Pattern Approval Requirements

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.
