Hello everybody!;)

I am working with a new mixture of natural refrigerants which have thermodynamic properties so interesting. I mean, it have been worked with a better energy efficiency and in general excellent results in a traditional system for R134a, so I would like to evaluate the compatibility of the mixture with different materials like plastics and elastomers for to know if I can recommend it as a new potential substitute of the conventional refrigerant 134a.

My question is how can I measure and evaluate the compatibility between materials solids with refrigerant? :confused:

I have read about ASTM standard for to evaluate it, but I need something else, do you have some idea or some information about it?

Thanks a lot.
