I have seen explainers like https://www.swep.net/refrigerant-handbook/5.-refrigerants/sd6/ and https://www.achrnews.com/articles/108910-ice-breaker-refrigerant-numbering-system-explained
But have not found any clear explanation of the lowercase "ze" and "yf" commonly seen suffixed in R1234ze and R1234yf.
I understand the uppercase parenthesized (E),(Z) suffixed like R1234ze(E) is used to specifically refer to the (E) isomer.
Does the lowercase "ze" suffix refer to the unspecified mixture of the 2 isomers?
What does "yf" mean?
