Difference of Spring hammer, pendulum impact hammer device and vertical hammer

The differenct of the Spring hammer, pendulum impact hammer test device and Veritcal hammer impact test apparatus

The three test apparatus are intended to given similar results as far as is practicable. To obtain repeatable and reproducible results, this test is more dependent on the details of the test apparatus than is usual in IEC60068 standards.

The choice of the test apparatus depends on the orientation of the surface to be tested and on the energy level. Not all methods can be used in every case. When the specimen cannot be moved or turned, for any reason, the choice is limited.

-The Pendulum Hammer can only be sued on vertical surface without overhangings. We have two model pendulum hammer test device, CX-BC20http://www.hkcx17.com/product/showproduct.php?lang=en&id=260 used for the impact energy above 2J and CX-IM05http://www.hkcx17.com/product/showproduct.php?lang=en&id=302 used for the impact energy below 2J test.

-The vertical hammer can normally only be used on accessible horizontal surfaces.   

-The spring hammer can be used in any position, provided there is enough room to apply it correctly, and that the specified impact energy does not exceed 2J. For higher energy levels, a spring hammer would be too difficult to handle, and could even be hazardous for the operator. 

We have produced two types spring hammer for selection, single impact spring hammer energy from IK01 to IK07 http://www.hkcx17.com/product/showproduct.php?lang=en&id=87 and universal spring impact hammer which energy can be adjusted from IK01 to IK06 http://www.hkcx17.com/product/showproduct.php?lang=en&id=88
