Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Environmental
Engineering (EE).
The present document is part 1, sub part 4 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"; (see note 1)
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". (see note 2)
NOTE 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. Sub-part 1-0 forms a general overview of part 1.
NOTE 2: Specifies the recommended test severities and test methods for the different environmental classes.

1 Scope
The purpose of the present document is to define a class of environmental conditions and their severities to which
equipment may be exposed. Only severe conditions, which may be harmful to the equipment, are included. The
severities specified are those which will have a low probability of being exceeded; generally less than 1 %.
The present document applies to equipment mounted for stationary use including periods of erection work, down time,
maintenance and repair at non-weatherprotected locations defined in clause 5.

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
non-weatherprotected location: location at which the equipment is not protected from direct weather influences
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: The equipment is mounted firmly on the structure, or on mounting devices, or it is permanently placed
at a certain site. It is not intended for portable use - but short periods of handling during erection works, down time,
maintenance and repair at the location are included.
4 Environmental classes
The classes shown in parentheses, e.g. (4C3), may be selected for special applications.
These classes apply to a non-weatherprotected location.
These classes apply to locations:
- which are directly exposed to an open-air climate, including solar radiation, movement of the surrounding air,
precipitation and water jets; splashing water;
- where mould growth, or attacks by animals but excluding termites, may occur;
- with normal levels of contaminants experienced in urban areas with industrial activities scattered over the
whole area and/or with heavy traffic. It also applies to coastal areas;
NOTE 1: At locations in the immediate neighbourhood of industrial sources with chemical emissions either special
precautions must be taken or a special chemical class must be chosen.
- in areas with sand or dust sources, including urban areas;
NOTE 2: At locations in geographical areas with wind-driven sand or dust in air special precautions must be taken
or a special class for mechanically active substances must be chosen.
- where transmitted vibrations are experienced from machines or passing vehicles. Higher level shocks may be
experienced e.g. from adjacent machines.
NOTE 3: More severe mechanical conditions are to be expected for equipment intended for public use. Special
requirements should be stated for such equipment, e.g. protection against vandalism.
If earthquake conditions can be expected, the conditions stated in clause 5.6 apply.
Two groups of classes are considered:
- Classes 4.1 and 4.1E apply to general climatic conditions - applies to climatic conditions in most of Europe.
- Classes 4.2L and 4.2H apply to extreme climatic conditions. These classes should be considered
