Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Environmental
Engineering (EE).
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 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-part 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, transportation 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.

1 Scope
The present document defines the classes of environmental conditions and their severities to which telecommunications
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 lining up;
- repair, maintenance and restoration of functions failed.

3 Definitions
For the purposes of the present document, the following terms and definitions apply:
absolute humidity: mass of water vapour in grammes which is associated with one cubic metre of dry air in an
air/water vapour mixture
NOTE: It is not intended for portable use but short periods of handling during erection work, down time,
maintenance and repair at the location are accepted.
relative humidity: ratio of the partial pressure of the water vapour in moist air at a given temperature, to the partial
pressure of the water vapour in saturated air at the same temperature
stationary use: equipment permanently placed at a certain site

6 ETSI EN 300 019-1-8 V2.1.4 (2003-04)
weatherprotected location: location at which the equipment is protected from direct weather influences
NOTE 1: Totally weatherprotected location: direct weather influences are totally excluded.
NOTE 2: Partly weatherprotected location: direct weather influences are not completely excluded.
