Legal Metrology Delivery: pre-assessment

Information for manufacturers.

The Office for Product Safety and Standards (OPSS) offers pre-assessment services to manufacturers through its Legal Metrology Delivery (LMD) team, covering the certification required to place regulated weighing and measuring instruments on the market.

The purpose of pre-assessment is to help you understand the requirements relating to the instrument type you wish to get certified.

OPSS is not permitted to provide consultancy since it offers product certification services to manufacturers. As a result, we cannot resolve issues or tell you what to do. However, we can give our expert insight into the requirements and clarify them in the context of your circumstances. We can also direct you to existing advice and guidance that may be of assistance.

Please note: OPSS no longer issues quality management system certificates, and only issues product certificates in specific circumstances, for instruments outside the scope of the Measuring Instruments (MI) Regulations 2016 or the Non-Automatic Weighing Instruments (NAWI) Regulations 2016 (both as amended).
