TS 9672

TS 9672 is a service standard for competent workshops that perform vehicle front geometry adjustment and wheel balancing. Its focus is not the repair procedure itself, but the organisational, physical, technical, and personnel conditions expected of the service provider.

The standard covers rules related to management, physical characteristics, technical equipment, and personnel of competent services. In practical terms, this means the workshop is evaluated as a whole: how it is run, how the work area is arranged, what equipment is available, and whether the staff are suitably qualified for the service offered.

Technical background to alignment and balancing services

Front geometry adjustment concerns the angular relationship of the wheels to the road and to the vehicle’s suspension and steering systems. Correct geometry supports stable handling, predictable steering response, and more even tyre wear. Wheel balancing addresses mass imbalance in rotating assemblies and helps reduce vibration. The two services are related but distinct: one is about alignment, the other about rotational balance.

What service suitability typically depends on

• Management organisation and service workflow
• Physical conditions and layout of the workshop
• Technical equipment needed for measurement and adjustment
• Qualification of personnel and technical responsibility
• A classification approach for identifying this type of competent service
