Introduction to the performance and strength requirements of the tensile tester for fixtures

The fixture isTension testerThe key to testing the material of the tensile tester is to choose the fixture of the test machine. The following is a detailed explanation of the performance of the fixture.

Requirements for fixture structure. The design of the fixture is mainly based on the test standards of the material and the shape and material of the sample (specifically referred to as finished and semi-finished products). The above test standards refer to ISO, ASTM, DIN, GB, BS, JIS, etc., as well as enterprise standards, industry standards, etc. These standards generally have strict regulations on sample preparation and test methods. We can design different fixtures according to the different samples and test methods. For fixtures used for special samples (finished and semi-finished products), fixtures are mainly designed based on the shape and material of the sample.

The sample is clamped by clamping the sample (or product) and the amount of the test force that the fixture can withstand is a very important indicator of the fixture. It determines the size of the fixture structure and the labor intensity of the fixture operation. The sample materials are divided into metal and non-metal, and the shapes are divided into sizes. The composition of the material is various. The test force that the sample can withstand is as small as a few dozen centimeters (such as spandex wire for textiles), to as large as a few dozen tons, such as ordinary steel, and other domestic electronics.Universal testing machineThe test force is 1000KN, 1st grade machine, the sample size is as small as a gold wire with a diameter of φ0.005mm, and the PVC pipe with a diameter of 1.5m, etc. This requires the selection and design of different fixtures according to different test forces and the shape and size of the sample.
