Figure E.1 shows an example of a spring hammer test apparatus complying with clause 5, for energies not exceeding 1 J. The mass of the body assembly is 1250 g ± 10 g. The hammer head is fixed to the hammer shaft in such a way that the distance from its tip to the plane of impact (the plane of the cone truncation), when the striking element is on the point of release,has approximately the value shown for the spring compression in table E.1.

IK01-06 Spring Impact Hammer is used to simulate the mechanical impact that the tested product may encounter in normal use, so as to check the ability of the tested product shell to withstand mechanical impact. It is suitable for mechanical strength test of enclosures, operating levers, handles, knobs, indicator lights, signal lights and lamp shades of accessories such as household and similar lighting fixtures, household appliances, and electronic products to ensure that the tested products can withstand possible reckless operations. and other accidents, so that the tested product can operate normally and safely and reliably.

Degrees of protection against external mechanical impacts:
