UL线缆印字在UL758和C22.2 No 210中有要求，具体可参考以下，希望有帮助!

下面是参考的UL758印字要求

location, an additional distinctive marking shall be provided that identifies the specific
manufacturing location of the AWM.
Other markings such as wire size, number of conductors, and similar data, are determined to be in
compliance with this requirement when they are not confusing or misleading.
50.3 For a cable that contains a conductive polymeric shield, the jacket or marker tape shall be marked
²Conductive Shield,² ²Contains Polymeric Conductive Shield,² or equivalent and the marking shall be
repeated at the following intervals throughout the entire length of the cable:
a) Markings on the outer surface of the cable shall be repeated at intervals that are not longer
