About This Product
The softness of flexible foam is described by its indentation hardness. In the test, a circular indentor presses into a block of foam at a set speed, and the force needed to compress the block to a set percentage of its thickness is recorded. The result is used to compare foams, for example those used in seats. The tester is used in foam and materials testing labs.
Frequently Asked Questions
Q1. What is indentation hardness?
It is the quantitative measure of the feel of softness of a flexible foam. It is found as the force needed to compress a foam block to a specified percentage of its initial thickness.
Q2. How does the Indentation Hardness Tester stop the test?
It has an arrangement that stops the movement of the indentor automatically after the desired deflection.
