Mechanical surface stiffness of elastomeric materials is determined using measuring systems that record the penetration of a defined indenter under controlled force. In Micro-Shore A and IRHD-Micro testing, the penetration depth of a standardized indenter into materials such as rubber or other elastomers is measured with high precision. A hardness testing device enables this measurement under reproducible conditions and provides quantitative values for evaluating material properties, quality, and aging behavior. Micro-hardness testing is particularly advantageous for thin samples, small components, or localized material analysis due to its high measurement accuracy and comparability.
