>> Tensile Strength Tester
A device that measures a material's ability to resist breaking under traction.

>> Other information
Tensile strength is a material's ability to resist breaking under tension. By testing the tensile strength you will know what a material's "ruggedness" really is. It is an important mechanical property when it comes to polymers, fibers, rubber, metals and etc.It is often referred to as tensile strength or breaking strength and with Newton units per area (mm2 or inch2).
♦ Formula

Tensile strength = L / A

Basically all tensile testing machines do not change significantly. According to different standards and different test pieces, they have some differences in maximum load, accuracy, grip, load cell, and other aspects. When you want to test the tensile strength of metal samples, the maximum load should be large and it may not need very high accuracy. But if you do anything to test the tensile on a thin film, maybe 5N is enough.
Speaking of tensile strength, there is another definition that should be discussed together - Elongation, which is just the length of the polymer sample after it has been elongated (L), divided by the initial length of the sample (L 0). , and then multiply by 100.

L / Lo x 100 =% elongation

Here mainly talk about the testing of tensile strength and elongation speed. Flexible plastics like polyethylene and polypropylene differ from rigid plastics in that they are not deformed resistant, but they tend not to break. Of course, the ability to deform is what prevents them from breaking. Initial modulus is high, that is it will resist forawhile deformation, but if enough Tensile force is applied on a plastic, it will eventually deform. You can try it at home with a plastic bag. If you try to stretch it, it will be very difficult at first, but once you've stretched it far enough it will give way and stretch easily.

♦ International testing standards for materials (plastics, adhesives) - Tensile and elongation test
The same test for measuring tensile in the ISO system is ISO 527. Values ​​reported in the tests of ASTM D638 and ISO 527 generally do not vary significantly and the test will provide good results in the process. material selection process. A separate tensile test method is commonly used for polymer films (ASTM D882) and elastomers (ASTM D412).
