The reference material hierarchy includes five major quality grades, from national metrology and other primary standards to Certified Reference Materials (CRMs), Reference Materials (RMs), Analytical Standards, and research grade or research chemicals. Level of certification and traceability requirements increase for each higher level.

More than 90 different reference materials are distributed by the Agency. Each of these is characterised for analytes belonging to one of the following groups: Radionuclides, Trace Elements and Methyl Mercury, Organic Compounds, Stable Isotopes. The IAEA is the world's largest supplier of matrix reference materials characterised for radionuclides.
