Weights and Measures

Verification Sticker

Weights and Measures is the legal term for uniform standards with regards to the quantity, capacity, volume, or dimensions of anything.

All weighing equipment in use for trade must be suitable for its intended purpose and be sufficiently accurate. Non-automatic weighing machines are either 'passed as fit for use for trade' by an inspector of weights and measures (trading standards inspector) or an 'approved qualifier'.

All the equipment used for trade purposes must bear the stamp or stickers.  Additionally, weights that are in use for trade in conjunction with weighing equipment must be stamped with the crown stamp.

How to tell if equipment is suitable for trade or commercial use

Equipment that is suitable for trade or commercial use is required to have a stamp or verification marks to show that it is suitable and accurate. Please note: kitchen weights and scales, are not suitable for and therefore cannot be used for trade or commercial purposes.

New designs of electronic scales do not have to be stamped, instead they will bear a green sticker with the letter M in black, together with the approved qualifiers identification sticker and other markings including the CE mark (CE marking indicates the compliance with EU legislation of a product).

The verification marks are more often put with the data place adjacent to the serial number and other technical information about the weighing machine. 

If an officer finds the equipment exceeds the permitted tolerances they will remove the stamp with a six pointed star if the machine is crown stamped or put a sticker with a red six pointed star on the machine.
