The latest regulations for universal testing machine instruments in 2012

The test machine has test equipment with the measurement technical specifications of relevant national departments. It has different regulations on different materials and needs. Our company is based onUniversal testing machineThe standards list the standards formulated by the state, and the changes are as follows:

1) The scope has been expanded and the "electronic tensile testing machine" and "electronic pressure testing machine" are also included in this standard (Chapter 1 of the 1996 edition; Chapter 1 of this edition);

2) A term was deleted (1996 edition of 3.1);

3) Modified some of the contents of "Table 1 symbols" (Table 1 of the 1996 edition; Table 1 of this edition);

4) Modified some contents of the main parameter series (Chapter 4 of the 1996 edition; Chapter 4 of this edition);

5) The two levels of level 2 and level 3 in the test machine classification were cancelled (5.2 of 1996; 5.2 of this version);
