• Functional and technical requirements for OBM systems
• Certificate of Conformance

The following is useful information about suppliers of type-approved OBM systems, the models and applications of the National Telematics Framework (NTF) they support, including features and levels of assurance.

Approval may be in the form of type-approval or an equivalent approval mechanism acceptable to TCA. Suppliers of OBM systems must meet applicable requirements in the functional and technical specification, irrespective of the approval mechanism.

OBM systems are able to measure the mass of axle groups and calculate the gross vehicle mass of a vehicle.

OBM systems are often referred to as on-board weigh scales or electronic weighing systems, and are widely used across the surface transport sector commercial, contractual and regulatory purposes.

Functional and technical requirements for OBM systems

Performance-based functional and technical requirements for OBM systems are contained in the OBM System Functional and Technical Specification.

The Specification contains three categories to cater for different uses. 

The three categories are presented in the table below:

Certificate of Conformance

A Certificate of Conformance for each TCA-approved OBM system will be made available by the OBM supplier (or associated agent, distributor or retailer) at the point of supply to transport operators of each OBM system.

The current cost to the OBM supplier for each certificate of conformance is AUD 20.
