Impact Testing Machine Low Energy Pendulum Hammer Test Apparatus 9mm Steel Tube Manual Release 1000mm Pendulum

 

Standard:

IEC60068-2-75 Environmental testing –Part 2: Tests – Test Eh: Hammer tests clause 5 Test Eha: Pendulum hammer; IEC 60884-1 'Plugs and socket-outlets for household and similar purposes – Part 1: General requirements' clause 24.1, figure 22-26

 

Standard description:

The test apparatus consists basically of a pendulum rotating at its upper end in such a way as to be kept in a vertical plane. The axis of the pivot is at 1 000 mm above the measuring point. The pendulum is composed of a nominally rigid arm and of a striking element complying with the requirements of table 1 .

For testing heavy, voluminous or difficult to handle specimens, a portable pendulum may be used. It shall comply with the above description but its pivot may be fixed directly on the specimen or on a movable structure. In this case, it shall be ensured that, before the tests, the axis of the pendulum is horizontal, that its fixing is sufficiently rigid, and that the impact point is in the vertical plane passing through the axis.

In all cases, when the pendulum is released, it shall be allowed to fall only under the influence of gravitational force.

 

Test apparatus for severities not exceeding 1 J

The striking element comprises a steel body with a polyamide insert having a hemispherical face. Its combined mass is 200 g (1 50 g) ± 1 g so that the equivalent mass complies with Table 1 . Annex D gives an example of a test apparatus.

 

Figure D.1 shows an example of a pendulum hammer test apparatus for energies not exceeding 1 J. The striking element complies with 5.2.2 and Figure D.2. The arm is a steel tube with an external diameter of 9 mm (nominal), and a wall thickness of 0,5 mm (nominal).

The specimens are mounted on a sheet of plywood 8 mm thick and 1 75 mm square, preferably according to ISO 1 098, secured at its top and bottom edges to a rigid bracket, which is part of the mounting fixture, as shown as an example in Figure D.3. The mounting fixture has a mass of 1 0 kg ± 1 kg and is mounted on a rigid frame by means of pivots. The frame is itself fixed to a solid wall.

The design of the mounting is such that

a) the specimen can be placed so that the point of impact lies in the vertical plane through the axis of the pendulum pivot,

b) the specimen can be moved horizontally and turned about an axis perpendicular to the surface of the plywood,

c) the plywood can be turned about a vertical axis.

The specimens are mounted on the plywood as in normal service. Where it is not possible to mount the specimen directly on the plywood, a suitable adapter should be prescribed by the relevant specification. An example of an adapter for flush-type switches is shown in Figure D.4, and an example of an adapter for lamp holders is shown in Figure D.5.

 

 

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).

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.
