AC/DC voltage transfer difference at low voltages - EURAMET
The results of EURAMET.EM-K11.1 have been published in the KCDB.. This is a comparison of inAC/DC voltage transfer difference at low voltages in the field of Electricity and Magnetism, carried out betwween BEV (Austria) and BIM (Bulgaria).
Density - COOMET
The comparison COOMET.M.D-S1 has been approved and can be consulted in the KCDB. This is a comparison of density in the field of Mass and related quantities in which 5 state economies participated.
Key comparison in neutron emission - CCRI
The comparison CCRI(III)-K9.AmBe.1 has been approved and can be consulted in the KCDB. This is a bilateral comparison of neutron emission, a quantity notably associated with nuclear fission processes, in the field of Ionizing Radiation between NPL (United Kingdom) and NIM (China).. The CCRI(III)-K9.AmBe.1 is linked to CCRI(III)-K9.AmBe via the NPL (United Kingdom) who participated in both comparisons.
Key Comparison CCTF-K001.UTC
The results of the key comparison CCTF-K001.UTC are updated on a monthly basis, and the KCDB web gives access to the calculation of the reference time scale UTC (Coordinated Universal Time), carried out by the BIPM, over the last twelve months.
