Scales used by merchants, including butcher scales and scales accessible to customers in supermarkets, must undergo periodic inspections. Scales must meet regulatory standards, ensuring accurate and traceable weighing operations. If the scale is uninspected, the inspection mark is out of date, or the seal is broken, it should not be used.

The Metrology Department of the FPS Economy conducts inspections of scales in businesses to ensure they comply with legal requirements. This ensures that consumers can trust the accuracy of these measuring instruments.
