Mooney-Rivlin Testing

I have read comments many comments that it is better to test for elastomeric data and place the information into Solidworks® Non-linear, M-R (Mooney-Rivlin), Simulation™.  It is my understanding that this will yield more accurate results.  Also, the M-R constants, C1 & C10, could be generated from this supplied data for future use.  I have also heard that the part should be tested.

 

This is well and good.  However, we not only use standard round O-rings, but more importantly some complex O-ring cross-sections, which I might describe as a 'spider's web'.  So, not why, but how do I test to get the data to place into Solidworks Simulation.  With metal or plastic, we make dogbone tensile samples.  With elastomers, how do we get this data?  Compression testing of a cube of the material; the actual part?  All thoughts appreciated.
