SpletIn general, IRHD results are lower to Shore A results. That is why it is common to use “75 Shore A compounds” to obtain “70 IRHD part”. For example, parts moulded with a “70 Shore A compound” can give finished parts with a hardness from 62 to 65 IRHD, and therefore out of the 70±5 IRHD tolerance.
