Recently the ISO 17025 accreditation of NMi was extended with the OIML R 46, which is good news for manufacturers of electricity meters. This means that NMi can not only test electricity meters in accordance with the IEC 62052 / 62053 series, the EN 50470 documents but also with the OIML R 46.
The OIML R 46 was published last year and will primarily be important in order to obtain metrological approvals in countries such as Australia, South-America, China and other Asian countries. Up till now NMi is the only OIML Issuing Authority that is allowed to issue OIML Certificates of Conformity for the R 46. Please see http://www.oiml.org/en/files/issuing-authorities. The document itself can be downloaded on the OIML website.
At this point both MIRS from Slovenia and NMi are preparing the cross reference of the OIML R 46 with the MID. This means that in the near future the R 46 can also be used as a normative document to issue EC type examination Certificates under the MID in Europe.
