The new RMs IAEA-610, IAEA-611 and IAEA-612 have been characterised on the VPDB δ13 C scale in a mutually consistent way. The use of three RMs will allow a consistent realisation of the VPDB δ13 C scale with small uncertainty to be established, and to reach metrological compatibility of measurement results over several decades.
