求助，谁有EN60747-5-2的标准的解析

求助，谁有EN60747-5-2的标准？急用！！！谢谢！
或者哪位可以解释下。VDE的证书里，对光藕有项技术指标是"Climatic Category:40/100/21",求解：
1：Climatic Category的要求是什么？通过什么实验来能过这个要求？
2：经过Climatic Category:40/100/21"这个要求后，是不是可以不用考虑光藕的内部爬电距离了（表示它已经通过了加强绝缘的要求了）？

本人急，谢谢！

21:21 days
Number of days, the duration of test Ca (damp heat, steady state) at a relative humidity of 93% +2/-3% and an ambient temperature of 40°C, in accordance with IEC 60068-2-78.

在950中必须通过thermal cycling test才不考虑内部爬电距离
