Weights and Measures (Northern Ireland) Order 1981*
* From 26 May 2008 see Consumer Protection from Unfair Trading Regulations.
This Order controls the trade use of weighing and measuring equipment and sets out how goods should be sold by weight or measure. It states that some goods should only be packed and sold in specific quantities and it makes it a criminal offence to sell short weight or measure.
In order to ensure consumers get what they pay for, Trading Standards Inspectors regularly test weighing and measuring equipment for accuracy and check packs of foodstuffs and other goods to make sure they contain the correct quantity.
