This product is available in four zinc-coating designations which are listed in Table 1. For electrolytic zinc-coated steel sheet with coating masses heavier than described in this speci? The coating is used to provide some enhancement in corrosion performance as compared to an uncoated product. It is not intended to withstand outdoor exposure without chemical treating and painting.


Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Current edition approved May 10, Originally published as A — Last previous edition A — The thickness is the total of the base aastm and the coating.

NOTE 1—A typical ordering description in inch-pound units is as follows: Aastm typical ordering description in SI units is as follows: If one surface is protected suitably during the initial stripping, coating mass can be determined for each surface independently. Conversion of the coating mass to coating thickness is possible only if the density of the coating is known precisely.

This method is readily adaptable to the continuous monitoring of coating mass during coating. Thus modern electroplating facilities are frequently equipped with X-ray? These devices are permitted for use as a basis for determining suitability for shipment provided that they have been calibrated properly.

The method is rapid and versatile for light coating mass applications. Flaking of the coating within 1? Flaking of coating within 1?
