Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Environmental Engineering (E
12、E). The present document is part 1, sub-part 8 of a multi-part deliverable covering the classification of environmental conditions and environmental tests for telecommunications equipment, as identified below: Part 1: “Classification of environmental conditions“; Sub-part 0: “Introduction“; Sub-part
13、 1: “Storage“; Sub-part 2: “Transportation“; Sub-part 3: “Stationary use at weatherprotected locations“; Sub-part 4: “Stationary use at non-weatherprotected locations“; Sub-part 5: “Ground vehicle installations“; Sub-part 6: “Ship environments“; Sub-part 7: “Portable and non-stationary use“; Sub-par
14、t 8: “Stationary use at underground locations“; Part 2: “Specification of environmental tests“. Part 1 specifies different standardized environmental classes covering climatic and biological conditions, chemically and mechanically active substances and mechanical conditions during storage, transport
15、ation and in use. Part 1-0 forms a general overview of part 1. Part 2 specifies the recommended test severities and test methods for the different environmental classes.

17、nications equipment may be exposed. The severities specified are those which will have a low probability of being exceeded; generally less than 1 %. The present document applies to equipment installed for stationary use at underground locations during: - normal operation; - on site installation and
18、lining up; - repair, maintenance and restoration of functions failed. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication and/or edition number
19、or version number) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.
