The reference material IAEA-611 (CaCO3), similarly as the reference materials IAEA-610 and IAEA-612, can serve as second scale-anchor together with IAEA-603 for realization of the VPDB δ13C scale.

The reference materials IAEA-610, IAEA-611 and IAEA-612 were prepared with the aim to replace the reference material LSVEC and to address requirements for all possible applications including the strictest requirements for δ13C in greenhouse gas observations. Description of the material, its intended use, results of the characterisation and the values assignment can be found in the Reference Sheet. The material IAEA‑611 is supplied as 0.5 g units in flame sealed glass ampoules.
