    what is EN/IEC 60068-2-75 IK hammer test and striking elements?
    From: BONAD  Date: 2024-03-15 15:01:07


    WHAT IS STANDARD EN/IEC 60068-2-75?

    HAMMER TEST

    Standard EN/IEC 60068 consists of 3 methods for testing the impact resistance of a test object against impacts with different severity levels. It serves to demonstrate the mechanical strength of a product and is intended primarily for the testing of electrical equipment. The test consists of a standardised test procedure with a defined number of impacts on the test object with a defined impact energy. Standard IEC 60068-2-75 covers impact energies from 0.14 J to 50 J.
