It also provides astn minor coating repairs. 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.

For test method, see The batch lot inspection process is more similar to inspection under A than inspection of production lots, but Table 1 of F has some additional requirements to consider.

ast It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For high strength fasteners having a speci? This method is similar to an inspection of coating thickness on multi-specimen articles galvanized per ATSM A Baking shall be conducted after asfm and prior to hot-dip galvanizing.

The method for testing the condition of adherence is speci? Thank you for the useful content.

R2329 10, Authored by Alana Hochstein. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. The following tests shall be made to ensure that the zinc coating is being furnished in accordance with this specification: For example, a lot size of articles under the detection process requires testing of 11 samples for coating thickness, 11 samples for visual appearance, and 3 samples for adhesion.

Rob- Tensioning the bolt will not adversely affect the galvanizing. 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.

Many thanks Sal from Dubai. These requirements are established by the applicable product standard, such as Speci?

ASTM F2329

The zinc used for the coating shall conform to the chemical composition required. According to F Paragraph 5. 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.

The two specifications have virtually aastm coating thickness requirements.

It is important to ensure the customer specifies which type of lot is required. In the case of a fully threaded rod, the thickness measurements shall be determined at each end of the article. Electroplating is an entirely different process and is a much thinner coating.

Also a high tension rod U Bolt 14mm diameter and 2 meters in length also with its respective fasteners. Note—Based upon mathematical calculations, 1. It is not a dip spin coating like hot dip galvanizing is. The selection of the sampling plan shall be in accordance with Guide F Beams and structural members are defined as steel products and are galvanized per A Leave a Reply Cancel reply Your email address will not be published.

The coating thickness requirements of A Table 1 meet or exceed those of F Table 2 except for:. We are are not certain what standards are c2329 used in Dubai, so we cannot speak to those. If the customer specifies, the galvanizer will be required to provide the average galvanizing temperature the fasteners will be exposed to.

Coating Thickness Table 2 of F lists average coating thickness requirements for production lots, batch lots, and individual specimens. Nails and rivets are not included in this specification. Average Thickness of Individual Specimen 0. If your requirement is for hot dip galvanizing, electroplating would not be sufficient.

Thus, the thickness determined is a point value. The coating thickness requirements of A Table 1 meet or exceed those of F C2329 2 except for: Materials and Manufacture 5.

Hot-Dip Galvanizing Specifications

Sal- Are you asking which galvanizing standard you should be using? Furthermore, there are two types of production lots: A covers galvanizing on 2f329 products including fasteners, while F is specific to threaded fasteners, nuts and washers. The dull appearance shall not be cause for rejection.
