EN60950-1:2006/A12:2011标准中是否规定工作环境的海拔高度？

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

or explosive atmospheres);
− electromedical applications with physical connections to the patient;
− equipment intended to be used in vehicles, on board ships or aircraft, in tropical countries,
or at altitudes greater than 2 000 m;− equipment intended for use where ingress of water is possible; for guidance on such

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
equipment to be operated at more than 2 000 m above sea level, the minimum CLEARANCES
shall be multiplied by the factor given in Table A.2 of IEC 60664-1. Linear interpolation is
permitted between the nearest two points in Table A.2.
