Weighs of different sizes

Norfolk Calibration Services is open for business as usual throughout this pandemic, as we're an essential service providing support to the public and private sectors.

Weights and measures legislation controls all weighing or measuring equipment in use for trade purposes.

Trade purposes refers to when you buy and sell using the equipment.

Most of the equipment must be of an approved form. It must also be 'passed as fit for use for trade' by:

  • An Inspector of Weights and Measures
  • A notified body
  • The manufacturer or their authorised representative
  • An installer or repairer

Equipment must be suitable for its intended purpose and sufficiently accurate. There are two different types of verification, commonly referred to as EC and UK:

  • EC verification is for instruments that have a Type Approval Certificate or Type Examination Certificate. An EU member state will issue these for use anywhere within the EU.
  • UK verification is for equipment that in most cases has a Section 12 Notice of Approval. The National Measurement Office issue these for use within the UK.

The UK's departure from the European Union

We've already prepared for the UK's exit from the European Union and we'll continue to service your needs.

We're becoming a UK Approved Body. We'll be able to verify instruments within the classifications below that bear the UKCLA marks. We'll also provide re-qualifications on instruments as normal.
