TS ISO 6405-1

TS ISO 6405-1 is a graphical-symbols standard for the common symbols used on operator controls and other displays in earth-moving machinery. In practical terms, it helps create a consistent visual language for machine functions, so operators can recognise controls, indicators and functional markings without relying only on text.

What the common symbols are for

Earth-moving machinery, as defined in ISO 6165, covers a broad family of equipment used for excavation, loading, hauling and related site work. Because this standard focuses on common symbols for controls and displays, its role is to support clearer communication where visual identification matters more than language-specific wording. The same symbol approach may also be applied to other self-propelled work machines when similar functional needs exist.

Technical context for machine interfaces

Graphical symbols are valuable in machine interfaces because they can convey function quickly across language barriers and reduce dependence on written labels. That matters in construction and excavation environments, where operators may work with different machine brands, in different regions, or under changing site conditions. A standard centred on common symbols aims at reusable, broadly understandable representations rather than machine-specific markings.

This listing represents a withdrawn edition of TS ISO 6405-1, so it is useful as a historical technical reference for the subject area. In symbol standards, consistency is the core value: using the same visual convention for the same function across machines can improve recognition, training and operational familiarity.
