ASTM A123/A123M-17 Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products

ASTM A123/A123M-17 Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products

ASTM A123/A123M-17 test method determines the characteristics of fabricated and unfabricated products by determining the requirement of zinc coating. The iron and steel products undergo galvanization. The final results of this method are displayed keeping in view the international standards and inch-pound units.

    ASTM A123/A123M-17 test method covers the exposure of iron and steel to galvanization. The coating properties of various materials are determined, and their application is decided. The results aid in the research, quality check, performance evaluation, and improvement of the materials. The method is intended to ensure effective performance and durability.


    In ASTM A123/A123M-17, the dimensions of the specimen are determined and the specimen undergoes testing depending upon the pre-determined tolerance level. The tests detecting the coating thickness and magnetic thickness are performed. The microscopic study of the process is done, and the sample’s weight before and after the coating is recorded. The results are recorded, evaluated, and documented as per the globally accepted standards. 

    Specimen Size:

    Specimen size should be as per the requirements. In this case, a unit of the product whose surface area is equal to or less than 160 inches square is tested.


    The method covers the certification, sampling, testing, and inspection of the specimen within the set limits. 


    The ASTM A123/A123M-17 test method is specifically important for the quality assurance and durability of zinc coating on iron and steel bars. In this regard, the top service provider is the Infinita Lab, which ensures efficient and reliable testing.
