TS EN 12526

TS EN 12526 is a vocabulary standard for castors and wheels, bringing together the relevant terms, definitions, multilingual equivalents and recommended symbols. Standards of this type help engineers, purchasers and technical writers use the same language for the same component across drawings, catalogues and product documentation, especially where closely related terms such as wheel, castor and swivel assembly can otherwise be confused.

How the terminology is organised

The standard’s focus is on naming and identifying the main elements of castor and wheel technology. In general technical usage, a wheel is the rolling element that carries load by moving over a surface, while a castor combines that wheel with a mounting arrangement that allows directional change. Vocabulary standards are valuable because they reduce ambiguity in design, procurement, maintenance and multilingual communication, where precise wording matters as much as the component itself.

Why recommended symbols matter

• Provides a common technical vocabulary for castors and wheels.
• Supports consistent translation and catalogue preparation in multiple languages.
• Uses recommended symbols to make technical drawings and documentation shorter and clearer.
• Helps align terminology across furniture, mechanical systems and enclosure-related applications.

As a vocabulary document, this standard is about terminology and graphical representation rather than performance requirements or test methods. Its practical value lies in making sure the same part is described consistently, which improves communication between designers, manufacturers and users.
