ASTM B22 Standard Specification for Bronze Castings for Bridges and Turntables

ASTM B22 describes the criteria for bronze castings for turntables, moveable bridges, and bridge parts used for the construction of bridges, and bronze castings appropriate for fixed and expansion bearings in bridges and other structures with slow, intermittent motion are outlined in this specification. The UNS Nos. C86300, C90500, C91100, C91300, and C93700 Copper Alloys are listed in ASTM B22.

    Introduction to ASTM B22

    Turntables, moveable bridges, and bridge parts used in the construction of bridges are all covered by ASTM B22, which also specifies the requirements for bronze castings suitable for expansion and fixed bearings in bridges and other structures with slow, intermittent motion. The castings must meet the specified elements’ compositional requirements. The existence of additional items is not prohibited by these specification limitations. For unidentified elements, limits might be set and analysis would be necessary. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM B22 tests for our clients. 

    ASTM B22 Test Method

    Compression TestThe force that results in a permanent set of 0.001 in. (0.025 mm) in the compression test specimen is the deformation limit in compression. For Copper Alloy UNS Nos. C91100 and C91300 castings, one compression test, and one tension test are performed for each copper alloy.
    Brinell Hardness TestThis test is performed with a load of 3000 kg, which is applied for half a minute to the finished surface of the copper specimen.

    ASTM B22 Test Specimens

    Specimen DetailCopper alloys are used as specimens in ASTM B22
    Specimen SizeThe specimens are cylinders that have a cross-sectional area of 1 square inch and their height should be 1 inch.

    ASTM B22 Test Result

    To sum up, this standard specification lays out specified specifications for bronze castings that are utilized in turntables and bridges. It guarantees the quality and appropriateness of bronze castings for structural applications in the construction of bridges and turntables by specifying precise requirements for composition, dimensions, and mechanical qualities.

    ASTM B22 Related Tests

    ASTM B22 is related to tests, including ASTM B208 for preparing test specimens for tension testing of castings, ASTM B824 for castings based on copper alloys, and ASTM E527 for alloy and metal numbering.
