NOTE 9—Although some material may be formed after galvanizing, in general the zinc coating on the articles covered by this speci? If the lot is found to be nonconforming by the new sample, the galvanizer has the right to sort the lot for conforming articles by individual test, to re-galvanize nonconforming articles, or to renovate the nonconforming articles in accordance with 6.
Such a plan is contained in Test Method B which addresses sampling procedures for the inspection of electrodeposited metallic coatings and related? Unless otherwise agreed upon between the galvanizer and the purchaser, or established within this speci? For purposes of this speci?
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.
NOTE 7—Items which are prepared for galvanizing by abrasive cleaning will generally develop a thicker coating with a moderately rougher surface.
ASTM Standard List: Coated Steels
Thanks to Total Materia we have issued real “international” specs for purchase of steels in foreign countries. Practices AAand A provide guidance for steel fabrication for optimum hot dip galvanizing and shall be complied with in both design and fabrication. The other values are based on conversions using the following formulas: If a zinc alloy is used as the primary feed to the galvanizing bath, then the base material used to make that alloy shall conform to Speci?
The test method for the new sample shall be selected by mutual agreement between the purchaser and galvanizer. The mass, shape, and amount of cold working of the product being galvanized may also affect this astk.

By simply clicking the materials hot link, you can see a list of metal materials defined by the selected standard. The thickness of coating thus obtained is the test article coating thickness, or in the case of a specimen removed from a test article, is the specimen average a86 thickness.
In the case of orders in inch-pound units, the measured value shall be converted to coating grade a3886 by the use of Table 2.
Plain holes of 1? 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.
