Indentation Hardness Tester

Indentation Hardness Tester for rubberized coir cushioning is used for the indentation hardness measurement of foam, PU foam, rubberized coir and latex foam. The system consists of a shear beam type load cell over which the test specimen is kept. The test specimen is pressed with an indentor of the specified dimension mounted on self/ aligning ball bearing such that it can adjust its inclination to match the top face of the test specimen. The indentor can be moved down manually through a hand wheel (as well as by motor and gear box) and screw arrangement, thickness is measured on strip scale and Compression is measured on a digital indicator and the corresponding load is measured on the digital readout of the load cell.

Technical Specification:

• IS 8391 – 1977:specification for rubberized coir sheets for cushioning
• IS 11060 – 1984: Specification for moulded rubberized coir cushioning
