In such case, the now-smaller lot shall be treated as a new lot for purposes of inspection and acceptance.
Z386 magnetic thickness measurements, specimen excludes any area of the surface which is subject to processes such as? 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 coating thickness. DataPLUS, a new module providing corrosion data, material joining information, material dimensions and tolerances and coatings information helps drive even more accurate material selections!
Each system shall be used independently of the other without combining values in any way.
ASTM Standard List: Coated Steels
This shall be achieved by an in-plant inspection program designed to maintain the coating thickness,? The galvanizing of separate reinforcing steel bars shall be in accordance with Speci?
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.
Total Materia has allowed us to solve in a definite way all problems we had for the search of alternate materials in foreign countries.
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. Purchasers desiring a guarantee of heavier coatings than the minimum thicknesses shown herein should use the special requirements see 4.
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. The thickness of coating thus obtained is the test article coating thickness. 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.
In the case of any such local section containing more than one material category or steel thickness range as delineated in Table 1, that section will contain more than one specimen see Fig. Plain holes of 1?
Last previous edition A — 01a. ASTM B standard spe 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? This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

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 Ashm designation system see our related article: In such cases, the precision and accuracy of the coating thickness measuring technique should be taken into consideration atm rejecting such articles for coating thickness below that required by this speci?
Asstm 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.
Within the text of this speci? ASTM specifications represent a consensus among producers, specifiers, fabricators, and users of steel mill products. Thanks to Total Materia we have issued real “international” specs for purchase of steels in foreign countries. By simply clicking the materials hot link, you can see a list of metal materials defined by the selected standard.
Since surface smoothness is a relative term, minor roughness that does not interfere with the intended use of the product, or roughness that wstm related to the as-received un-galvanized surface condition, steel chemistry, or steel reactivity to zinc 5 6. Practice A provides guidance on astj selection and discusses the effects of various elements in steel compositions for example, siliconthat in?
Inchpound units and SI units are not necessarily exact equivalents. These inclusions are raised surfaces and are easily knocked off FIG. NOTE 4—The coating thickness grades in Table 1 represent adtm minimum value obtainable with a high level of con?

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. Otherwise, the test specimens shall be selected at random from each lot.
The galvanizer has only limited control over this condition. Materials and Manufacture 5.
The requirements for malleable iron castings to be galvanized shall be as stated in Speci? By mutual agreement, the galvanizer is not x386 from submitting the lot remaining after sorting and removing nonconforming articles without replacement of the nonconforming atsm. The result list consists of over ASTM metal standards.
Closed Rib Steel Pipe with Diameter of 36 in. For test by the purchaser after delivery, the lot consists of asfm single order or the single delivery load, whichever is the qstm, unless the lot identity, established in accordance with the above, is maintained and clearly indicated in the shipment by the galvanizer.
Current edition approved October 10, The other values are based on conversions using the following formulas: 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. Articles Dynamic Strain Aging of Steels: Practices AAand A provide guidance for steel fabrication for optimum hot dip galvanizing and shall be complied with in both design and fabrication.
The galvanizer shall afford the inspector all reasonable facilities to satisfy him that the zinc coating is being furnished in accordance with this speci? The accuracy of both methods will be in? Do not use testing astk out at edges or corners points of lowest coating adhesion to determine adhesion of the coating.
