Compliance is checked by inspection. 8 Dimensions Replacement: 8.1 Threads sh
30、all comply with IEC 60423. 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 Construction This clause of part 1 is applicable. 10 Mechanical prop
31、erties This clause of part 1 is applicable, except as follows: 10.1 Mechanical strength 10.1.1 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 test This subclaus
32、e of part 1 is not applicable. 10.5 Flexing test 10.5.101 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 b
33、e made on six samples of conduit of an appropriate 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 ins
34、tallation temperature as given in table 2 with a tolerance of 2 C. Page 6BS EN 61386-23:2004+A11:2010EN 61386-23:2004+A11:2010 (E)6831632- CEI : 2002 6 A manufacturer may declare that a flexible conduit is suitable for transport and installation according to table 1 but may only be suitable for flex
35、ing at ambient temperature as a minimum. In this case the test shall 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 mi
36、nimum application temperature which is ambient and the maximum installation 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 midd
37、le of its travel, the axis of the conduit is vertical and passes through 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 b
38、ackwards and forwards through a total angle of (180 5) divided equally about the vertical axis. The assembly shall be subjected to 5 000 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 sinus
39、oidal forms. 10.5.105 After the test, the sample shall show no sign of disintegration, nor shall there be any cracks visible to normal or corrected vision without magnification. 10.6 Collapse test This subclause of part 1 is not applicable. 10.7 Tensile strength This subclause of part 1 is applicabl

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
42、through the assembly for (5060+) s. Then the voltage drop shall be measured between the points shown in figure 103 and the resistance calculated from the current and this voltage drop. The resistance shall not exceed 0,05 . Page 7BS EN 61386-23:2004+A11:2010EN 61386-23:2004+A11:2010 (E)6831632- CEI
