28、f IEC 61386 specifies requirements and tests for conduit systems, including conduits and conduit fittings, 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 m
29、etallic, non-metallic and composite conduit systems, including threaded and non-threaded entries which terminate the system. This standard does not apply to enclosures and connecting boxes which come within the scope of IEC 60670. NOTE 1 Certain conduit systems may also be suitable for use in hazard
30、ous atmospheres. Regard should then be taken of the extra requirements necessary for equipment to be installed in such conditions. NOTE 2 Earthing conductors may or may not be insulated. 2 Normative references The following referenced documents are indispensable for the application of this document.

39、 and helical corrugated conduits are permissible, and a combination of both corrugated and plain conduit is possible. 3.11 rigid conduit conduit which cannot be bent, or which can only be bent with the help of a mechanical aid, with or without special treatment 3.12 pliable conduit conduit which can
40、 be bent by hand with reasonable force, and which is not intended for frequent flexing 3.13 flexible conduit conduit which can be bent by hand with reasonable small force, and which is intended to flex frequently throughout its life BS EN 61386-1:2008 6 3.14 self-recovering conduit pliable conduit w

43、ng materials, low and high temperatures, and corrosive or polluting substances. 4 General requirements 4.1 Conduit and conduit fittings shall be so designed and constructed that in normal use their performance is reliable and they provide protection to the user or surroundings. When assembled in acc
44、ordance with manufacturers instructions as part of a conduit system, conduits and conduit fittings shall provide mechanical and, where required, electrical protection of the insulated conductors and cables contained therein. 4.2 The protective properties of the joint between the conduit and conduit
45、fitting shall not be less than that declared for the conduit system. 4.3 Conduit and conduit fittings shall withstand the stresses likely to occur during transport, storage, recommended installation practice and application. 4.4 Compliance is checked by carrying out all specified tests. 5 General co
46、nditions for tests 5.1 Tests in accordance with this standard are type tests. Conduit systems, having the same classification, which can vary in colour only, shall be the same product type. 5.2 Unless otherwise specified, the tests shall be carried out at an ambient temperature of (20 5) C. 5.3 Unle
47、ss otherwise specified, each test shall be made on three new samples, which may be taken from one length. 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 furt
48、her tests. BS EN 61386-1:2008 7 5.4 Samples of non-metallic and composite conduits and conduit fittings shall be conditioned for at least 240 h, at a temperature of (23 2) C and a relative humidity between 40 % and 60 %. All tests shall be carried out immediately after general conditioning. 5.5 Unle
49、ss otherwise specified, the samples for each test shall be in a clean and new condition, with all parts in place and mounted as in normal use. After checking dimensions in accordance with Clause 8, and unless otherwise specified in the relevant test, the conduit fittings shall be assembled with adequate lengths of conduit of the type for which they are intended. Due regard shall be taken of the manufacturers instructions, especially where force is required in the assembly of
