Overview
ISO 7287:2002 - Graphical symbols for thermal cutting equipment specifies a set of graphical symbols intended for placement on thermal cutting equipment (for example, indicators and operator controls) to inform and instruct users about the equipment’s use and operation. Published by ISO/TC 44 (Welding and allied processes), Subcommittee SC 8, this second edition (2002) supersedes the 1992 edition and provides guidance to ensure symbol clarity and consistent presentation across international equipment and control panels.
Key topics and requirements
- Scope and purpose: Symbols are intended to be placed on thermal cutting equipment to convey operational and safety-related information independently of language.
- Uniform presentation: The standard references principles for consistent symbol design and publication (see ISO 3461-1 for presentation rules).
- Position-dependent meanings: Special care is required for symbols whose meaning depends on orientation or position - users should apply guidance (see ISO 81714-1) to avoid misinterpretation.
- Operator controls and indicators: The symbol set targets control-panel elements, including push-buttons, switches and status indicators used on cutting machinery.
- Examples and application guidance: Annex A (informative) includes example uses of symbols on operating boards for oxygen cutting machines, illustrating placement and context on control systems.
- Reproduction and use: The document notes permitted reproduction of terms/definitions for educational or implementation purposes under specified conditions; other reproduction requires ISO permission.
Practical applications
ISO 7287 is directly useful for:
- Equipment manufacturers designing control panels, user interfaces and machine labelling for thermal cutting equipment (e.g., oxy-fuel, plasma or other thermal cutting systems).
- Control-system and HMI designers who need standard, language-independent symbols for buttons, indicators and displays.
- Safety and maintenance personnel who rely on consistent symbols to follow operational and emergency procedures.
- Technical authors and trainers preparing manuals, instruction booklets and operator training materials.
- Regulatory and procurement teams specifying conformity and interoperability of equipment across international markets.
Benefits include improved operator understanding, reduced risk of misoperation, and more consistent international equipment labelling.
