This specimen may be any leng
24、th ofwire over 12 in. (305 mm).10.3 For Class 1 and Class 2a material, strip the coatingmechanically from the wire and measure the minimum andmaximum thickness of the coating with a suitable micrometer.10.4 For Class 2b material, strip the coating by chemicalmeans and determine the diameter of the b
25、are wire. Scrape thecoating from one side of the wire and measure the reduceddiameter with a micrometer. The thickness of the coating at thispoint is the difference between the measurement thus obtainedand the measured diameter of the bare wire. In a similarmanner, determine the thickness of the coa
26、ting at right anglesto the first determination.10.5 Take care not to remove any of the metallic surfacewhen removing polymer coating by scraping.11.
