Marking of Electrical Insulating Materials
|Publication Date:||1 May 2004|
This specification establishes the performance requirements for the identification of wire and cable by indirect markings that have been applied to electrical insulating materials including heat shrink sleeving, wrap around labels and "tie-on" tags as well as any other types of materials used for indirect marking. This specification covers the processes used to mark these materials, including impact ink marking, thermal transfer, hot stamp, and lasers, etc. This specification does not cover the direct marking on insulated electrical wires and cables.

Various printing processes can be used to permanently mark the surface of most types of insulation materials (flexible, rigid, braided, heat-shrinkable). The markings usually consist of circuit identification codes such as those specified in AS50881. Identification of each connecting wire as to its function or diagram location facilitates manufacture of electrical equipment and subsequent repair and maintenance. Materials that cannot be marked directly, such as unjacketed shielded wire, thermocouple wire, multi-conductor cable, and fiberglass are identified by the use of a marked insulating sleeve.
CAUTION: Metallic markers or bands should not be installed on electrical wiring.View Less
