The quality control of the corrosion protection

Do you know of a standard (European or American) for the quality control of the corrosion protection (hot galvanizing, painting or zinc plating with bichromate) on steel pipes and pieces? I mean the controls to carry out externally - not by the manufacture - on site at the reception of the components.

Thanks for your help.

First of two simultaneous responses --

Theoretically the same quality control used by the manufacturer would have to be followed by the buyer (or vice versa) in order to make a wise comparison and take a fair action. Measuring in a different way or using a different standard only causes trouble and disputes. That's what ISO standards intend to do.

Try British Standard 729 . It should have it.
