34、 subclauses 14.3.1, 14.3.2 and 14.3.3. Additional subclauses: 14.3.101 External load test PT systems shall withstand mechanical stresses applied to the PT system. BS EN 61534-21:2014 8 IEC 61534-21:2014 IEC 2014 Compliance is checked by the following test. At least two lengths of the PT system are j
35、oined together including the electrical connection and installed according to the manufacturers instructions to a rigid support; the joint shall be placed midway between the fixing devices. A steel plate with a length of (150 20) mm, a width not less than the PT system and a thickness of (5 1) mm is
36、 positioned on the upper surface of the PT system centrally at the midpoint between the supports. For classifications 7.101.1.1 and 7.101.2.1, a vertical force is gradually applied on the steel plate up to (350 10) N over a period of (60 1) s and maintained for (60 1) min. For classifications accord
37、ing to 7.101.1.2 and 7.101.2.2, a vertical force is gradually applied on the steel plate up to (750 10) N or with a force declared by the manufacturer 2 %, whichever is the higher over a period of (60 1) s and maintained for (60 1) min. During the tests, the sample shall not break and shall neither
38、have parts that have worked loose, nor shall it show any deformation likely to impair electrical safety. After the test: The sample shall comply with Clause 10 and 11.1 of IEC 61534-1:2011 and IEC 61534-1:2011/AMD1:2014. There shall be no permanent deformation, which would prevent the correct insert
39、ion and withdrawal of the tap-off units. The samples shall withstand the test according to 15.2 but without the pre-conditioning of 15.1, and the tests of 11.3 of IEC 61534-1:2011 and IEC 61534-1:2011/AMD1:2014. 14.3.102 PT systems with provision for suspended loads PT systems classified according t
40、o 7.102.2 shall withstand mechanical loads applied to the suspension means in normal use. Compliance is checked by the following test. The provision for the suspension means is installed as for normal use according to the manufacturers instructions. Screwed connections, if any, intended to provide m
41、echanical support of the suspension means are tightened to the torque given in the relevant column of Table 5 of IEC 61534-1:2011 if not specified by the manufacturer. The suspension means is then loaded, without jerks, with a force declared by the manufacturer 2 % or if no force is declared then th
42、e test shall be performed with a force of (250 5) N , for (24 1) h. During the test, the PT system and the suspension means shall not become detached from one another and shall show no damage, which leads to non-compliance with this standard. 14.3.103 PT systems with tap-off units In normal use, the
43、 construction of the tap-off unit shall be such as to prevent disconnection from the PT or live parts becoming accessible. Compliance is checked by the following test. The tap-off unit is inserted as in normal use 10 times and withdrawn 10 times in the tap-off outlet with the PT system installed in
44、normal use as declared by the manufacturer. BS EN 61534-21:2014IEC 61534-21:2014 IEC 2014 9 The tap-off unit is inserted once more into the tap-off outlet as in normal use and a withdrawal force of (30 1) N is applied for (60 5) s parallel to the force on the tap-off unit in normal use as declared b
45、y the manufacturer. The tap-off unit shall not become disconnected from the PT and live parts shall not become accessible when tested according to 11.1.1.1 of IEC 61534-1:2011 and IEC 61534-1:2011/AMD1:2014. 15 Insulation resistance test and dielectric strength test Clause 15 of IEC 61534-1:2011 is

Additional subclause: 21.2.101 Protection against ingress of water for wet treatment of the floor Where PT sys
48、tems are fitted at the skirting position and the floor is subject to wet treatment then the PT system shall have a minimum degree of protection of IP X4. 22 Electromagnetic compatibility Clause 22 of IEC 61534-1:2011 is applicable.
