NOTE: To prevent contamination during final polishing, never allow test coupon to come into contact with bare fingers or water. 8 Polish first the ends and then the sides with 150-mesh silicon carbide grains picked up with a pad of absorbent cotton moistened with isooctane. 9Polish strip uniformly using long strokes that carry beyond the end of the copper strip. 10Remove any metal dust with clean cotton pads moistened with isooctane. 11When strip is clean, with minimal delay, slide copper strip into sample tube and re-stopper.
