The accuracy of electronic tensile testing machine data refers not only to the testing accuracy of the device itself, but also to the operational quality of the testing machine operator. When the test accuracy of the instrument itself is stable, the testing machine operator must also pay attention to the following points to improve the accuracy of the test data of the electronic tensile testing machine.

1. Does the design of the bracket of the electronic tensile testing machine make sense?QsdTextile Testing Instruments, Testing Equipment Manufacturer

The bracket of the electronic tensile testing machine is also a very important part. QsdTextile Testing Instruments, Testing Equipment Manufacturer

Second, whether the electronic tensile testing machine has been reset before testingQsdTextile Testing Instruments, Testing Equipment Manufacturer

The electronic tensile testing machine has a memory function, the test data ware mixed with the data of this test, so that the calculation of the testing machine system is not accurate enough. QsdTextile Testing Instruments, Testing Equipment Manufacturer

3. Whether the specimen is properly restrainedQsdTextile Testing Instruments, Testing Equipment Manufacturer

The specimen restraint is a very important link in the testing process. When the specimen is properly restrained, during the straining process, the test The specimen only bears the pulling force in the up and down directions, and the test results at this time are accurate. If the sample is clamped askew, the sample will be subjected to tensile forces in multiple directions and the test results will naturally be inaccurate.

Fourth, whether the tensile speed of the electronic tensile testing machine conforms to the standardQsdTextile Testing Instruments, Testing Equipment Manufacturer

Generally, each material has a corresponding testing standard, which indicates its tensile strength. If the strain rate is too fast or too slow, the test data will be different. If you want to improve the accuracy of the test data, müsset the strain rate strictly according to the test standard. QsdTextile Testing Instruments, Testing Equipment Manufacturer
