The Shore A nano hardness measurement is a method for determining the hardness of elastomers and thermoplastic elastomers in the entire Shore A hardness measurement range from -5 to +100 Shore A. The method is based on the miniaturization of the measuring needle defined in the ISO 48-4 standard by a factor of 10. Due to the innovative surface detection, the measurements are independent of the geometry of the specimen. Compared to the standardized durometer penetration method, the Shore A nano does not require a flat measuring surface and a significantly smaller specimen thickness for precise measurement. Wall or coating thicknesses of 0.05 mm are sufficient for comparative measurements here. This makes it possible to measure very small specimens, right down to granules, without any problems.
The integrated optical crosshairs enable precise positioning even with complex finished part geometries.
The method is suitable for precise and reproducible Shore hardness measurement on finished parts of small wall thickness and / or complex geometry.
The measurements performed with the Shore A nano are comparable to standardized Shore A measurements according to DIN, ISO, ASTM and JIS standards.
