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 of preparation, purity of neat materials, homogeneity, stability testing.
Traceability
The balances used for gravimetric measurements are calibrated with weights traceable to the national
standards. The calibration of the balances is verified annually by an external accredited
calibration service. This analysis method has been verified using an approach consistent with ISO 17034:2016 & ISO 17025:2017.
