JIS C 3327 Cable Code Designation
JIS C 3327 designation system is elegant in its logic. Every cable name follows a predictable, parseable structure where each character or character group carries a specific, unambiguous meaning. Once you understand the five material symbols and the four flexibility classes, you can decode any of the 15 cable types defined by the standard—and immediately know what the cable is made of, how flexible it is, and what applications it is suited for.
