Grade 50 Mechanically Deposited Coatings
What does the designation "Class 50" mean for mechanically galvanized items.

Apparently it is an ASTM B695 specification which calls for a zinc coating mechanically galvanized, 500 salt spray hours, no topcoat.
But I don't have the specification in front of me. You might want to acquire (purchase) a copy.

How tight can plater hold b695 gr50 plating. I am looking for someone to hold a tolerance between 50 and 70 microns. Is this realistic or not. If not what tolerance would be?
Thank you in advance,
