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 with a tolerance of±2 DC The other three sarnples shall be tested at the declared permanent application and installation temperature in accordance with Table with a tolerance of ±2°C 10.5.103 The smnple shall be fixed to the oscillating member by means ofthe 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 for 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 000 flexings at a rate of 40 ± fiexings per minute A flexing constitutes starting from the vertical position, one continuous cycle of lll0venlent of essentially sinusoidal fOlln 10.5.105 After the test, the sample shaH show no sign

sub-clause of Part is applicable, except as foiiows 10.7.3 Replacement: For conduit systems where tensile strength is not declared, the tensile strength of the joint shall comply with classification I in Table 11 Electrical properties This clause of Part I is applicable, except as follows 1.5 Bonding lcsl 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 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 :CBSI 26 February 2002 EN 50086-2-3:1995 12 Thermal properties This clause of Part I
