TS ISO 6405-2

TS ISO 6405-2 addresses the symbols used on operator controls and other displays for specific earth-moving machines, equipment, and accessories. Its purpose is to support clear, rapid recognition of control functions and to promote more consistent visual language across relevant machine types.

Why machine-specific symbols matter

In general technical use, operator symbols show what a lever, button, display, or panel marking represents—such as a movement, setting, or function. On earth-moving machinery, this shared visual language helps operators interpret controls quickly and improves legibility at the point of use. ISO 6405-2 focuses on the special cases within that family: symbols intended for specific machines, equipment, and accessories rather than the common symbols used across multiple machine types.

Relationship to ISO 6405-1 and related symbol standards

The standard applies to symbols for earth-moving machinery as defined in ISO 6165. It also notes that ISO 6405-1 covers symbols common to more than one type of earth-moving machine, while ISO 7000 and IEC 60417 may be consulted for additional internationally standardized symbols that could be relevant. This distinction matters because common symbols help preserve consistency across equipment, whereas machine-specific symbols communicate the function of particular attachments or configurations more precisely.

• Markings used on operator controls
• Graphical symbols for other displays
• Special function symbols for equipment and accessories
• Use within the machine family defined in ISO 6165
