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

Part 1 specifies different standardised environmental classes covering climatic and biological

conditions, chemically and mechanically active substances and mechanical conditions during

Part 2 specifies the recommended test severities and test methods for the different environmental

Part 2-0 forms a general overview of Part 2. This part, (Part 2-4), deals with stationary use at non-

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].

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

The detailed descriptions of the environmental conditions are given in Clauses 4 and 5 of

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,
