Det. Purity 99.5% Tolerance/Uncertainty+/- 1.0% 
The uncertainty/tolerance of this standard is calculated in accordance with the EURACHEWCITAC Guide-Quantifvina Uncertainty in Analytical Measurement-Second Edition.The uncertainty given is the expanded combined uncertainty and represents an estimated standard deviation equal to the positive square root of the total variance of the uncertainty of components.The expanded uncertainty is U which is Uc(y)*K,where Kis the coverage factor at the 95% confidencelevel(K=2).The expanded uncertainty is based on the combination of uncertainties associated w ith each individual operation involved in the preparation of this product
