Foreword
This multi-part European Telecommunication Standard (ETS) has been produced by the Equipment
Engineering (EE) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This standard is concerned with environmental conditions and environmental tests for telecommunications
equipment and comprises two main parts, each with subdivisions:
- ETS 300 019-1: "Classification of environmental conditions".
This part of the standard, Part 1, specifies different standardised environmental classes covering
climatic and biological conditions, chemically and mechanically active substances and mechanical
conditions during storage, transportation and in use.
- ETS 300 019-2: "Specification of environmental tests".
This part of the standard specifies the test requirements for the different environmental classes.
Each part of the standard is divided into sub-parts. Sub-part 1-0 will form a general overview of Part 1.
This sub-part, Sub-part 1-4, deals with stationary use at non-weatherprotected locations.
This part of the standard (Part 1) was submitted to Public Enquiry as prETS 300 019 Part B. The original
Part A is to be published as ETSI Technical Report ETR 035 entitled: "Equipment Engineering (EE);
Environmental engineering Guidance and terminology".
Annex A to this sub-part is informative.

1 Scope
The purpose of this sub-part 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 %.
For completeness the IEC grouping of open-air climates is given in Annex A.
This sub-part 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.
2 Normative references
This ETS contains, by dated or undated reference, provisions from other publications. For dated
references, subsequent amendments to, or revisions of any of these publications apply to this document
only when incorporated into it by amendment or revision. For undated references, the latest version of the
publication referred to applies.

and terminology".

3 Definitions
In this sub-part of this standard, the following definitions apply:
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.
Non-weatherprotected location: A location at which the equipment is not protected from direct weather
influences.
4 Environmental class
The classes shown in parentheses, e.g. (4C3), may be selected for special applications.
4.1 Class 4.1: Non-weatherprotected locations
Class 4.1E: Non-weatherprotected locations - extended
Class 4.1 applies to many ETSI countries. Class 4.1 E covers all ETSI countries.
Class 4.1 is a combination of classes 4K2/4Z5/4Z7/4B1/4C2(4C3)/4S2/4M5 in IEC Publication 721-3-4 [2].
Class 4.1E is a combination of classes 4Z5/4Z7/4B1/4C2(4C3)/4S2/4M5 in IEC Publication 721-3-4 [2]
and the climatic conditions are given in subclause 5.1.
This class applies to a non-weatherprotected location. The climatogram is shown in figure 1 in subclause
5.1.

ETS 300 019-1-4: February 1992
This class applies to locations:
- which are directly exposed to an open-air climate, including solar radiation, movement of the
surrounding air, precipitation and water jets;
- 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: 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;
- where transmitted vibrations are experienced from machines or passing vehicles. Higher level
shocks may be experienced e.g. from adjacent machines.
NOTE: 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.

NOTE 1:  In cloudless nights an object exposed to atmospheric radiation
will radiate more heat than it receives off the surface, compared
to the ambient air temperature. In practice (under extreme
conditions) the surface may come down to a temperature in the
order of 10 C to 20 C below ambient air temperature, when the
ambient temperature ranges from +20 C to 30 C. (For further
information see IEC Publication 721 2 4 [3]).
