Manufacturers can draw on our specialised conformity assessment services to enable them to place regulated weighing and measuring instruments on the market. These include items as diverse as beer glasses, fuel dispensers, precision balances, railway weighbridges, supermarket scales, taximeters and water meters.
The Measuring Instruments Regulations 2016 (as amended) and the Non-automatic Weighing Instruments (
NAWI) Regulations 2016 (as amended) supply the legal framework for conformity assessment within the
UK.
Outside the
UK, recommendations for specific weighing and measuring instruments are produced by the International Organisation for Legal Metrology (
OIML).
