Ⅰ. Major performances
Shore rubber hardness gauge is an apparatus to measure vulcanized rubber and plastic products. This apparatus has three models of Type A, Type C and Type D, and each model is subdivided into two types of single pointer and double pointer.Type A and D respectively are applicable to the Testing of low and medium hardness, and high-hardness materials. Type C applies to the Testing of microporous material which is used to make shoes, with compression rate 50 percent, stress 0.049 MPa or above, and this kind of material is made of rubber plastic and has blister in plastic.
This hardness gauge conforms to the regulations of GB/T531-99, GB2411-80, hg/t2489-93, JJG304-2003.
