So, the terminology used here is "refrigerant grade" also "laboratory grade".
The R-22 organic replacement is implicitly refrigeration grade.
This page spells out purity specifications, and also
this page has documents that spell out safety precautions, etc.
I think that you just need to find the local name for the organic R-22 replacement refrigerant.
BTW, I was never able to get a response from the Chinese Brazed Plate company.
