Indentation in Shore Hardness Testing refers to the deformation or mark made in the material being tested by the durometer plunger when a standardized force is applied. The indentation depth is then used to determine the hardness of the material.

In Shore hardness testing, the material being tested is placed on a flat and stable surface, and a durometer plunger is pressed against the material with a standardized force. The plunger makes an indentation in the material, and the depth of the indentation is measured. The hardness of the material is then calculated based on the depth of the indentation, the spring force of the durometer, and the type of Shore hardness test method being used (e.g., Shore A, Shore D).

NextGen’s Advanced Portable Shore Durometer System indentation depth during test method A is 2.5mm.
