Shore durometer is used to test hardness of sulfureted rubber and plastics, such instrument has A-type/D-type/C-type.

A-type and D-type apply to test the low and medium level hardness and high level hardness of materials.

C-type applies to test the hardness of shoe-making porous materials made by vesicants within plastics when the compression rate is 50% and stress is beyond 0.049MPa.

Operation instructions

Put the sample on a solid plane, hold the durometer to make the indenter at least 12mm away from the sample edge, and stably put the legs of durometer on the sample. Thus the indenter straightly goes into the sample till the legs completely get to the sample. Check the reading in 1s.Repeat such test 5 times at different place which are at least 6mm away from the test point and find the average reading (the distance between porous materials is at least 15mm).
