ASTM F219

These test methods cover the testing of fine wire, flat or round, approximately 0.010 in. (0.25 mm) and smaller in diameter or thickness, used in electronic devices and lamps. Chemical analysis of the material shall be made in accordance with the requirements prescribed. The procedures in determining the out-of-roundness, edgewise curvature of ribbon, and straightness of straightened round wire are presented in details. Tension test and electrical resistivity test shall be performed to meet the requirements prescribed.
