This standard provides guidance to manufacturers of contact wire for placing identification markings that identify the contact wire alloys with various conductivities. This will aid users of the wire to properly identify the type and conductivity in use on the line and on reels for proper application into the OCS. The identification of an agency's ownership on the contact wire will help in the deterrence of theft and aid in recovery by law enforcement personnel. This standard considers maintenance applications by operating agencies.This standard defines the general parameters for marking contact wires in overhead contact systems (OCS) used for electric railway and transit systems. This standard allows for the identification of various types of contact wires in composition and conductivity as well as identification of the operating agency using the wire. This standard is intended to provide a method of determining the type of contact wire as regards its chemical makeup and electrical conductivity and is not meant to replace any other marking or identification system for contact wire presently in use. Instead, it presents an alternative method of contact wire identification that is concise and easy to interpret.
