REFERENCE MATERIAL CERTIFICATE
Reference Material
This certificate is designed in accordance with ISO 17034 and ISO Guide 31. This reference material (RM) was designed,produced and verified in accordance with ISO/IEC 17025, ISO 17034 and a registered quality management system ISO9001.
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.
Intended Use
This RM is intended for use in a laboratory as a calibration and quality control standard or in methoddevelopment for analytical techniques.
Safety
Proper precautions should be observed while handling. See Safety Data Sheet
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.
