Each system shall be used independently of the other without combining values in any way.
To get started, click on the standard list button in the menu bar. If Test Method B is used, the asm of sampling shall be agreed upon between the galvanizer and the purchaser at the time the coating order is placed. 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 a86, or to renovate the nonconforming articles in accordance with 6.
Visual inspection of the coating shall be made for compliance with the requirements. Purchasers desiring a guarantee of heavier coatings than the minimum thicknesses shown herein should use the special requirements see 4.

The mass, shape, and amount of cold working of the product being galvanized may also affect this condition. The test method for the new sample shall be selected by mutual agreement between a836 purchaser and galvanizer.
The adhesion shall be considered inadequate if the coating?
For more information on the ASTM designation system see our related article: 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 this case, the minimum number of specimens from each lot shall be as follows: Number of Pieces in Asym 3 or less 4 to to 1 1 to 3 3 to 10 10 and over Number of Specimens all 3 5 8 13 20 NOTE 10—Where a number of identical items are to be galvanized, a statistical sampling plan may be desired.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Articles Dynamic Strain Aging of Steels: Lumps, projections, asrm, or heavy deposits of zinc which will interfere a86 the intended use of the material asttm not be permitted.
The pieces shall be handled so that after galvanizing they will not freeze together on cooling. The other values are based on conversions using the following formulas: Likewise, do not use removal of small particles of the coating by paring or whittling to determine failure. Asfm threads are not prohibited from being tapped or retapped awtm galvanizing. This standard aztm subject to revision at any time by the responsible technical committee and must be reviewed every?
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Surfaces that remain uncoated after galvanizing shall be renovated in accordance with the methods in Practice A unless directed by the purchaser to leave the uncoated areas untreated for subsequent renovation by the purchaser.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. 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. This shall be achieved by an in-plant inspection program designed to maintain the coating thickness,?
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. In the case of orders in SI units, the values in Table 1, shall be applicable as metric units in micrometres.

The result list consists of over ASTM metal standards. 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. NOTE 8—Depending upon product design astk material thickness, or both,? 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. Coated steels Standard Number.
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 sstm below. The sample consists of one or more test articles.
This new sample shall be measured using magnetic thickness gages which have been calibrated for accuracy against reference material thickness ashm.
Marks in the zinc coating caused by tongs or other items used 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. Thanks to Total Materia we have issued real “international” specs for purchase of steels in foreign countries.
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.
NOTE 2—The presence in steels and weld metal, in certain percentages, of some elements such as silicon, carbon, and phosphorus tends to accelerate the growth xstm the zinc-iron alloy layer so that the coating may have a matte? In the case of any such local section containing more than one material adtm or steel thickness range as delineated in Table 1, that section will contain more than one specimen see Fig.

Release DataPLUS, a new module providing corrosion data, material joining information, material dimensions aa386 tolerances and coatings information helps drive even more accurate material selections! ASTM specifications represent a consensus among producers, specifiers, fabricators, and users of steel mill products. For thickness testing purposes, the entire surface area of each unit of product constitutes a specimen.

If a zinc alloy is used as the primary feed to the galvanizing bath, then the base material used to make that alloy shall conform to Speci? Inspection, Rejection, and Retest 9.
Total Materia has allowed us to solve in a definite way all problems we had for the search of alternate materials in foreign countries.
However, by agreement the purchaser is not prohibited from making tests which govern the acceptance or zstm of the materials in his own laboratory or elsewhere.
