Shore hardness test guide: which scale to choose?
Reasons why you use incorrectly your analog Shore hardness tester.
You often hear of Shore A and D hardness scales… but are these the only ones?
Unfortunately, no.
In fact, they are much more than you imagine, here they are: A, B, C, D, DO, E, AO, O, OO, OOO, OOO -S, M and AM.
There’s a reason for all this variety, though.
You should know, in fact, that Shore hardness test scales refer to a specific hardness range: usually D scale is used for hard plastics, while A scale is used for less rigid ones.
And so far, nothing new.
But the fact is that polymers and elastomers are of various kinds – let’s think about gums and gel-like materials, for example – and relying only on two scales inevitably leads to inaccurate results.
How to choose, then?
