Accredited Persons (measurement)
The role of an Accredited Person (AP). What they can do.
Accredited Persons (APs) can verify and certify weights, measures, or weighing and measuring equipment. An AP's mark of verification consists of the letters AP with an identification number beside it. An AP can issue a certificate of accuracy on request.
Who can be an Accredited Person?
Only accredited companies/individuals (and Inspectors of Weights and Measures) have the power to stamp and issue certificates of accuracy for equipment. To be accredited, they must provide evidence that they have a quality management system in place that meets all the requirements of the Weights and Measures legislation.
Where an AP declines to stamp or issue a certificate of accuracy for a weight, measure, weighing or measuring instrument, they must:
- supply the user with a non-compliance notice. This must state the time, place, description of the equipment and nature of the non-compliance
- supply the Measurement and Product Safety Service with a copy of the non-compliance notice.
The user may request that another AP test the instrument for a second opinion.
An AP does not have the authority to enter premises without the user's permission or to seize equipment.
