WHICH DIAPHRAGM TEST

[ta5ari]

I am using a sheet of rubber to arrange diaphragms. The material is in sheets 0,7 mm thick and it is made of NBR with PA66 reinforcement cloth inside.
I would like to have suggestions about the tests which I should implement in order to ensure the stability and quality of the material as different batches are received.
thanx a lot

It is difficult to give you useful feedback with so little info. If you tell me bit more about the application of the diaphragm then I might be able to give you a better answer.
