National Measurement Act 1960

If an article is packed in advance ready for sale, the package may be marked with an AQS mark.

AQS stands for Average Quantity System. It is an internationally recognised system for sampling and testing groups of packages to determine whether, on average, they contain the quantities with which they are marked.

By marking a package with an AQS mark, a person represents that if the package is included in a group of like packages sampled and tested in accordance with AQS procedures, the group will be found on average to contain a measurement at least equal to the marked measurement.

This Division contains offences to deal with cases where this is not so (see Subdivision 3‑C).

This Division also contains offences to deal with cases where misleading marks are used, or an AQS mark is placed in the wrong place (see Subdivision 3‑B).
