Sponge foam tear strength elongation tester servo system operation

Sponge tear strength tester is a testing machine used to test tensile strength, elongation after fracture, tear strength, indentation ratio and indentation hardness of polyurethane, car seats, soft foam polymers and other sponge materials. It can meet a variety of national standards and standards, such as GB/T10807-2006, ASTM D3574, ASTM D3574, GB/T6344-1996, GB/T10808-2006, ISO8067:1989 and so on.

Sponge tear strength tester is usually composed of frame, tensile device, tear device, measuring device, data processing device, etc. During testing, the sponge material to be tested is placed on a testing machine, tearing behavior in actual use is simulated by a stretching device and a tearing device, tensile force and tearing degree are recorded by a measuring device, and performance indexes such as tearing strength of the sponge material are calculated by a data processing device.

When using the sponge tear strength tester for testing, the following points need to be noted:

1. The tested materials shall comply with relevant national standards and standards to ensure the accuracy of test results.

2. When installing and debugging the tester, it should be operated according to the requirements of the manual to avoid damage or error caused by improper operation.

3. During the test, the tester should be kept clean and dry to avoid affecting the test results.

4. During use, regular inspection and maintenance should be carried out to ensure the normal operation and service life of the tester.
