          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.
