AHT Hardness Measurement Detail
Shore A hardness measurements are based on the precise application of force and the subsequent measurement of probe displacement.
A 12.5 N weight is applied to the measurement device that consists of a hardened steel probe of a prescribed shape. The measurement is performed multiple times, with the sample being rotated automatically between measurements to ensure representative sampling. The individual values, and the mean and median for the specimen are reported for each.
