The performance and strength data measured by tensile testers are important in the selection of design and materials, purchase and sale of products, development of new products, quality control, and safety of equipment.

During the research stage of product development, tensile testing is crucial in choosing the most appropriate materials. A tensile test machine can verify whether candidate materials pass the required strength and elongation requirements for a certain product.

In the metals industry, tensile testing provides an opportunity to discover new alloys, their qualities, and the possible uses they might have. This can lead to improved materials, which are beneficial to both manufacturers and end users.

The use of a tensile strength tester in the quality control of products is also crucial. It provides manufacturers a way to identify whether there are problems in their manufacturing line. It also ensures that what they deliver to customers is safe, of high quality, and adheres with industry and international standards.

The cost of not complying with industry standards may not only be monetary. At worst, it could involve human cost. Performing regular tensile testing usually costs far less than the consequences brought about by using inappropriate materials or sale of substandard products. Therefore, carrying out reliable and accurate tensile tests should be a priority.
