37、ntrolled Copy, (c) BSI6831632- 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 flexing at ambient temperature as a minimum. In this case the test shall be carried out at (20 2) C and the 3rd
38、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 installation and application temperature in a
39、ccordance 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 through the axis of the oscillation. The ap
40、paratus 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 equally about the vertical axis. The assembly
41、 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 sinusoidal forms. 10.5.105 After the test, the sample shall show no sign of disintegration, nor shall there be an
42、y 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 applicable, except as follows: 10.7.3 Replacement: For conduit systems where tensile strength is not declared, the te

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 (5060+) s. Then the voltage drop shall be measured between the points shown in figu
45、re 103 and the resistance calculated from the current and this voltage drop. The resistance shall not exceed 0,05 .
