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).
ETS 300 019 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".
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".
Part 2 specifies the recommended test severities and test methods for the different environmental
classes.
Part 2-0 forms a general overview of Part 2. This part, (Part 2-4), deals with stationary use at non-
weatherprotected locations.

1 Scope
This European Telecommunication Standard (ETS) specifies test methods and severities for verification
of the required resistibility of equipment according to the relevant environmental class.
The tests defined in Part 2-4 of this multi-part standard apply to stationary use of equipment at non-
weatherprotected locations covering the environmental conditions stated in ETS 300 0191-4 [1].
2 Normative references
This ETS incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest
edition of the publication referred to applies.
[1] ETS 300 0191-4: "Equipment Engineering (EE); Environmental conditions and
environmental tests for telecommunications equipment Part 1-4: Classification
of environmental conditions; Stationary use at non-weatherprotected locations".
[2] IEC 68-2: "Environmental testing: Part 2: Tests".
[3] ETS 300 0192-0: "Equipment Engineering (EE); Environmental conditions and
environmental tests for telecommunications equipment Part 2-0: Specification of
environmental tests; Introduction".
3 Environmental test specifications
The detailed descriptions of the environmental conditions are given in Clauses 4 and 5 of
ETS 300 0191- 4 [1].
ETS 300 0192-0 [3] forms a general overview of Part 2 of this ETS.
The equipment under test is assumed to be in its operational state throughout the test conditions
described in this Part unless otherwise stated. The required performance before, during and after the test
need to be specified in the product specification. Input and load conditions of the equipment shall be
chosen to obtain full utilisation of the equipment under test. The heat dissipation shall be maximised,
except for the steady state, low temperature test, where it shall be minimised.
