Description:This standard instead of gb/t 2411-2411 "plastic shaw hardness test method.
this standard specifies two type of hardness tester is used to test plastic and hard rubber indentation method, in which a model used for soft material, d type used for hard material. This method can measure initial indentation hardness or after a specified time of indentation hardness or both.
this standard as a kind of quality control test method, the determination of indentation hardness and subjects No simple corresponding relationship between material basic performance.
this standard and gb/t 2411-1980, compared with the main changes are as follows:
- change the name of the standard, increase the preface;
- to expand the scope of application, increasing the hard rubber;
