ISO 9459-5:2007规定了太阳能生活热水（SDHW）系统的室外实验室测试方法。该方法也可用于现场试验，也可用于室内试验，方法是为室内测量指定适当的引出剖面和辐照度剖面。系统性能的特点是采用“黑匣子”方法进行整个系统测试，即不需要对系统部件或系统内部进行测量。详细说明包括测量程序、测量数据的处理和分析以及测试报告的提交。

ISO 9459-5:2007 specifies a method for outdoor laboratory testing of solar domestic hot-water (SDHW) systems. The method may also be applied for in-situ tests, and also for indoor tests by specifying appropriate draw-off profiles and irradiance profiles for indoor measurements. The system performance is characterized by means of whole-system tests using a 'black-box' approach, i.e. no measurements on the system components or inside the system are necessary. Detailed instructions are given on the measurement procedure, on processing and analysis of the measurement data, and on presentation of the test report.
