Hydranal CRMs serve as a reference point. They are traceable to high-purity materials of well-established purity and/or SI units. Additionally they are verified against internationally accepted standards from national metrological institutes such as NIST (National Institute of Standards & Technology, USA) or NMIJ (National Metrology Institute of Japan). In addition to traceability to accepted references, Hydranal CRMs have a well-defined mass fraction and highly accurate measurement of uncertainty which can be found in the Certificate of Analysis (CoA).
