热电厂中使用的流体。所述接收器由吸收管和绝缘玻璃封套管组成。 本文件包括技术特性的定义、几何和性能参数的表征以及光学表征、热损失和耐久性的测试方法。为了清楚起见，本文中描述的热损失测试不传递当接收器管安装在商业太阳能场中时接收器管的热损失。

IEC TS 62862-3-3:2020 specifies the technical requirements, tests, durability and technical performance parameters of solar thermal receivers for absorbing concentrated solar radiation and transferring the heat to a fluid used in concentrated solar thermal power plants with linear-focus solar collectors. The receivers addressed consist of an absorber tube and an insulating glass envelope tube.
This document includes the definitions of technical properties and characterization of geometry and performance parameters as well as the test methods for optical characterization, heat loss, and durability. For the sake of clarity, it is stated here that the thermal loss tests described in this document do not deliver the thermal loss of the receiver tubes when they are installed in commercial solar fields.
