A standard specimen (also known as a test specimen) is an object with specific properties that is used for materials testing. The standard sample consists of the material to be tested and is intended to provide information about its properties.
The standard sample is precisely defined in terms of dimensions, shape and composition. Depending on the type of material, standards specify which geometry and dimensions the standard sample must have.
Standard samples are used for the following test methods, among others.
Tensile test
Pressure test
Shear test
Hardness test
#1 Definition of standard sample
Standard specimens are bodies of defined geometry and dimensions that are made of a specific material. They are subjected to tests to determine the material properties of the material.
#2 Applications of the standard sample
Many quality tests are used in sealing technology that require a standard sample of the sealing material. These include determining the compression set, hardness testing and tensile testing.
Finished parts may deviate from the material properties determined on standard samples, as dimensional and geometric differences influence the results.
