区别在于压针的形状不同，SHORE A用的是圆台形的针，而SHORE

Pressure difference is the shape of the needle, SHORE A with the truncated cone of the needle, and using a SHORE D is conical needle. <br>Therefore, to test A soft plastics, elastomers and rubber materials, and D for hard plastic with high hardness elastomeric rubber material; only when the measured value is greater than 90 A, to D-type, and when the D-type reading is type a is less than 20. <br>SHORE A 10-90, when the time change SHORE A 90 SHORE D. <br>Shore A and Shore 00 durometer are two types, Shore A rubber-like test, Shoer 00 foamed material is a low hardness test type. Both did not change the number of formula ..

The difference is that the needle is shaped differently, SHORE A uses a round pin, and SHORE D uses a cone-shaped needle.<br>So A is used to test soft plastics, elastomers and rubber materials, D is used for hard plastics and high hardness elastomers and rubber materials;<br>SHORE A 10-90, when SHORE A 90 is changed to SHORE D.<br>Shore A and Shore 00 are hard gauges for both models, Shore A is tested for rubber, and Shoer 00 is a test of low-hardness foaming materials.

The difference is that the shape of the pressing needle is different. Short a uses a circular table needle, while short D uses a conical needle.<br>So a is used to test soft plastics, elastomers and rubber materials, and D is used to test hard plastics and high hardness elastomers and rubber materials. Only when the measurement value of a is greater than 90, it is changed to type D, and when the reading of type D is less than 20, it is used to type A.<br>Short a 10-90, when short a 90, change to short D.<br>Shore A and Shore 00 are two types of hardness tester. Shore A is used to test rubber, and Shore 00 is used to test low hardness foaming materials. There is no formula for replacement between them.<br>
