36、.4, 10.2.5, 10.2.6, 10.2.7 and 10.2.8, by the following: 10.2.101 The intermediate steel piece shall be subjected to a uniformly increasing compression force (N) reaching the force indicated in table 4 after (30 3) s. The sample shall flatten by between 25 % and 50 % of its initial outside diameter.

37、 If the sample flattens by less than 25 %, an additional test is carried out whereby the intermediate steel piece is lowered onto the sample at constant speed until the sample is flattened by (30 3) % after (30 3) s and the resultant force is measured. A new sample is subjected to the uniformly incr

38、easing force (N) reaching the force measured above after (30 3) s. The sample shall flatten by between 25 % and 50 % of its initial outside diameter. The force and the intermediate steel piece shall then be removed. Fifteen minutes after removal, the outside diameter of the sample, where it has flat

39、tened, shall be measured again. Page 7BS EN 61386-22:2004+A11:2010EN 61386-22:2004+A11:2010 (E)After the test, the difference between the initial outside diameter and the outside diameter of the flattened sample shall not exceed 10 % of the outside diameter, as measured before the test, and the samp

40、le shall show no cracks visible to normal or corrected vision without magnification. 10.4 Bending test Replacement: 10.4.101 Conduits shall be subjected to a bending test by means of the apparatus as shown in figure 101. 10.4.102 The test shall be made on six samples of conduit, the length of each s

41、ample being at least: a) 30 times the nominal outside diameter for plain conduits; b) 12 times the nominal outside diameter for corrugated conduits. Three of the samples shall be tested at ambient temperature; the other three shall be tested at the minimum declared transport, application and install

42、ation temperature according to table 1, with a tolerance of 2 C. 10.4.103 For the test at ambient temperature, the sample shall be clamped vertically in the bending apparatus as shown in figure 101. The sample shall be slowly bent by hand to the left through an angle of (90 5), back to the vertical

43、position, to the right through an angle of (90 5), and back to the vertical position. This sequence of operations shall be repeated three more times but at the end the sample shall not be bent back to the vertical position. The sample shall be maintained in the bent position for 5 min, after which i

44、t shall be placed in such a position that the straight portions are at an angle of (45 + 5) to the vertical, one end of the sample pointing upwards and the other downwards. For the test at the minimum declared transport, application and installation temperature according to table 1, the sample clamp

45、ed in the bending apparatus as shown in figure 101 shall be conditioned for 2 h in a cold chamber at this temperature with a tolerance of 2 C. After the test, the sample shall show no cracks visible to normal or corrected vision without magnification and it shall be possible to pass the appropriate

46、gauge, as shown in figure 102, through the sample under its own weight and without any initial speed. 10.5 Flexing test This subclause of part 1 is not applicable. 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 f

48、 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 50min1+s. Then the voltage drop shall be measured between the poi

49、nts as shown in figure 103 and the resistance calculated from the current and this voltage drop. The resistance shall not exceed 0,05 . Where special devices are required for the coupling of conduit and terminating conduit fittings, they shall be sufficient to remove the protective coating from the conduit, or the protective finish shall be removed in accordance with the manufacturers instructions. 12 Thermal properties This clause of part 1 is applicable, except as follows: 12.3 Replacement: Th
