How should I correct the Shore A hardness of the compound to obtain the requested IRHD Hardness of my finished part?
The correct method to obtain the expected result in terms of IRHD hardness is to measure the result obtained at the end of the transformation process, compare it with the tolerance limits and correct the compound formulation by the number of points necessary to 'center' the result. This operation must be carried out for each mixing recipe and for each transformation process.

Which is the difference between Shore A and IRHD Hardness test results?
Test results of tests performed with IRHD (ISO 48-2) are are similar to the ones obtained with Shore A test (ISO 48-4), especially for low hardness. However, they are not strictly the same. Indeed, depending on the shape of the part, we can regularly notice 2 to 5 points hardness difference between Shore A and IRHD measurement done on the part. This difference can even be extended to 10 points difference in extreme cases. In 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.
