TS 1305

TS 1305 is a terminology standard for the designation and definition of dimensions used for motor vehicles and their trailers. Its value lies in making sure that the same dimensional terms are understood consistently across design, documentation, comparison and technical communication.

Why the dimensional terms are separated

In road-vehicle engineering, terms such as overall length, width, height, wheelbase, overhang and related measurements may look similar but describe different geometric features. For trailers, the way the vehicle is coupled and how the complete vehicle combination is described can also matter. A terminology standard like this one helps prevent confusion by fixing the meaning of the names used for these dimensions.

According to the supplied scope, this standard covers the designations and definitions of dimensions for motor vehicles and their trailers. Because it is equivalent to ISO/R 612:1967, its role is primarily to harmonise terminology rather than to prescribe test methods or numerical limits.

In general technical practice, such vocabulary standards support vehicle engineering, agricultural machinery, transport equipment, approval documents and procurement specifications. They create a shared language so manufacturers, users and reviewers interpret the same dimensional concepts in the same way.

• Focuses on the names and definitions of vehicle and trailer dimensions.
• Supports unambiguous technical communication about vehicle size.
• It is a terminology standard; the supplied scope does not indicate measurement limits or test procedures.
• Linked by equivalence to ISO/R 612:1967.
