Product Description：
Name：IEC 60068-2-75 IK Vertical Drop Hammer Impact Test Apparatus
Type：BND-LCC
Appliance:
Vertical drop hammer test device is designed and manufactured according to IEC60068-2-75 standard, it is used to carry on the anti-impact ability test to the electrical home appliances and accessories or electronic electrical products or accessories.
The hammer consists of a basic striking element, the drop height being selected from the standard table 2 and falling vertically from the quiescent state to the horizontal surface of the sample. The characteristics of the impact elements shall be as specified in Table 1 of the Standards. The impact member may be guided by a negligible constraint. The guide tube should not come into contact with the sample and keep the hammer free to fall. In order to reduce friction, the length of the impact element should not be less than the diameter, with the pipe to maintain a proper gap.

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.
