Determinations of Recognised-value Standards of Measurement

Under the National Measurement Act, NMI is able to determine recognised-value standards of measurement. We have made the following determinations:

• accuracy of a reference standard of measurement
• acceleration due to gravity in a vacuum
• acceleration due to gravity (National Measurement Laboratory, now NMI)
• density of mercury
• density of water
• density of standard mean ocean water
• dynamic viscosity of water at a temperature of 20°C
• dynamic viscosity of water at a temperature in the range 19.98°C to 20.02°C
• velocity of electromagnetic waves in a vacuum
• positions of the Australian fiducial network locations

The above determinations are available from The Federal Register of Legislation at https://www.legislation.gov.au/

A summary of the determinations is currently being revised and will be uploaded soon.
