In addition, for conduit systems according to 6.1.1.1 the manufacture

39、r shall give instruction for installation precautions following the relevant national technical rules, if any. 8 Dimensions Replacement: Conduit dimensions should preferably be according to Table 101. Compliance of the minimum inside diameter is checked by measurement according to two perpendicular

40、diameters on the same section and calculating the average value. Compliance of the outside diameter is checked using a ring gauge or any suitable method. 9 Construction This clause of Part 1 is applicable except as follows: 9.3 and 9.4 Not applicable. 10 Mechanical properties This clause of Part 1 i

41、s applicable except as follows: 10.1.4 Replacement:Compliance is checked by the tests of 10.2 to 10.4 10.2 Compression test Replacement: 10.2.1 Conduits are subjected to a compression test. NOTE Compression test on fittings is under consideration The test for conduits containing non-metallic materia

42、ls is not started until 10 days after manufacture. 10.2.2 Samples are (200 5) mm long.BS EN 61386-24:201061386-24 IEC:2004 15 10.2.3 Before the test, the outside and inside diameters of the samples are measured as specified in Clause 8.10.2.4 The samples are compressed between two flat steel plates

43、having minimum dimensions (100 x 220 x 15) mm, the length 220 mm being along the length of the sample. The samples are compressed at a rate of (15 0,5) mm/min and the load recorded at the vertical deflection equivalent to 5% of the average value of the original inside diameter of the sample. 10.2.5

44、When reaching the deflection of 5 %, the applied force shall be at least: 250 N for conduits according to 6.1.1.1 ; 450 N for conduits according to 6.1.1.2; 750 N for conduits according to 6.1.1.3. NOTE The deflection is calculated with the inner diameter but the measurement of the outside diameter

45、may be sufficient. In case of doubt, it will be necessary to measure the inner diameter. 10.2.6 After the test, there shall be no crack allowing the ingress of light or water between the inside and the outside. 10.3 Impact test Replacement:10.3.1 Twelve samples of conduits each (200 5) mm in length

46、or conduit fittings are subjected to an impact test by means of the apparatus shown in Figure 101. Conduits are tested alone. Fittings are tested when assembled with conduits. NOTE 1 If necessary, for the test purposes conduit fittings may be trimmed as long as the test result is not affected. NOTE

47、2 For determination of mass of hammer, the hammer is to be considered as the head of hammer plus the guidance carriage. 10.3.2 The test apparatus is placed on a firm flat surface. The samples are conditioned in a cold chamber at the temperature of (5 1)C for 2 h. The samples are removed from the col

48、d chamber and placed on the vee-block as shown in Figure 101. The hammer falls once on each sample. The time between removal of the sample from the cold chamber and completion of impact does not exceed 10 s. The energy values are specified in Table 102. The test is made on the weakest part of the co

49、nduit fitting except that it is not applied within 5 mm of any sample entry. Samples of conduit are tested on the centre of their length. BS EN 61386-24:201061386-24 IEC:2004 17 10.3.3 After the test, when the samples have attained (20 5) oC, it shall be possible to pass the appropriate ball specified in 10.4.3 through the conduit, under its own weight and without any initial speed, with the sample in the vertical position. There shall be no sign of disinteg
