TS ISO 9247:1990/Amd 1:1998

TS ISO 9247:1990/Amd 1:1998 is Amendment 1 to ISO 9247, dealing with the principles for identifying and marking electrical wires and cables used in earth-moving machinery. In practical terms, it concerns the coding and marking approach used to make wire runs, harnesses, and circuit conductors easier to recognize within the electrical systems of the machine.

Why wire identification matters

GENERAL TECHNICAL CONTEXT: Clear identification of wires and cables is essential in electrical design, assembly, maintenance, and troubleshooting. In mobile industrial equipment, conductors may be exposed to vibration, contamination, temperature variation, and restricted access, so a consistent identification scheme helps reduce wiring errors and improves traceability. Marking also supports faster service work by making it easier to distinguish one circuit from another and to follow cable routes across the machine.

Use in earth-moving machinery

The subject of this standard is the electrical circuitry of construction and earth-moving machines. Such equipment may combine power supply lines, control circuits, sensor connections, and auxiliary functions on the same platform. Identification codes and marking are therefore useful for separating conductor groups and keeping the system legible during manufacture and maintenance. Because this listing is an amendment, it should be understood as updating the parent standard rather than standing alone as a complete requirements document.

• Addresses principles for identifying electrical wires and cables used in machine electrical circuits.
• Applies in the context of earth-moving and construction machinery.
• Links an identification code system with physical marking practices.
• Identified as Amendment 1, so it updates the parent standard.
