Importance of legal metrology

Legal metrology is an essential requirement, which underpins the sale at both retail and wholesale level of food, petrol and many other goods.

Legal weights and measures are fundamental to a sustainable trading economy. The concept of sale and purchase cannot exist without them. In our everyday lives people make many purchases that rely on their confidence in the system that ensures correct measurements, and likewise businesses need to know they are trading in a fair marketplace where no one company has an unfair competitive advantage.

In the UK, a legislative and practical enforcement programmer is in place to ensure this. All new weighing and measuring equipment at the design stage has to be type approved by National Measurement Office to examine and test that it is fit for use. Before it is used, it is verified to ensure its accuracy by a notified body, approved by National Measurement Office. While it is in use the trader will be responsible for its ongoing maintenance and accuracy and correct use.

To ensure that consumers and businesses alike have confidence in the system of Legal Weights and Measures in the UK, National Measurement Office works closely with Local Authority Trading Standards Services and collaborates with manufacturers and suppliers. To ensure that legal weights and measures are practiced consistently throughout Europe and the world, National Measurement Office also plays an active part in coordinating with WELMEC, the European cooperation in legal metrology and the International Organization of Legal Metrology.
