IEC 62109-1 规定户外产品外壳上的塑料件必须足够 耐 紫外线
/ m/ G1 r( G8 V* N" \) O3 C7 W: S' b" R! P- ]/ s" s6 Z

又说符合性通过检查塑料的 耐UV data来判定。

那啥样的data算合适的? 在UL 塑料查询网页里, 有一个 (f1) = Suitable for outdoor use with respect to exposure to Ultraviolet Light, Water Exposure and Immersion in accordance with UL 746C.
1 H, T. s |, \, i, h7 i2 \! }9 }选项, 选中此后得到的塑料是否都可以认为是 data合适的?. O/ p& [1 H1 H4 |. i' k4 c

另,如果户外外壳的绝大部分是钣金结构,只有局部窗口区域是塑料件覆盖, 这个局部的塑料件也要 保证耐UV么? |
