The accuracy of both methods will be in? Some higher-than-standard thicknesses may be impractical or unattainable. Except for local excess coating thickness which would interfere with the use of the product, or make it dangerous to handle edge tears or spikesrejection for nonuniform coating shall be made only for plainly visible excess coating not related to design factors such as holes, joints, or special drainage problems see Note 6.

In such cases, the precision and accuracy of the coating thickness measuring technique should be taken into consideration when rejecting such articles for coating thickness below that required by this speci?

They do not address the matter of measured coating thickness variations that can be encountered because of different steels or different thicknesses of a given steel being used in an assembly.

Total Materia has allowed us to solve in a definite way all problems we had for the search of alternate materials in foreign countries. 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.

Last previous edition A — 01a. The adhesion shall be considered inadequate if the coating? NOTE 7—Items which are prepared for galvanizing by abrasive cleaning will generally develop a thicker coating with a moderately rougher surface.

Unless otherwise agreed upon between the galvanizer and the purchaser, or established within this speci? For more information on the ASTM designation system see our related article: 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.

By mutual agreement, the galvanizer is not prohibited from submitting the lot remaining after sorting and removing nonconforming articles without replacement of the nonconforming articles. In such case, the now-smaller lot shall be treated as a new lot for purposes of inspection and acceptance.

In the case of orders in inch-pound units, the measured value shall be converted to coating grade aastm by the use of Table 2. The asgm method for the new sample shall be selected by mutual agreement between the purchaser and galvanizer. 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.

ASTM specifications represent a consensus among producers, specifiers, fabricators, and users of steel mill products.

ASTM Standard List: Coated Steels

A specimen must be evaluated for each steel category and material thickness within the requirements for each specimen of the test article. These designations often apply to specific products, for example A is applicable to cold-heading quality carbon steel wire for tapping or sheet metal screws. New Developments in Total Materia 10 th January The weight of x386 per unit area thus determined is converted to equivalent coating thickness values according to Table 2 rounding up or down as appropriate.

The other values are based on conversions using the following formulas: If you feel 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.

Lumps, projections, globules, or heavy deposits of zinc which will interfere with the intended use of the material will a3866 be permitted. This new sample shall be measured using magnetic thickness gages which have been calibrated for accuracy against reference material thickness standards.

The pieces shall be handled so that after galvanizing they will not freeze together on cooling. Our mission is simple; to ashm Total Materia the one-stop place and first choice of engineers world wide.

These tests shall not be required unless strong evidence of embrittlement is present.

The galvanizing of separate reinforcing steel bars shall be in accordance with Speci? This article contains a list of standards that covers among other things: NOTE 4—The coating thickness grades in Table 1 represent the minimum value obtainable with a high level of con? 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 non-conforming articles, or to renovate the nonconforming articles in accordance with 6.

Gas Nitriding of Titanium Alloys: The thickness thus determined is a point value.

The result list consists of over ASTM metal standards. It is the responsibility of the purchaser to heat treat or otherwise allow for the possibility of such embrittling phenomena.

Materials and Manufacture 5. The minimum average coating thickness grade for any specimen shall be one coating grade below that required for the appropriate material category and thickness in Table 1.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. While most coating thicknesses will be in excess of those values, some materials in each category may be less reactive for example, because of chemistry or surface condition than other materials of the steel category spectrum.

Marks in the zinc coating caused by tongs or other items s386 in handling the article during the galvanizing operation shall not be cause for rejection unless such marks have exposed the base metal and the bare metal areas exceed allowable maximums from 6. For thickness testing purposes, articles whose surface area is greater than in. This standard is subject to revision at any astk by the responsible technical committee and must be reviewed every?
