Scope

This Standard specifies principle, test solution, samples, test procedure, result
calculation, reproducibility and test methods for gravimetric determination of the mass
per unit area of galvanized coatings on steel products.
The galvanized coatings stated in this Standard include pure galvanizing coating,
zinc-iron alloy and aluminum-zinc coating (such as zinc -5% aluminum alloy coating
and 55% aluminum-zinc alloy coating). This Standard is applicable to steel products
such as hot dip galvanizing and electro-galvanizing which are easy for the
determination.
Methods in Appendix A also may be adopted for the mass test for the zinc coating of
galvanized steel sheets.
