标准范围

IEC 62938:2020提供了一种确定框架光伏组件在倾斜非均匀雪荷载影响下机械性能的方法。本文件适用于框架模块，其框架在预期安装后伸出前玻璃表面的下边缘，因此为雪从模块上滑下创造了额外的屏障。对于具有其他框架结构的模块，如框架中形成的后导轨、侧边、上边缘和下边缘上未形成额外雪滑屏障的模块，本文件不适用。该试验方法确定了框架光伏组件的机械非均匀负载极限。

IEC 62938:2020 provides a method for determining how well a framed PV module performs mechanically under the influence of inclined non-uniform snow loads. This document is applicable for framed modules with frames protruding beyond the front glass surface on the lower edge after intended installation and as such creates an additional barrier to snow sliding down from modules. For modules with other frame constructions, such as backrails formed in frames, on the side edges, on the top edge and on the lower edge not creating an additional snow slide barrier, this document is not applicable. The test method determines the mechanical non-uniform-load limit of a framed PV module.
