Weighbridges

If you're using a weighbridge for trade, it must be a type approved by Trading Standards.

Approved types of weighbridges

You must use a weighbridge of a type approved by Trading Standards when it's used for trade.

See What equipment your business can use for more information.

Search the approval certificate register to find approved types.

Your weighbridge must also have the mark of verification stamped upon it. This is a crown or the letters 'AP' followed by a number. It's issued by an Accredited Person or a Trading Standards Officer.

Location and condition of weighbridges

Every weighbridge should be designed so that the operator, when positioned by the primary indicator, has a clear view of the load receptor.

Weighbridge:

  • deckplates must be bolted down and clear of the surrounds
  • pits must be regularly cleared of accumulated debris such as spillage of fertiliser.

Road weighbridges, and road or rail weighbridges, must not be used for trade unless they meet all these conditions:

  • approaches are smooth, straight, and on the same level as the load receptor
  • approaches have a run-on and run-off constructed of concrete or other suitable material
  • there is adequate drainage, and the bridge is kept free of mud and other debris.

Weighbridge ticket requirements

If goods are delivered loose in bulk by weight or measure, the seller of the goods must send or deliver to the purchaser a delivery note, invoice or weighbridge ticket stating the net weight of the goods delivered.

The delivery note, invoice or weighbridge ticket should also show the:

  • date — for example 20 October 2010, or 20/10/10
  • name and address of seller
  • name and address of purchaser
  • cost.

Testing requirements

We recommend you have your weighbridge tested annually and issued with a Certificate of Accuracy. This can be done by an Accredited Person.

Penalties for breaching the Weights and Measures Act

Under the Weights and Measures Act, it's an offence to use a false or unjust weight or measure (including a weighbridge), or a weight or measure that is not approved as required under the Act. It's also an offence under the Act to deliver a lesser quantity of goods than purchased where goods were sold by weight, measure, or number.

Depending on the offence, you could be issued with an infringement notice and required to pay a fine of up to $500. Alternatively, you could be charged in the District Court with breaches of the Act. Depending on the offence breached, you could be subject to a higher penalty.
