IEC 60068-2-75 Test EHA Pendulum Hammer Test Apparatus With 10kg Mounting Support

IEC 60068-2-75 Test EHA Pendulum Hammer Test Apparatus With 10kg Mounting Support

IEC60884-1 Clause 24.1

The specimens are checked by applying blows by means of the pendulum hammer test apparatus as described in IEC 60068-2-75 (test EHA), with an equivalent mass of 250 g.
The specimens are mounted on a sheet of plywood, 8 mm nominal thickness and approximately 175 mm square, secured at its top and bottom edges to a rigid bracket which is part of the mounting support.
The mounting support shall have a mass of (10 ± 1) kg and shall be mounted on a rigid frame by means of pivots. The frame is fixed to a solid wall.
The design of the mounting is such that
– the specimen can be placed in such a way that the point of impact lies in the vertical plane through the axis of the pivot,
– the specimen can be moved horizontally and turned about an axis perpendicular to the surface of the plywood,
– the plywood can be turned 60°, in both directions about a vertical axis.
Surface type socket-outlets and surface-mounting boxes are mounted on the plywood as in normal use.
Inlet openings which are not provided with knock-outs, are left open; if they are provided with knock-outs, one of them is opened.
Flush-type socket-outlets are mounted in a recess provided in a block of hornbeam or material having similar mechanical characteristics, which is fixed to a sheet of plywood, and not in its relevant mounting box.
If wood is used for the block, the direction of the wood fibres shall be perpendicular to the direction of impact.
Flush-type screw fixing socket-outlets shall be fixed by means of screws to lugs recessed in the hornbeam block. Flush-type claw fixing socket-outlets shall be fixed to the block by means of the claws.
Before applying the blows, fixing screws of main parts and covers are tightened with a torque equal to two-thirds of that specified in table 6.
The specimens are mounted so that the point of impact lies in a vertical plane through the axis of the pivot.
The striking element is allowed to fall from a height specified in table 21.

Standard: IEC60884-1 2013 clause 24.1 and figure 22~26, IEC60669-1, IEC60068-2-75
