The IRHD technique was created within ISO so as to improve the accuracy in measuring hardness. This technique is known as International Rubber Hardness Degrees or IRHD. The scale for IRHD equipment corresponds to Shore A. What differentiates the techniques is that the IRHD equipment is always mounted on a stand, the loading is performed with a deadweight, the measuring probe is ball-shaped, and the reading is taken after 30 seconds. Digital tutor school automatic hardness meter with exchangeable measuring probes for Shore A, D, AM IRHD-N and IRHD-M. (Photo: Bareiss) Pusey & Jones hardness meters are generally used to measure the hardness of larger rubber covered rolls, since the device can be used on curved surfaces. The device has a tripod stand, which is positioned on the surface that is to be measured. A 3,175 mm ball is pressed with a constant weight of 1000 g into the rubber surface and the result is provided in 1/100 mm. Pusey & Jones hardness meter.
