Purchasers desiring a guarantee of heavier coatings than the minimum thicknesses shown herein should use the aastm requirements see 4. Total Materia remains the only tool which will be used for this purpose. Originally published as A — 28 T. Such a plan is contained in Test Method B which addresses sampling procedures for the inspection of electrodeposited metallic coatings and related?

In the case of any such article containing more than one material category or steel asfm range as delineated in Table 1, that article will contain more than one specimen see Fig. By simply clicking the materials hot link, you can see a list of metal materials defined by the selected standard. The adhesion shall be considered inadequate if the coating? Coated steels Standard Number. Since surface smoothness is a relative term, minor roughness that does not interfere asgm the intended use of the product, or roughness that is related to the as-received un-galvanized surface condition, steel chemistry, or steel reactivity to zinc 5 6.

New Developments in Total Materia 10 th January 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.

Current edition approved October 10, 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.

NOTE 3—The galvanizer may choose to add trace amounts of certain elements for example, aluminum, nickel, and tin to the zinc bath to help in the processing of certain reactive steels or to enhance the cosmetic appearance of the? It is the responsibility of the purchaser to heat treat or otherwise allow for the possibility of such embrittling phenomena. A superscript epsilon e indicates an editorial change since the last revision asmt reapproval. For thickness testing purposes, the entire surface area of each unit of product constitutes a specimen.

A specimen must be evaluated for each steel category and material thickness within the requirements for each specimen of the test article.

Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Inchpound units and SI units are not necessarily exact equivalents. Practice A provides guidance on steel selection and discusses the effects of various elements in steel compositions for example, siliconthat in?

Likewise, do not use removal of small particles of the coating by paring or whittling to determine failure. These designations often apply to specific products, for example A is applicable a36 cold-heading quality carbon steel wire for tapping or asttm metal screws. Terminology A contains other terms and de? However, by agreement the purchaser is not prohibited from making tests which govern the acceptance or rejection of the materials in his own laboratory or elsewhere.

The other values are based on conversions using the following formulas: Within seconds it is also possible for you to find related detailed material property data or search equivalent materials starting from the Total Materia standard list.

This standard has been approved for use by agencies of the Department of Defense. Our mission is simple; to make Total Materia the one-stop place and first choice of engineers world wide.

Such inaccessible areas, for example, would be the internal surfaces of certain tanks, poles, pipes, tubes, and so forth. 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. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

For each specimen as described in 3. In such case, the now-smaller lot shall be treated as a new lot for purposes of inspection and acceptance. Unless otherwise agreed upon between the wstm and the purchaser, or established within this speci?

Practices AAand A provide guidance for steel fabrication for optimum hot dip galvanizing and shall be complied with in both design and fabrication. The minimum average coating thickness grade for any ashm shall be one coating grade below that required for the appropriate material category and thickness in Table 1.

The result list consists of over ASTM metal standards. Visual inspection of the coating shall be made for compliance with the requirements. The aztm of both methods will be in? In the case a3386 orders in SI units, the values in Table 1, shall be applicable as metric units in micrometres. The weight of coating per unit area thus determined is converted to equivalent coating thickness values in accordance with Table 2 rounding up or down as appropriate.

Minimum average thickness of coating for any individual specimen is one coating grade less than that required in Table 1. In the case of an article containing more than one material category or steel thickness range as delineated in Table 1, that article will contain a86 than one specimen, as appropriate see Fig. ASTM specifications represent a consensus among producers, specifiers, fabricators, and users of steel mill products. Total Materia has allowed us to solve in a definite way all problems we had for the search of alternate materials in foreign countries.

If Test Method B is used, the level of sampling shall be agreed upon between the galvanizer and the purchaser at the time the coating order is placed.
