National Measurement Office can now issue certificates under OIML R35

The National Measurement Office can issue certificates to organisations producing material measures of length for general use (OIML R35).

The National Measurement Office (NMO) has become only the second International Organisation of Legal Metrology (OIML) issuing authority in the world to be appointed to issue OIML R35 certificates of conformity.

OIML R35 is the international recommendation for ‘material measures of length for general use’ and complements our existing services for issuing OIML R98 certificates (high-precision line measures of length) and our services as a notified body under MI-008 of the Measuring Instruments Directive (MID), 2004/22/EC, for material measures of length.
