标准摘要
[中文适用范围]: IEC 62788 的这一部分定义了表征光伏 (PV) 模块或系统中使用的聚合物成分材料耐候性的测试程序。本文中的方法主要集中在聚合物背板和密封剂上,但也可以应用于其他材料;然而,这些并没有作为准备工作的一部分得到验证。本文件包括一套人工老化暴露,包括模拟太阳辐照度、温度和湿度条件的稳态应用,通过老化测试保持在稳定水平。循环应力,包括热循环和湿/干循环,留给未来的规范。本文件中的内容旨在供其他标准参考,并作为支持光伏组件和模块的研究和产品开发的工具。不同的暴露可用于针对特定的气候/安装配置,以及如何应用暴露的细节留给这些标准(例如组件特征标准、模块资格标准)。提供了一份资料性附件作为参考,其中包括用于开发暴露套件的一系列气候/应用配置的参数描述。 [外文原描述]: IEC TS 62788-7-2:2017(E) defines test procedures to characterize the weatherability of polymeric component materials used in photovoltaic (PV) modules or systems. The methods in this document have been focused on polymeric backsheets and encapsulants, but may be applied to other materials; however, these were not verified as part of the preparation. Exposures in this document are intended for reference by other standards and as a tool to support research and product development for PV components and modules. Different exposures may be used to target specific climate/mounting configurations, with the specifics of how to apply the exposures left to those standards (e.g. component characterization standards, module qualification standards).
