    Revision of B193 - 16 Standard Test Method for Resistivity of Electrical Conductor Materials

    (What is a Work Item?)

    Active Standard: B193 - 19

    Developed by Subcommittee: B01.02 | Committee B01 | Contact Staff Manager



    conductivity; electrical conductor materials; resistivity; resistivity of electrical conductor; volume resistivity; weight resistivity;;


    An error was made to Table 2 when the Temperature Coefficient of Resistance at 20C was added to the chart. The correct value is 0.00320 and not 0.00360 that is shown. In 2015 the coefficient value was added to the B193 standard. The value was pulled from Table 3-6 of the Aluminum Associations Aluminum Electrical Conductor Handbook, 3rd Edition, published in 1989. It has recently been identified the value inserted corresponds for aluminum clad steel and not for the intended zinc coated steel material. The corrected value needs to be inserted.
