8、n 0.014 mm Overall diameter, max 0.746 mm Test Method: Discard approximately 3.5 m of wire from the spool. Measure the diameter of the coated wire on the spool at 2 points 1.2 m apart. Remove the coating by suitable means not injurious to the bare wire at approximately the same position on the wire

9、and repeat the measurements around the bare wire. In each set of measurements, the diameter shall be measured at 4 points on the circumference approximately 45 degrees apart. The difference between the average diameter of the coated wire and the average diameter of the bare wire shall be considered

10、addition due to the coating.
