The JSA JIS C 60068-2-75 standard specifies the method of hammer test (test Eh) for evaluating the tolerance of electrical and electronic products under mechanical Impact conditions. The standard provides three standardized test methods, including pendulum test (Eha), spring hammer test (Ehb) and vertical hammer test (Ehc), to simulate Impact conditions in different scenarios. The test is designed to verify the structural integrity and functionality of the product in the event of a mechanical collision, ensuring its safety and Reliability in actual use. The standard is suitable for assessing the robustness of the product in standing restricted areas or crash prone environments, especially for the testing of fragile equipment.
