This test method provides a standard method of determining the weight [mass] of coating for comparison with specification requirements. A coating of aluminum on iron or steel articles provides protection against corrosion by forming a relatively inert barrier. Specifications for aluminum-coated articles occasionally provide for different classes (weights) [masses] of coating so that the purchaser can select the coating weight [mass] most suited to his or her needs. The heavier coating will provide greater protection against mechanical damage which may break the coating.
