Pattern approval requirements
Main content area
Publication Date:
March 2016
During the pattern approval process, we examine the design of an instrument.
To comply, the instrument pattern must meet its related mandatory requirements.
These requirements are either:
- prefixed with ‘NMI R’ and based on an International Organization of Legal Metrology (OIML) recommendation of the same name and number
- prefixed with ‘NMI M’ and have been prepared by the National Measurement Institute (NMI)
