Proposal, 13 October 2005
A key comparison BIPM.L-K11 is ongoing to achieve traceability for primary wavelength standards at wavelengths in the list of recommended radiations that are used in dimensional metrology. In order to claim traceability in compliance with the MRA and related ISO/IEC 17025, comparisons of primary standards are needed when realizing the definition of the SI-metre according to the method (c) in the Mise en Pratique (MeP) and a traceable link to the SI-second using calibrated instruments and validated measurement techniques in the case of method (b). In the K11, in addition to measurements carried out at the BIPM, absolute frequency determinations are expected to be made in regional comparisons, also.
MIKES offers to act as a regional host in northern Europe for the BIPM ongoing key comparison on primary wavelength standards (BIPM.L-K11). MIKES provides absolute frequency measurements of lasers stabilized to iodine according to the international recommendations at wavelengths
