This question has been bandied about in every shop that I worked in. There is no official answer that I'm aware of. Demand a marked up or initialed print. It's...- easymike299

Removing 4mm thick brake plates from magnetic chuck of a ring grinder
Lay a piece of clean, dry, unused paper between your ring and the magnetic chuck. Copy or tablet paper will do fine. The ring will be parallel within a couple of tenths if the paper is not wrinkled. Gene- easymike299
