Durometer according ISO 7619-1 for determining the Shore surface hardness of foams, steering wheels and inner linings of motor vehicles with hardness < 20 Shore A
For measuring the hardness, the spring-loaded outer ring of the housing is pressed downwards until the edge of the ring meets the colored marking on the housing. This ensures a constant pressure and prevents measuring errors.
General:
The principle used to measure shore hardness is based on measuring the resistance force of the penetration of a pin into the test material under a known spring load. The amount of penetration is converted to hardness reading on a scale with 100 shore units.
As the depth of indentation is max. 2.5 mm the test material has to have a minimum thickness of 6 mm. If thickness is less, stack some samples till you reach the required thickness.
The HP series durometer is supplied as a complete kit with:
A calibration certificate is optional.
