Uncertainty
The certified value(s) and uncertainty(ies) are determined in accordance with ISO 17034 with an 95%confidence level (k=2). Uncertainty is based on the Total Combined Uncertainty, including uncertainties ofcharacterisation, homogeneity and stability testing. Stability values are based on real evidence opposed tosimulation.
The producer certifies that this reference material meets the specification stated in this certificate until theexpiry date, provided it is stored unopened at the recommended temperature herein. Product warranties forthis reference material are set out in the terms and conditions of purchase.
Intended
UseThis RM is intended for use in a laboratory as a calibration and quality control standard or in methodCERTIFIEDPurityCERTIFIEDExpanded Uncertainty(U)99.5% 0.5%development for analytical techniques.
Safety
Proper precautions should be observed while handling. See Safety Data Sheet.
Traceability
The balances used for gravimetric measurements are calibrated with weights traceable to the nationalstandards (DKD). The calibration of the balances is verified daily internally and annually by an externalaccredited calibration service. Chromatographic methods are traceable to the International Systemof Units(SI).
Homogeneity
Random replicate samples of the final packaged RM have been analysed to prove homogeneity compliant with ISO 17034.
Storage
The RM should be stored in the original sealed container at the indicated temperature.
Instructions for use
It is recommended to use 1 mg as the minimum sample size and if less material is used, to increase thecertified uncertainty by a factor of two for half sample and four for a quarter of sample. If storage afteropening is necessary, the RM should be tightly closed and kept from light and moisture. If the RMwas in asealed ampoule, it should be transferred to a vial with minimum head space.
