The present document defines classes of environmental conditions and their severities to which telecommunication
equipment may be exposed. The severities specified are those which will have a low probability of being exceeded;
generally less than 1 % of the operating time in a year.
The present document applies to equipment mounted for stationary use including periods of erection work, down time,
maintenance and repair at weatherprotected locations defined in clause 5.
