Measurement Instruments
The National Measurement Institute of Australia - NMI, affiliated to the Australian Department of Industry, Science, Energy and Resources, is the Australian Government’s national authority on measurement. NMI plays an important role in the Australian economy by maintaining and regulating Australia’s measurement system, developing and maintaining national measurement standards, and delivering world-class measurement products and client services. Headquartered in New South Wales, there are laboratories and offices throughout the country.

Unless a class of instrument has been specifically exempted, the national legislation requires that every measuring instrument that is in use for trade be of a pattern approved by the Chief Metrologist. A certificate of approval is issued for each instrument pattern after it has satisfactorily completed its approval testing and assessment. It is an offence for an instrument which is not of an approved pattern (or specifically exempted from this requirement), to be used for trade purposes. The NMI can provide information on whether the instrument comes under the definition of in use for trade. The NMI has also established a nationwide network of trade measurement inspectors to supervise traders and service license holders.


Pattern Approval is where an impartial body examines the design of an instrument prototype against national or international standards. This determines the measurement accuracy of the instrument and whether the instrument retains this accuracy under a range of environmental and operating conditions. If the instrument passes the pattern approval process, NMI will issue a certificate of approval.

ATIC certification experts maintain close contact with NMI and have conducted systematic research on NMI standards. ATIC provides testing and certification services according to NMI standards for manufactures who is intended to commercialize their measurement instruments into Australian market.
