19、flame propagating liquid tight sheathing systems for the protection and management of insulated conductors and/or cables in electrical installations or in communication systems up to 1 000 V a.c. and/or 1 500 V d.c. This standard applies to metallic, non-metallic and composite liquid tight sheathing
20、 systems including threaded fittings which terminate the system This European Standard does not apply to conduit systems for electrical installations which come within the scope of EN 50086 series as well as EN 61386 series. Liquid tight sheathing systems do not provide mechanical protection to insu

28、ising both metallic and non-metallic materials 3.7 non-flame propagating sheathing and/or terminating fitting sheathing or terminating fitting which is liable to catch fire as a result of an applied flame, but in which the flame does not propagate and which extinguishes itself within a limited time
29、after the flame is removed 3.8 external influence factors which may affect the sheathing system NOTE Examples of such factors are a presence of water, oil or building materials, low and high temperatures and corrosive or polluting substances. 4 General requirements 4.1 Liquid tight sheathing systems
30、 shall be so designed and constructed that in normal use their performance is reliable and they provide protection to the user to the user or surroundings. When assembled in accordance with manufacturers instructions, the liquid tight sheathing system, shall provide protection against ingress of liq
31、uids and electrical protection of the insulated conductors and cables contained therein. 4.2 Liquid tight sheathing and terminating fittings shall withstand the stresses likely to occur during transport, storage, recommended installation practice and application. 4.3 Compliance is checked by carryin
32、g out all the tests specified. 5 General conditions for tests 5.1 Tests in accordance with this standard are type tests. 5.2 Unless otherwise specified, the tests shall be carried out at an ambient temperature of (20 5) C. 5.3 Unless otherwise specified, each test shall be made on three new samples.
33、 NOTE Certain tests, for instance the checking of dimensions, do not affect a change in the property of the samples, therefore these samples are considered as new samples and can be used for further tests. 5.4 Samples of liquid tight sheathing and fittings shall be conditioned for at least 240 h, at
34、 a temperature of (23 2) C and a relative humidity between 40 % and 60 %. All tests shall be carried out immediately after general conditioning. EN 50369:2005 6 5.5 Unless otherwise specified, the samples for each test shall be in a clean and new condition, with all parts in place and mounted as in
35、normal use. After checking dimensions in accordance with Clause 8, and unless otherwise specified in the relevant test, the fittings shall be assembled with adequate lengths of liquid tight sheathing of the type for which they are intended. Due regard shall be taken of the manufacturers instructions
36、, especially where force is required in the assembly of the joint. NOTE Where similarities are claimed, the selection of representative fittings for test purposes can be agreed between the manufacturer, or responsible vendor, and the testing station 5.6 Unless otherwise specified, three samples are
37、subjected to the tests and the requirements are satisfied if the tests are met. If only one of the samples does not satisfy a test, due to an assembly or a manufacturing defect, that test and any preceding one which may have influenced the result of the test shall be repeated and also the tests whic
38、h follow shall be carried out in the required sequence on another full set of samples, all of which shall comply with the requirements. NOTE If the additional set of samples is not submitted at the same time, a failure of one sample will entail a rejection. The applicant when submitting the first se
39、t of samples, may also submit the additional set of samples which may used, should one sample fail. The testing station will then, without further request, test the additional set of samples and will not be accepted only if a further failure occurs. 5.7 When toxic or hazardous processes are used, du
40、e regard shall be taken of the safety of the persons within the test area. 5.8 Liquid tight sheathing systems which are used as an integral part of other equipment shall also be tested in accordance with the relevant standard for that equipment. 6 Classification 6.1 According to mechanical propertie
