TS ISO 6405-1/Amd 1

TS ISO 6405-1/Amd 1 is an amendment to the TS ISO 6405-1 series dealing with common graphic symbols for operator controls and other displays on earth-moving machinery. In practical terms, it belongs to the vocabulary of machine interfaces that help operators recognize controls and display indications quickly and consistently across equipment.

Why graphic symbols matter on machinery

On earth-moving machinery, symbols provide a language-independent way to identify functions on buttons, levers, screens, warning areas, and indicators. From a general technical perspective, they support faster recognition, reduce ambiguity, and help designers present the same function in a consistent visual form across different machine models. Common symbols are especially useful where operators move between machines from different manufacturers or between different machine types within the same fleet.

What this amendment means

The phrase “Amendment 1: Additional symbols” indicates that this document adds symbols to the parent standard’s symbol set. It should therefore be understood as an extension of the underlying common-symbol framework, not as a standalone base standard. For users, the main value is broader symbol coverage for newer or more specific machine functions while preserving the general logic of established operator-symbol conventions.

• Symbols are used to communicate machine functions without relying on text.
• Common symbols cover recurring functions used across multiple machine types.
• As an amendment, this document extends the parent standard rather than replacing it.
• Consistent symbol design supports usability and helps reduce misinterpretation in daily machine operation.
