Flange Bolt Corrosion

I am looking for information regarding bolt discard criteria for flange bolting that has been affected by corrosion. Are there any standards or rules that can be applied after a close visual examination of the bolt in situ?

Flanges are in petroleum pipework, mainly constructed to ANSI B31.3.
