S
I come back with further explanation what Sa and Ra really were.
- Sa is about cleanliness,refers to ISO8501-1
- Ra is about roughness, refers to ISO8503-1
Typically these are critial product parameters during surface preparation, regarding process parameters, there were various different items, besides the ones mentioned by Soma, such as spraying angle, distance of spraying gun, humidity and so on.
Hope it will help you.
