AUstrALIAn stAndArd PIPe MArKInG GUIde

Australian Standard 1345-1995 identifies the contents, direction of flow and safety parameters for pipes, conduits and ducts through colour coding. Pipe
contents can include water, fluids, air, gasses, electronics and communications wiring. It is not intended to apply to buried or normally inaccessible services.
However, the general principles may be applied when considering those services.
