This standard specifies the process to be applied for measuring the contrast of wire and cable identification
markings against the background of the unmarked wire insulation. It has been developed primarily to define a
reproducible process of contrast value determination for use both to determine the intrinsic laser markability of
wires at the time of manufacture or later, and to enable electrical wiring systems manufacturers to ensure that
the whole process of wire marking is carried out to the required standard.
