load testpt systems shall withstand mechanical stresses applied to the pt system.compliance is checked by the following test.at least two lengths of the pt system are jointed together including the electrical connection and installed according to the manufacturers instructions on rigid supports; the joint shall be placed midway between the supports.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 positioned on the upper surface of the pt system centrally at the midpoint between the supports. for all classifications excluding and , a load is slowly applied on the steel plate up to (350 10) n within (60 to 120) s and maintained for 1 h. for classifications according to and , a load is slowly applied on the steel plate up to (750 10) n or with a force declared by the manufacturer 2 %, which ever is the higher within (60 to 120) s and maintained for 1 h.during the tests, the sample shall not break and shall neither have parts that have worked loose, nor shall it show any deformation likely to impair electrical safety.licensed copy: sheffieldun sheffieldun, na, fri nov 10 07:38:29 gmt+00:00 2006, uncontrolled copy, (c) bsiafter the test:the sample shall comply with clause 10 and 11.1.there shall be no permanent deformation, which would prevent the correct insertion and withdrawal of the tap-off units.the samples shall withstand the test according to 15.2 but without the pre-conditioning of15.1, and the tests of .102pt systems with provision for suspension of external loadpt systems classified according to , and shall withstand mechanical stresses applied to the suspension means occurring 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 mechanical support of the suspension means are tightened to the torque given in the relevant column of table 5 of part 1 if not specified by the manufacturer.the suspension means is then loaded with a force of (2505) n or with a force declared by the manufacturer 2%, whichever is the higher, for 24 h.note in uk and germany there is no requirement for suspension means to withstand 250n.during the test, the pt system and the suspension means shall not become detached from one another and the specimen shall show no damage, which leads to non-compliance with this standard.14.2.103pt systems with tap-off unitsin normal use, the construction of the tap-off unit shall be such as to prevent disconnection from the powertrack 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 normal use as declared by the manufacturer.the tap-off unit is inserted once more into the tap-off outlet as in normal use and a 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 by the manufacturer.the tap-off unit shall not become disconnected from the powertrack and live parts shall not become accessible when tested according to .en 61534-21:2006 licensed copy: sheffieldun sheffieldun, na, fri nov 10 07:38:29 gmt+00:00 2006, uncontrolled copy, (c) bsi15 insulation resistance test and
