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. This shall be achieved by an in-plant inspection program designed to maintain the coating thickness,? The average of no less than? For more information on the ASTM designation system see our related 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.

The galvanizer has only limited control over this condition. Lumps, projections, qstm, or heavy deposits of zinc which will interfere with the intended use of the material will not be permitted.

The result list consists of over ASTM metal standards. For magnetic thickness measurements, specimen excludes any area of the surface which is subject to processes such as?

Sstm 5—Inaccessible surface areas are those which cannot be reached for appropriate surface preparation and application of repair materials as described in Practice A For test by the purchaser after delivery, the lot consists of the single order or the single delivery load, whichever is the smaller, unless the lot identity, established in accordance with the above, is maintained and clearly indicated in the shipment by the galvanizer. The pieces shall be handled so that after galvanizing they will not freeze together on cooling.

In the case of orders in SI units, such shall be stated to the galvanizer when the adtm is placed.

The other values are based on conversions using the following formulas: The average of the? NOTE 8—Depending upon product design or material thickness, or both,?

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. 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.

NOTE 6—The requirements for the? The sample consists of one or more test articles. Do not use testing carried out at edges or corners points of lowest coating adhesion to determine adhesion of the coating. 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 of the zinc-iron alloy layer so that the coating may have a matte? Where products consisting of various material thicknesses or categories are galvanized, the wstm thickness grades for each thickness range and material category of material shall be as shown in Table 1.

This article contains a list of standards that covers among other things: Purchasers desiring a guarantee of heavier coatings than the minimum thicknesses shown herein should use the special requirements see 4.

Surface conditions related to de? ASTM specifications asym a consensus among producers, specifiers, fabricators, and users of steel mill products. Such inaccessible areas, for example, would be the internal surfaces of certain tanks, poles, pipes, tubes, and so forth.

Materials and Manufacture 5. Each system shall be used independently of the other without combining values in any way. The accuracy of both methods will be in?

ASTM A – Withdrawn Specification for Zinc Coating (Hot-Dip) on Assembled Steel Products

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The zinc coating on threaded components of articles galvanized under this speci? In the case of orders in SI units, the values in Q386 1, shall be applicable as metric units in micrometres. Thanks to Total Materia we have issued real “international” specs for purchase of steels in foreign countries.


DataPLUS, a new module providing corrosion data, material joining information, material dimensions and tolerances and coatings information helps drive even more accurate material selections! 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. For thickness testing purposes, articles whose surface area is greater than in.

Such a plan is contained in Test Astn B which addresses sampling procedures for the inspection of electrodeposited metallic coatings and related? This standard has been approved for use by agencies of the Department of Defense.

Minimum average thickness of coating for any individual specimen is one coating grade less than that required in Table 1. A specimen must be evaluated for each steel category and material thickness within the requirements for each specimen of the test article.

These a368 are raised surfaces and are easily knocked off FIG. The specifying of tests for adhesion and embrittlement shall be subject to mutual agreement between the galvanizer and purchaser.
