Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

This specification covers the requirements for hot-dip galvanizing on iron and steel products made from rolled pressed and forged shapes, f239, plates, bars, and strips.

Afif — The difference between hot dip galvanizing structural articles and fasteners is the spinning. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement satm such rights, are entirely their own responsibility. This abstract is a brief summary of the referenced standard.

ASTM F – Portland Bolt

A touches on threaded fasteners, but is not fastener specific. ASTM does not give any warranty express or implied or make any representation that the aetm of this abstract are accurate, complete or up to date.

Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. To determine how many samples are required to test for conformance based on the lot size, F refers to Table 3 of F, Practice for Fastener Sampling for Specified Mechanical Ast and Performance Inspection.

ASTM F2329 vs. ASTM A153

If required by the product standard or by the purchaser, mechanical zstm with or without? In addition, small parts shall be air cooled as needed in order to prevent the formation of zinc oxide. Minor roughness that does not impair the intended use of the part, or roughness that is related to the uncoated surface condition of the part, shall not constitute grounds for rejection of the parts.

Combining values from the two systems may result in non-conformance with the standard. For high strength fasteners having a speci? One of our experienced sales reps will be happy to answer any of your questions.

Therefore, it must be clarified whether the plant has the ability to lubricate hardware after hot-dip galvanizing. Current edition approved Feb. Sal- Are you asking which galvanizing standard you should be using?

ASTM F vs. ASTM A | American Galvanizer’s Association

ASTM A This specification covers the requirements for hot-dip galvanizing on iron and steel products made from rolled pressed and forged shapes, castings, plates, bars, and strips.

If your requirement is for hot dip galvanizing, electroplating would not be sufficient. C Coating thickness frequency of measurements: The number of specimens to be tested per order shall be as speci? Also, A and F have different sampling requirements; F requires more samples per lot than A Table 2 of F lists average coating thickness requirements for production lots, batch lots, and individual specimens.

The purchaser shall ensure that the effect of the heat generated by the galvanizing process astj compatible with the fastener regarding the?

The coating thickness requirements of A Table 1 meet or exceed those of F Table 2 except for: NOTE 1—The scope of this speci? If certified test reports are not available, then the supplier must default to Sample Size C and conduct the tests required.

The average of those selected measurements is the average coating thickness. F — 05 Standard Speci? The selection of the sampling plan shall be in accordance with Guide F Link to Active This link will always route to the current Active version of the standard.

Portland Bolt performs hot dip galvanizing of threaded fasteners within our 85, square foot manufacturing facility. Coating Thickness Table 2 of F lists average coating thickness requirements for production lots, batch lots, and individual specimens. F defines the two different lots and their associated sampling asmt as follows: Adhesion testing is not typically performed when galvanizing to the requirements of A unless there is evidence of an adhesion concern, but F requires adhesion testing stout knife test to be performed for the number of articles listed in Table 1, and for every batch lot.

The major differences between the two specifications, described below, include topics related to sampling protocol, coating thickness, inspection, embrittlement, and documentation. The temperatures used in the hot-dip galvanizing process typically do not appreciably alter the mechanical properties of steel, but there are some instances when there are potential concerns. Therefore, the supplier of the fasteners submitting the product to the galvanizer shall be aware asym the tempering temperature of the fasteners relative to the temperature of the adtm bath and the potential effect it may have on the product.

For long pieces anchor rods asm articles greater than five feet in lengthcoating thickness measurements must be taken on each end and in the middle of the article. Thank you for the useful content.

In no case shall the average of the measurements be below the average thickness shown in the Average Thickness on Individual Specimen column see Dane- Thanks for response. Average Thickness of Individual Specimen 0. The manufacturer shall afford the representative of the purchaser all reasonable facilities to satisfy him that the zinc coating is being furnished in accordance with this speci?

It is important to ensure the customer asgm which type adtm lot is required. ASTM F describes two different sampling plans for batch lots and production lots.
