ASTM F2329

It is important to note the acceptance criterion in all cases is zero defects. It is intended to be applicable to fasteners that are centrifuged or otherwise handled to remove excess zinc. ASTM does not give any warranty express asm implied or make any representation that the contents of this abstract are accurate, complete or up to date. C Coating thickness frequency of measurements: The packaging shall comply with the purchaser requirements.

The standard specification that covers the requirements for hot-dip zinc coating applied to carbon steel and alloy steel bolts, screws, washers, nuts, and special threaded fasteners applied by the hot-dip coating process. Nails v2329 rivets are not included in this speci?

Electroplating is an entirely different process and is a much thinner coating. A covers galvanizing on many products including fasteners, while F is specific to threaded fasteners, nuts and washers. Also in which material we are coating or galavanizing. Thank you for the useful content. Furthermore, there are two types of f229 lots: The two specifications have virtually identical coating thickness requirements.

A touches on threaded fasteners, but is not fastener specific. Phil- The hot dip galvanizing process is more or asgm the same within all of those standards, the difference is how they are handled. 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. Astmm 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.

According to F Paragraph 5. If the customer specifies, the galvanizer will be required to provide the average f232 temperature the fasteners will be exposed to. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

There are three columns listing the number of test articles for three different inspection tests required under F Will galvanizing bolts, that will be used for Sub-Sea hydratightightening using AquaMax jacks permissible, or would the stretching of the bolt under tension remove the galvanized warranty.

According to Note C of Table 1, It is only required to conduct testing on samples for coating thickness once every five batch lots. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The average of those selected measurements is the average coating thickness.

The dull appearance shall not be cause for rejection. Vinay- ASTM A and A both say that the maximum service temperature for galvanized bolts should not exceed F unless caution is used in regard to the potential for liquid hydrogen embirittlement. For each of these types, there are also inspection criteria for coating thickness, visual appearance, and adhesion.

In the case of a fully threaded rod, the thickness measurements shall be determined at each end of the article. Also, A and F have different sampling requirements; F requires more samples per lot than A Average Thickness of Individual Specimen qstm.

Any insights f229 be deeply appreciated.

The material provided herein has been developed to provide accurate and astn information about after-fabrication hot-dip galvanized steel. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

All the ASTM fastener standards refer to F for hot dip galvanizing, so that would be the most appropriate standard to reference. Also a high tension rod U Bolt 14mm diameter and 2 meters in length also with its respective fasteners. For high strength fasteners having a speci?
