Asker® Instruments
The Asker® Durometer Type JA is a Japanese Industrial Standard and becoming less widely used since the ASTM D2240 Type A was standardized in the ISO. It is suited for the hardness measurement of a wide range of materials, from harder elastomers to softer plastics. Please note that although the spring force of a “JA” is slightly more than that of a D2240 Type A, most test results are very similar.

Asker® Instruments
The Asker® Durometer Type JC is a Japanese Industrial Standard. It is suited for measurement of material whose hardness is above that of 70 JA. Incorporating an "JA" style indentor and a 4500 gf spring, it is suited for the hardness measurement of a wide range of materials, from rigid elastomers to harder plastics. Please note that although the spring force of a “JC” is slightly less than that of a D2240 Type C, most test results are very similar.
