各位大侠，一直在找EN60950-1:2006/A12:2011 的标准未果， 请教下此份标准中是否规定了产品工作环境的海拔高度和温度等条件？

海拔高度与温湿度影响的是设备的绝缘性能，可以查一下Clearence and Creepage那里应该会有提到2000m以下。2000m以上需要相应提高clearence和creepage的距离

就中国的GB4943新版对海拔做了要求，其他标准没做要求的！

2.10.3.1第三段有提到如果海拔超过2000m，则要参考iec60664-1。

These requirements apply for equipment to be operated up to 2 000 m above sea level. For
- j; j* ?/ j/ ]9 g/ }& [2 nequipment to be operated at more than 2 000 m above sea level, the minimum CLEARANCES
