2J Below Pendulum Hammer Test Apparatus for Testing Socket-Outlet and Switches

1. Introduction

the IK01 to IK06 pendulum hammer test apparatus is for the test of energies not exceeding 1J, it is consisted by test apparatus, striking element, mounting fixture, sheet of plywood and steel tube. The test apparatus can meet the requirement of IEC60068-2-78 annex D and IEC60884-1 clause 24.1 and figure 22 to 26, it is applied to the mechanical strength test for household and similar use plugs, sockets and surface-type mounting box, screw glands, covers, switches and other electrical accessories.

The striking element made of polyamide (radius of 10mm, mass of 150g and rockwell hardness of HT100) is firmly fixed to the lower end of the steel tube with an outer diameter of 9mm and a wall thickness of 0.5mm, the pendulum pivot is in the upper end of steel tube, to make the steel tube can only move in the vertical plane through the axis of the pendulum pivot. The axis of the pendulum pivot should be 1000mm above the axis of the striking element. The specimens are mounted on a sheet of plywood 8mm thick and 175mm square, the top and bottom edges of the plywood should be firmly fixed on a rigid bracket, which is part of mounting fixture. The specimen (like surface-type socket-outlets and surface-type mounting box) are mounted on the plywood as in normal service. The specimen (like flush-type socket-outlet) is not possible to mount on the plywood directly, a suitable adapter would need to be prescribed.
