IK07-IK11 Pendulum Impact Hammer Testing Equipment
1. Introduction
IK07 to IK10 pendulum impact hammer testing equipment can meet the test requirements of IEC60068-2-75 and IEC62262 for severities of 2J and above. The pendulum hammer can be used on vertical surfaces without overhangings. And the test is applied to EV charger, luminaire, electrical appliances and etc. for verifying the mechanical strength.
The equipment is mainly consisted by test rig, pendulum rod and striking elements. The working principle is to place the sample in normal, and adjust the impact points; position the impact hammer, and then release the hammer from a certain height (falling height) to freely impact the specimen, the impact generator will be generated. The impact angle and impact height can be adjusted to fit with the impact points.
