Before the test non metallic and composite slotted trunking lengths
42、 are aged at a temperature declared according to Table 3 for (168 4) h continuously. The sample is securely fixed, using 10 mm external diameter flat metallic washers and appropriate metallic screws to a rigid smooth support such as a plywood board 16 mm thick. When 10 mm external diameter is too la
43、rge, suitable smaller washer and appropriate screw are used. Fixing(s) are positioned as shown in Figure 103 at (200 5) mm centres along the length of the sample. Within the width of the sample: for trunking with a width less than 50 mm, one fixing is used as shown in Figure 103 a); for trunking wit
44、h a width equal or greater than 50 mm, two fixings are used as shown in Figure 103 b). If the manufacturers instructions require the use of cable retainers or dividers, these are fitted according to the manufacturers instructions. Cable retainers, if any, are symmetrically fixed along the length. Th
45、e sample is subjected to an evenly distributed load of 0,8 g per mm of the declared usable area for cables, per metre length. The load is distributed between the compartments proportionally to the declared usable area. The load consists of copper insulated conductors or cables complying with class 5
46、, Table 3 of HD 383 S2:1986, or flexible insulated conductors or cables of similar mass per meter. BS EN 50085-2-3:2010EN 50085-2-3:2010 8 To allow for settlement of the sample, a pre-load of 10 % of the load is applied and removed after (300 30) s. The measurement apparatus is then calibrated to ze
47、ro. Insulated conductors or cables of 25 mm nominal cross section are placed in the sample so that approximately 50 % of the load is achieved. Insulated conductors or cables of 2,5 mm nominal cross section are placed on top of the larger cables to achieve the total load within a tolerance of 5 g. If
48、 the dimensions of the compartment do not permit the accommodation of 25 mm insulated conductor or cable, 2,5 mm nominal cross section insulated conductors or cables are used. Non metallic and composite slotted trunking lengths are tested at the maximum application temperature declared by the manufa
49、cturer according to Table 3. 10.2.2 Slotted trunking lengths are mounted according to Figure 104 a). After (120 + 5/0) min with the load still applied the vertical deflection F is measured at approximately the middle of the length. F shall not exceed 10 % of the height H with a maximum of 10 mm (see Figure 104 a). 10.2.3 Slotted trunking lengths classified according to 6.101.1 are mounted according to Figure 104 b). After (120 + 5/0) min with the load still applied
