Weights and Measures
Trade Equipment Verification
Most types of weighing and measuring equipment used in transactions are legally required to be verified before they are used. This ensures that the equipment gives a fair and accurate result.
Verification involves checking the equipment for accuracy and making sure that it meets any design and installation requirements that may have been imposed on it. Equipment is first verified before it is initially put into use – sometimes during the manufacturing stage – and again after repairs or alterations have been made to it after any malfunction.
This process is sometimes known as ‘stamping’, as the traditional method of showing the equipment complied with the law was for a Weights and Measures Inspector to apply a Crown stamp to the item.
Our Weights and Measures Inspectors can carry out initial verification of a range of equipment, ranging from petrol pumps and shop scales to weighing equipment installations in factories. They can also re-verify all types of equipment after adjustment or repairs have been made.
Disqualification of Equipment
Our Inspectors also carry out unannounced inspections of equipment in use for trade. These inspections include businesses such as pubs, shops, petrol stations and factories. They have the power to disqualify any equipment that they find to be inaccurate or being improperly used.
They may apply a Crown sticker showing the Crown crossed through with a six pointed star, or they may obliterate any Crown stamped seals on the item with a six pointed star. It then becomes illegal to use the equipment again until it has been repaired and re-verified.

- If it is a petrol pump, how many nozzles require testing
- Address where the equipment is located
- Whether the equipment is new or needs re-verifying after disqualification or repair
