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

Application: This device is suitable for mechanical strength test to plugs and socket-outlets, surface type mounting boxes, screw glands, gland covers, switch and other electrical accessories for household and similar purposes.

Test sample: plugs and socket-outlets, surface type mounting boxes, screw glands, gland covers, switch and other electrical accessories.

Feature: The mounting bracket can be moved up and down, left and right moving, and the impact angle can be adjusted. The device is a low energy pendulum impact device for 2J and below.

 

Parameters:

1. Pendulum: Length: 1000mm; external diameter: 9mm; steel pipe wall thickness: 0.5mm; material: steel; weight: 100±1g

2. Mounting bracket: weight: 10±1 kg; it is well-set and the Horizontal direction and the vertical direction can be adjusted. The whole bracket can be rotated 90°through the rotation axis.

3. Striking element: 150g, equivalent mass 200g. (200g striking element for option).

4. Impact energy, equivalent mass and drop height table

Energy/J 0.14 0.2 (0.3) 0.35 (0.4) 0.5 0.7 1 2 5 10 20 50

Notes:

  1. See note in IEC 60068-2-75 3.2.2
  2. In this part, the energy (J) is calculated taking the standard acceleration due to the earth’s gravity(g), rounded up to the nearest whole number, that is 10m/s².
 
  1. Operation: manual release the striking element
