Scope

This part of GB/T 4909 specifies the measuring tools, sample preparation, measurement steps, test results, and evaluation for the size measurement of bare wires.
This part is applicable to measuring the external dimensions, roundness radius, taper ratio, and cross-sectional area of various circular, rectangular, and shaped conductors, as well as stranded conductors.
When there are higher requirements for the measurement accuracy of external dimensions, etc., the corresponding product standards shall prevail.
This part should be used in conjunction with GB/T 49091—2009.
