This is used more commonly with Method B where voltage may vary from test to test but can adtm be used for veri? Summary of Test Methods 4. Procedure for Method B This method will not, however, find any thin spots in the coating. Take care to keep the electrolyte at least These are used on the coatings of relatively high-electrical resistance when such coatings are applied to the surface of materials of low-electrical resistance, such as steel pipe.

A number in parentheses indicates the year of last reapproval. It should be noted, however, that this method will not detect thin spots in the coating, even those as thin as 0.
