9、to the present document. Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Environmental Engineering (EE). The present document consists of 2 parts as follows: Part 1:“Classification of environmental conditions“. NOTE 1: Specifies different sta
10、ndardized environmental classes covering climatic and biological conditions, chemically and mechanically active substances and mechanical conditions during storage, transportation and in use. Part 2:“Specification of environmental tests“. NOTE 2: Specifies the recommended test severities and test me
11、thods for the different environmental classes. Each part of the standard is divided into sub-parts. Sub-part 2-0 forms a general overview of Part 2. This sub-part 2-8 deals with stationary use at underground locations. National transposition dates Date of adoption of this EN:3 September 1999 Date of
12、 latest announcement of this EN (doa):31 December 1999 Date of latest publication of new National Standard or endorsement of this EN (dop/e):30 June 2000 Date of withdrawal of any conflicting National Standard (dow):30 June 2000 ETSI ETSI EN 300 019-2-8 V2.1.2 (1999-09)5 1Scope The present document
13、specifies test severities and methods for the verification of the required resistibility of equipment according to the relevant environmental class. The tests in sub-part 2-8 of this multi-part EN apply to stationary use of equipment at underground locations covering the environmental conditions sta
14、ted in ETS 300 019-1-8 1. 2References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non- specific. For a spec
15、ific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the same number. 1ETS 300 019-1-8: “Equipment Engineering (EE); Environmental conditi
16、ons and environmental tests for telecommunications equipment; Part 1-8: Classification of environmental conditions; Stationary use at underground locations“. 2IEC 60068-2: “Basic environmental testing procedures - Part 2: Tests“. 3ETS 300 019-2-0: “Equipment Engineering (EE); Environmental condition
17、s and environmental tests for telecommunications equipment; Part 2-0: Specification of environmental tests; Introduction“. 3Environmental test specifications The detailed descriptions of the environmental conditions are in clauses 4 and 5 of ETS 300 019-1-8 1. ETS 300 019-2-0 3 forms a general overv
18、iew of Part 2 of the present document. 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 needs to be specified in the product specification. Inpu
19、t and load conditions of the equipment shall be chosen to obtain full utilization of the equipment under test. The heat dissipation shall be maximized, except for the steady state low temperature test, where it shall be minimized. 3.1Specification T 8.1: Partly weatherprotected underground locations
20、 This specification applies to underground enclosures in footway boxes, manholes and some tunnels etc. which are protected from direct weather influences. The location has no temperature or humidity control, but the variations in the temperature are limited due to the stabilizing influence of the su
21、rroundings. The equipment may be immersed in water during exceptional conditions.
