22、ass 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 bare wire. Scrape thecoating from one side of the wire
23、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 coating at right anglesto the first determination.10.5 Ta
