One of the most important and widely used types of mechanical testing of materials is tensile or tension testing. When using a tensile strength tester, a tensile force or stress is applied to a material until it fails or fails, and the response to the load is measured. Through this test, we can determine the strength of a material and measure the amount of force required to stretch it.
Type of tensile test
There are different types of tensile tests, including:
1. Adhesion or bonding strength test
This type of tensile test measures the strength of a coating’s bond to a surface or object. This test is commonly associated with seal strength for adhesives, laminates, tapes, sealants, electronics, and general packaging.
2. Crimp tensile test
Also known as the crimp pull test, this test uses a pull tester to measure the pulling force required to remove a crimped ferrule, connector, or terminal from a wire. This is typically done on the production line as part of a life cycle assessment or along with the electrical integrity of the electrical wiring.
3. Peel test
A peel test is performed to measure the adhesion or cohesion between two materials of her that are joined with an adhesive. It measures the resistance to peeling from each other after the adhesive has been applied to the tensile specimens. The value determined determines whether the bond is sufficient or too strong for the intended application, or whether a different adhesive or bonding method should be used.
4. Tear strength test
This test uses a tensile tester to apply force to an article that already has an incipient tear until it completely fails or breaks. This test measures tear strength, or the ability of a tensile specimen to resist propagation of a partial tear. This is commonly used on flexible materials that are prone to accidental tears or punctures. Such materials include fabrics, textiles, polymers, rubbers, elastomers, packaging, and paper products.
The Importance and Benefits of Tensile Testing
- Preparation of soft, hard, and metal tensile specimens
- Performance and strength data measured by tensile testers are critical in design and material selection, product trading, new product development, quality control, and equipment safety.
- During the research phase of product development, tensile testing is important to select the most suitable materials. A tensile tester can confirm that a candidate material meets the strength and elongation requirements required for a particular product.
- In the metal industry, tensile testing offers an opportunity to discover new alloys, their qualities, and possible uses. This could lead to improved materials that benefit both manufacturers and end users.
- The use of tensile strength testers in product quality control is also important. It provides manufacturers with a way to identify if there is a problem on the production line. We also ensure that what we deliver to our customers is safe, of high quality, and compliant with industry and international standards.
- The cost of not meeting industry standards isn’t just financial. At worst, it can incur human costs. Regular tensile testing is usually much cheaper than using the wrong material or selling an inferior product. Therefore, performing reliable and accurate tensile tests should be a priority.
