The Spring Impact Hammer’s Energy required by IEC 60065 Standard


The Spring Impact Hammer’s Energy required by IEC 60065 Standard

Based on requirements of IEC 60065, audio, video and similar electronic apparatus shall have adequate mechanical strength and be so constructed as to withstand such handling as may be expected during intended use.

The apparatus is held firmly against a rigid support and is subjected to three blows from a spring operated impact hammer according to IEC 60068-2-75, applied with a kinetic energy just before impact of 0,5 J to every point of the enclosure that protects HAZARDOUS LIVE parts and is likely to be weak, including ventilation areas, drawers in the pulled-out position, handles, levers, switch knobs and the like, by pressing the release cone perpendicularly to the surface.

This F22.50 Spring Hammer Impact Testing is also made on windows, lenses, signal lamps and their covers, etc.,but only if they protrude from the enclosure by more than 5 mm or if the area of the plane projection of the individual surface area exceeds 1 cm².

Zhilitong Electromechanical Co., Ltd manufactures F22.50 Spring Hammer Impact Testing with 0.5J which conform to IEC 60068-2-75.
