** Spring load of outer ring to create constant pressure when outer ring is pulled to red marking
The principle used to measure textile hardness is based on measuring the resistance force of the penetration of a ball shaped indentor against the spool under a known spring load. The hardness scale covers a range of 0 – 100, were 0 is the smallest and 100 is biggest hardness. The measuring force and the principle relates to the specifications of rubber hardness tester Shore A.
There exists no international standard for adjusting and calibration of textile hardness. Therefore we have developed our own test-standard and procedures.
