Durometers for Hardness Test of Plastic
This standard is prescribed by plastic industry in Japan apart from testing method of hardness of rubber. This is basically equal to Durometer of JIS K 6253, as only its round up method of spring load value etc. is different. But we distinguish model name as another Durometer according to the view of conformity to standard.
Peak Pointer Type
Some of Rubbers, Elastomer’ elastic body is not easily read the maximum value after firm contacting with a presser foot of durometer , due to the stress relaxation. The pointer indicates the descendent value but the peak pointer is holding the maximum measured value. The peak pointer type can easily read the maximum value efficiently.
In case the pointer cannot be read directly due to some obstacles altough the measuring can be done, the mesured value can be confirmed from peak pointer after measuring. The upper / lower limiters equipped will be effectively used in tolerance judgment.
Pressurized Face φ18mm Durometer mounted to Stand
Pressurized face diameter of type A and type D durometer mounted to a stand is defined 18mm by JIS standard and ISO standard. φ18mm type A(GS-719R) and type D (GS-720R) can be used as they are for measuring by pushing by hand.
