In order to save the hardness of plastics, Albert Shore devised a simple procedure in 1915: a metal tip of a defined shape is pressed against the sample by a spring.
The depth of the impression is then used to determine the hardness or softness of the material. This procedure is described in DIN ISO 7619-1:2012.
Nowadays, two main types of devices are used: Mechanical measuring devices with a pointer and electronic measuring devices.
Both types of measuring devices can be used with test stands. A test bench allows for significantly more accurate and consistent measurements.

What is a hardness tester and why is it important?
A hardness tester is a device used to measure the resistance of a material to indentation or deformation. It is an important tool in the manufacturing industry as it helps to ensure that products meet the necessary quality and safety standards. By measuring the hardness of materials, manufacturers can identify any defects or inconsistencies that could affect the product’s performance. Hardness testers are also used to monitor the quality of raw materials and finished products, helping to ensure that they meet the necessary specifications.
Hardness testers are an essential tool in the manufacturing industry, where they are used to ensure the quality and durability of products. They are commonly used to test the hardness of metals, plastics, and other materials used in manufacturing processes. By measuring the hardness of these materials, manufacturers can ensure that their products meet the necessary safety and performance standards. Hardness testers are also used to monitor the quality of raw materials and finished products, helping to identify any defects or inconsistencies that could affect the product’s performance.
