ASTM A – Withdrawn Specification for Zinc Coating (Hot-Dip) on Assembled Steel Products

The use of these trace elements is permitted provided that the bulk chemistry of the galvanizing bath is at least ASTM specifications represent a consensus among producers, specifiers, fabricators, and users of steel mill products. The other values are based on conversions using the following formulas: In the case of orders in SI units, the values in Table 1, shall be applicable as metric units in micrometres.

Where products consisting of various material thicknesses or categories are galvanized, the coating thickness grades for each thickness range and material category of material shall be as shown in Table 1.

In the case of orders in SI units, all testing and inspection 1 This speci? The test method for the a3886 sample shall be selected by mutual agreement between the purchaser and galvanizer.

Consultation between the designer, fabricator, and galvanizer at appropriate stages in the design and fabrication process will reduce future problems.

The weight of coating per unit area thus determined is converted to equivalent coating thickness values according to Table 2 rounding up or down as appropriate. Do not use testing carried out at edges or corners points of lowest coating adhesion to determine adhesion of the coating. In the case of any such article containing more than one material category or steel thickness range as delineated in Table 1, that article will contain more than one specimen see Fig. In the case of orders in inch-pound units, the measured value shall be asttm to coating grade units by the use of Table 2.

The pieces shall be handled so that after galvanizing they will not freeze together on cooling.

Introduction to Total Materia 7 th February However, by agreement the purchaser is not prohibited from making tests which govern the acceptance or rejection aatm the materials in his own laboratory or elsewhere. If a sample is taken as representing the lot for acceptance, the sample shall be taken at random from the lot without regard to the perceived quality or appearance of any individual unit in the lot being sampled.
