10.5Flexing test
10 5.101 An assemhly of conduit with a terminating fitting, assemhled in accordance with the
manufacturer's instructions, shall be subjected to a flexing test by means of the apparatus shown in Figure 10I
10.5.102 The test shall be made on six samples of conduit of an appropriate length Three of the samples shall be tested at the declared transport, permanent application and installation temperature in
accordance with Table 1 with a tolerance of±2DC.The other three sarnples shall be tested at the declared permanent application and installation temperature in accordance with Table 2 with a tolerance of ±2°C
10.5.103The smnple shall be fixed to the oscillating member by means of the terminating fitting as shown
in Figure 101, sothat 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 apparatus with the sample shall be conditioned for2 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° divided equally about the vertical axis The assembly shall be subjected to 5 000 flexings at a rate of
40±5 fiexings per minute A flexing constitutes starting from the vertical position, one continuous cycle of lll0venlent of essentially sinusoidalfOlln.

Rcplaccment:
A sample of conduit and terminating fitting shall be assembled in accordance with the manufacturer's Instructions and Figure 103 A current of25 A, having a ftequency of 50 Hz to 60 Hz, derived fronl an a.c source having a no-load voltage not exceeding 12 V, sha!! be passed through the assembly
for I min I~S,after which the voltage drop shall be measured between the points shown in Figure 103 and the resistal1ce calculated from the current and this voltage drop
The resistance shall not exceed 0,05 Q.
Where special devices are required for the coupling ofconduit and terminating fitting, it shall be sufficient
to remove the protective coating from the conduit, or the protective finish shall be removed in accordance with the manufacturer's instructions before the voltage is applied
