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.
ASTM Standard List: Coated Steels
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Practices AAand A provide guidance for steel fabrication for optimum hot dip galvanizing and shall be complied with in both design and fabrication.
The accuracy of both methods will be in? 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.
Dynamic Strain Aging of Steels: It is the responsibility of the purchaser to heat treat or otherwise allow for the possibility of such embrittling phenomena. In such cases, the precision and accuracy x386 the coating thickness measuring technique should be taken a836 consideration when rejecting such articles for coating thickness below that required by this speci?
Within the text of this speci? The result list consists of over ASTM metal standards. 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.
For more information on the ASTM designation system see our related article: 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.

While most coating thicknesses will be in excess of those values, some a86 in each category may be less s386 for example, because of chemistry or surface condition than other materials of the steel category spectrum.
Release DataPLUS, a new module providing corrosion data, atsm joining information, material dimensions and tolerances and coatings information helps drive even more accurate material selections! 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.
The adhesion shall be considered inadequate if the coating? Inspection, Rejection, and Retest 9. The test method for the new sample shall be selected by mutual agreement between the purchaser and galvanizer.
Enter a phrase to search for: 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?
ASTM AAM Standard Specification for Zinc_百度文库
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.
Introduction to Total Materia 7 th February Metallic coated carbon steel wire coated at size for mechanical springs Composite ribbed steel pipe, pre-coated and polyethylene lined sewer pipe application Flexible poly vinyl chloride PVC gaskets used in connection of water closets to sanitary drainage system For more information on the ASTM designation system see our related article: 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 more than one specimen, as appropriate see Fig.
Visual inspection of the coating shall be made for compliance with the requirements. In such case, the now-smaller lot shall be treated as a new lot for purposes of inspection and acceptance. Current edition approved October 10, Metallic coated carbon steel wire coated at size for mechanical springs Composite ribbed steel pipe, pre-coated and polyethylene lined sewer pipe application Flexible poly vinyl chloride PVC gaskets used in connection of water closets to sanitary drainage system.
This standard has been approved for use by agencies of the Department of Defense. Click here to see more. Coatings shall conform to the requirements of Speci? Do not use testing carried out at edges or corners points of lowest coating adhesion to determine adhesion of the coating. Plain holes of 1? 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. Introduction to Total Materia Integrator 7 th March A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Since surface smoothness is a relative term, minor roughness that does not interfere with 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.
