Application examples
with equipment

O-ring on turntable K with angle adjustment from 0 ° -90 °

This combination is for rotationally symmetrical components, such
as O-rings and Simmerrings are particularly well suited. The
three-jaw chuck enables flexible clamping variants and thus also
measuring in the normal direction.

Samples on linear axis type X

The linear axis is available individually or can be stacked as an XY variant with 80 mm travel.
Several or individual measuring points can be measured fully automatically on several test objects.

Frequently asked questions about the IRHD-M process

IRHD stands for International Rubber Hardness Degree [°] that can be measured with this method. The M in IRHD-M stands for micro, which means that very small rubber samples and products with a thickness of 1 mm or more can be determined. It can therefore be determined how hard small elastomer, plastic or rubber products, e.g. O-rings or coatings, are. In addition, there are the IRHD processes in the N, H, L, M and VLRH versions.

The degree of hardness provides information on the deformation behavior as a result of a constant load and can therefore provide conclusions about the functionality of small parts. The geometry of the test body is a sphere, which is why we often speak of the ball indentation hardness IRHD.
