On-Board Mass (OBM) Systems

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.

TCA grants approval for OBM systems against the On-Board Mass System Functional and Technical Specification.

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

How it can be used

The On-Board Mass System Functional and Technical Specification may be used for the following broad purposes:

  • For service providers assessing current OBM system offered to transport operators
  • For service providers of OBM systems applying for type-approval (or equivalent approval mechanism)
  • For transport operators assessing current OBM systems (already fitted to vehicles)
  • For transport operators comparing different OBM systems (when procuring new OBM systems)
    Note: TCA cannot and does not make any representation that OBM systems that have not been approved by TCA satisfy the requirements of the specification. It is solely the responsibility of the user to satisfy themselves whether a non-TCA approved OBM system meets the specification and that the service provider is a legitimate business with sufficient financial standing.
  • For transport operators entering into business arrangements with providers of OBM systems (by demanding that OBM systems satisfy the requirements of the specification when preparing tenders and contracts).

Alternatively, transport operators can purchase OBM systems that have been type-approved by TCA.

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