21、 prepared by CENELEC Technical Committee TC 113, Cable management systems. The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50086-2-2 on 1994-12-06. This Part 2-2 specifies particular requirements for pliable conduit systems. A conduit system which complies wi

22、th this standard is deemed safe for use. The following dates were fixed: For products which have complied with the relevant national standard before 1996-12-01, as shown by the manufacturer or by a certification body, this previous standard may continue to apply for production until 2001-12-01. This

23、 Part 2-2 supplements or modifies the corresponding clauses of EN 50086-1:1993, Conduit systems for cable management Part 1: General requirements. Where a particular clause or subclause of Part 1 is not mentioned in this Part 2-2, that clause or subclause applies as far as is reasonable. Where this

24、Part 2-2 states “addition”, “modification” or “replacement”, the relevant text of Part 1 is to be adapted accordingly. Subclauses, tables and figures which are in addition to those in Part 1 are numbered starting with 101. Annexes which are in addition to those in Part 1 are labelled AA, BB, etc. Fo

25、reword to amendment A11 At the request of the Finnish electrotechnical committee, a draft for an amendment to EN 50086-2-2:1995 was submitted to the CENELEC members for acceptance in October 1998.

31、 February 2002 3 1 Scope This clause of Part 1 is applicable, except as follows. Addition: This standard specifies the requirements for pliable conduit systems including self-recovering conduit systems. Conduit systems which are used as an integral part of other equipment also have to be tested acco

33、cation This clause of Part 1 is applicable, except as follows. 6.1.1.1, 6.1.2.1, 6.1.3.1, 6.1.3.4, 6.1.4.1 and 6.1.5.1 are not applicable. 7 Marking and documentation This clause of Part 1 is applicable, except as follows. Addition: 7.1.101 The conduit shall be marked in accordance with 7.1 at regul

34、ar intervals along its length of preferably 1 m but not longer than 3 m. Where this is technically impractical, the mark shall be on a label attached to the product at each end. Compliance is checked by inspection. 7.1.102 The manufacturer shall document for the system the minimum inside diameter an

35、d the classification in accordance with clause 6. Compliance is checked by inspection. 8 Dimensions Replacement: 8.1 Threads shall comply with EN 60423. Outside diameters of non-metallic conduits shall comply with EN 60423. Outside diameters of metallic and composite conduits need not comply with EN

36、 60423, providing they are used with terminating fittings with threads complying with EN 60423. Compliance is checked by means of the gauges specified in EN 60423. 8.2 Threadable conduits and threadable conduit fittings shall comply with Table 101. Non-threadable conduit fittings shall comply with T

37、able 102. The minimum inside diameter of the conduit system shall be declared by the manufacturer. Compliance is checked by measurement.

40、ot exceeding 50 % of its initial outside diameter within 30 s. The compression force shall not be less than the values given in Table 4. The force and the intermediate piece shall then be removed. Fifteen minutes after removal, the outside diameter of the sample, where it has flattened, shall be mea

41、sured again. After the test, the difference between the initial outside diameter and the outside diameter of the flattened sample shall not exceed 10 % of the outside diameter, as measured before the test and the sample shall show no cracks visible to normal or corrected vision without magnification

45、es the nominal outside diameter for plain conduits; b) 12 times the nominal outside diameter for corrugated conduits. Three of the samples shall be tested at the ambient temperature; the other three shall be tested at the declared transport, permanent application and installation temperature in acco

46、rdance with Table 1 with a tolerance of 2 C. 10.4.103 For the test at ambient temperature, the sample shall be clamped vertically in the bending apparatus in accordance with Figure 101. The sample shall be slowly bent by hand to the left through approximately 90 , back to the vertical position, to t

47、he right through approximately 90 , and back to the vertical position. This sequence of operations shall be repeated three more times but at the end the sample shall not be bent back to the vertical position. The sample shall be maintained in the bent position for 5 min, after which it shall be plac

48、ed in such a position that the straight portions are at 45 to the vertical, one end of the sample pointing upwards and the other downwards. For the test at the declared transport, permanent application and installation temperature, the sample clamped in the bending apparatus as shown in Figure 101 s

49、hall be conditioned for 2 h in a cold chamber at this temperature 2 C. After the test, the sample shall show no cracks visible to normal or corrected vision without magnification and it shall be possible to pass the appropriate gauge, in accordance with Figure 102, through the sample under its own weight and without any initial speed. 10.5 Flexing test This subclause of Part 1 is not app
