These pattern approval requirements are mandatory. Those with an NMI R prefix are based on an OIML international recommendation of the same name and number, whilst those with an NMI M prefix have been prepared by NMI. See General Certificates for requirements for instruments that are capable of being manufactured to a common standard, e.g. simple measures.
When printing, make sure you print the comments too. We have supplied recommended print versions (where comments are summarised on each page) for NMI R 60, NMI R 76-1 and NMI R 117.
