In this case, the minimum number of specimens from each lot shall be as follows: The weight of coating per unit area thus determined is converted to equivalent coating thickness values in accordance with Table 2 rounding up or down as appropriate.

Marks in the zinc coating caused by tongs or other items used in handling the article during the galvanizing operation shall not be cause for rejection unless such marks have exposed the base metal and the bare metal areas exceed allowable maximums from 6.

The elements can be added to the galvanizing bath as part of a pre-alloyed zinc feed, or they can be added to the bath by the galvanizer using a master feed alloy.
