24、 (c) BSICONDUIT SYSTEMS FOR CABLE MANAGEMENT Part 23: Particular requirements Flexible conduit systems1 ScopeThis clause of part 1 is applicable, except as follows:Addition:This part of IEC 61386 specifies the requirements for flexible conduit systems.2 Normative referencesThis clause of part 1 is a
25、pplicable.3 DefinitionsThis clause of part 1 is applicable.4 General requirementsThis clause of part 1 is applicable.5 General conditions for testsThis clause of part 1 is applicable.6 ClassificationThis clause of part 1 is applicable, except as follows:Subclauses 6.1.3 1, 6.1.3 2 and 6.1.3 3 are no
26、t applicable.NOTE Flexible conduit systems according to 6.1.1 1, 6.1.1 2, 6.1.2 1, 6.1.2 2 and classification 1X from 6.2.1, table 1 are not allowed in France.7 Marking and documentationThis clause of part 1 is applicable, except as follows:Addition:7.1.101 The conduit shall be marked in accordance
27、with 7.1 along its entire length at regular intervals 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, or on the packaging.Licensed Copy: :FULLNAME, : DATE, Uncontrolled Copy, (c) BSICompliance is chec
28、ked by inspection.7.1.102 The manufacturer shall document or add to the packaging for the system the minimum inside diameter, the minimum bend radius and the classification in accordance with clause 6.Compliance is checked by inspection.8 DimensionsReplacement:8.1 Threads shall comply with IEC 60423
29、.Compliance is checked by means of the gauges specified in IEC 60423.8.2 The minimum inside diameter of the conduit system shall be as declared by the manufacturer.Compliance is checked by measurement.9 ConstructionThis clause of part 1 is applicable.10 Mechanical propertiesThis clause of part 1 is
30、applicable, except as follows:10.1 Mechanical strength10.1.1 Addition:NOTE Very light flexible conduits should not be considered as providing adequate mechanical protection and should not be used within the construction of buildings.10.4 Bending testThis subclause of part 1 is not applicable.10.5 Fl
31、exing test10.5.101 An assembly consisting of a conduit with a terminating conduit fitting, assembled in accordance with the manufacturers instructions, shall be subjected to a flexing test by means of the apparatus shown in figure 101.10.5.102 The test shall be made on six samples of conduit of an a
32、ppropriate length. Three of the samples shall be tested at the minimum declared transport, application and installation temperature as given in table 1 with a tolerance of 2 C. The other three samples shall be tested at the maximum declared application and installation temperature as given in table
33、2 with a tolerance of 2 C.Licensed Copy: :FULLNAME, : DATE, Uncontrolled Copy, (c) BSIA manufacturer may declare that a flexible conduit is suitable for transport and installation according to table 1 but may only be suitable for flexing at ambient temperature as a minimum. In this case the test sha
34、ll be carried out at (20 2) C and the 3rd digit of the classification code shall be X. The manufacturer shall clearly declare in his literature both the minimum transport and installation temperature in accordance with table 1, the minimum application temperature which is ambient and the maximum ins
35、tallation and application temperature in accordance with table 2.10.5.103 The sample shall be fixed to the oscillating member by means of the terminating conduit fitting as shown in figure 101, so that when the conduit is at the middle of its travel, the axis of the conduit is vertical and passes th
36、rough the axis of the oscillation. The apparatus with the sample shall be conditioned for 2 h or until the sample has attained the declared temperature, whichever period is the longer.10.5.104 The oscillating member shall be moved backwards and forwards through a total angle of (180 5) divided equal
37、ly about the vertical axis. The assembly shall be subjected to5 000 flexings at a rate of (40 5) flexings per minute. A flexing constitutes, starting from the vertical position, one continuous cycle of movement of essentially sinusoidal forms.10.5.105 After the test, the sample shall show no sign of
38、 disintegration, nor shall there be any cracks visible to normal or corrected vision without magnification.10.6 Collapse testThis subclause of part 1 is not applicable.10.7 Tensile strengthThis subclause of part 1 is applicable, except as follows:10.7.3 Replacement:For conduit systems where tensile
39、strength is not declared, the tensile strength of the joint shall comply with classification 1 in table 6.11 Electrical propertiesThis clause of part 1 is applicable, except as follows:11.2 Bonding testReplacement:0A sample of a conduit and terminating conduit fitting shall be assembled in accordance with the manufacturers instructions and mounted as shown in figure 103. A current of 25 A, having a frequency of 50 Hz to 60 Hz, derived from an a.c. source having a no-load voltage not exceeding 12 V, shall be passed through the assembly for ( 60 +5 ) s.
