The principle used to measure the “firmness” or “hardness” of textile material is based on
measuring the resistance force of the penetration of a ball sensor into a bobbin under a
constant spring load. This principle is based on the Shore hardness test procedure.
The display range of the textile durometers covers a range from 0 to 100 units, where 0
corresponds to the minimum and 100 to the maximum hardness value.
These units have no formal industry standards or engineering classification, and are not
related to a specific Shore value or other known value. Since there are no international
standards that can be used to compare against, we have developed a special test proce-
dure for verifying calibration (see Chapter 3.2).
