Likewise, do not use removal of small particles of the coating a836 paring or whittling to determine failure. This shall be achieved by an in-plant inspection program designed to maintain the coating thickness,? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Some higher-than-standard thicknesses may be impractical or unattainable.

NOTE 9—Although some material may be formed after galvanizing, in general the zinc coating on the articles covered by this speci? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

If you x386 that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. The elements can be added to a3886 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.

Total Materia remains the only tool which will be used for this purpose.

Finding ASTM materials and standards from specific designation systems in the Total Materia aastm With Total Materia finding information about a metal standard specification, its current status and the materials it defines is one click away. Therefore, some articles may have a coating grade at or close to the minimum requirement shown in Table 1.

NOTE 1—Each specimen comprises nominally one third of the total surface area of the article.

For test by the purchaser after delivery, the lot consists of the single order or the single delivery load, whichever is the smaller, unless a36 lot identity, established in accordance with the above, is maintained and clearly indicated in the shipment by the galvanizer. These inclusions are raised surfaces and are easily knocked off FIG.

A specimen must be evaluated for each steel category and material thickness within the requirements for each specimen of the test article. ASTM specifications represent a consensus among producers, specifiers, fabricators, and users of steel mill products. 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.


If the lot size is such that the sample size cannot be doubled, then the sample size shall be as previous, but the number of widely dispersed sites at which measurements were made shall be doubled, and these sites will constitute the new sample.

The average of no less than? For thickness testing purposes, the entire surface area of each unit of product constitutes a specimen.
