ASTM WK42339

    Revision of A416 / A416M - 12a Standard Specification for Steel Strand, Uncoated Seven-Wire for Prestressed Concrete

    (What is a Work Item?)

    Active Standard: A416 / A416M - 12a

    Developed by Subcommittee: A01.05 | Committee A01 | Contact Staff Manager


    1. Rationale

    Removing Normal Relaxation from A416. Normal Relaxation strand is no longer manufactured in this country. The material supplied when normal relaxation is ordered may be Low Relaxation strand or may have relaxation properties that are between Normal and Low relaxation. Removing Normal Relaxation from the specification will help engineers and designers have a better understanding of the properties of materials utilized when Low Relaxation is not specified. All other relaxation types would require documentation of the properties of the material supplied.
