The impact test for audio, video and similar electronic apparatus

According to IEC 60065 clause 12.1.3, the apparatus is held firmly against a rigid support and is subjected to three blows from F22.50 Spring Hammer Impact Testing 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.

But the non-ventilated solid areas of the enclosure that protect HAZARDOUS LIVE parts shall be subjected to a single impact test by allowing a solid, smooth, steel ball of (50 ± 1) mm in diameter and with the mass of approximately 500 g to fall freely from rest through a vertical distance:

1.For top, sides, back, and front of PORTABLE APPARATUS or table-top apparatus, impact energy is: 2J

2.For all exposed surfaces of fixed mounted apparatus, impact energy is: 2J

3.For top, sides, back, and front of floorstanding apparatus, impact energy is: 3.5J

Zhilitong Electromechanical Co., Ltd manufacturers F22.50 Spring Hammer Impact Testing ZLT-CJ1 with 0.5J impact energy and Diameter 50mm Impact Steel Ball ZLT-GQ2.
