* the certified value is based on both gravimetric preparation, and instrumental analysis * the uncertainty is calculated as: U=ku

c,

where k is the multiplier for a 95% level of confidence interval (Table B.1 of Guidelines for Evaluating and

Expressing the uncertainty of NIST measurement results), and uc is the combinated standard uncertainty calculated acc. ISO Guide to the Expression of

Uncertainty in Measurement

Measured density: 1.021 g/cm3 at 20 0C

This solution was manufactured using purified acids by subboiling, 18 MOhm double deionised water, calibrated Class A glassware, and high density polyethylene bottle, decontaminated by leaching with high purity acids, 18 MOhm deionised water and triple rinse. Balances are calibrated with weights, traceable to NIST. Stability and accuracy are guaranteed until the date shown at the label provided that the solution is tightly capped and stored under normal laboratory conditions.This certification is nullified if the standard solution is damaged, contaminated, or modified.

Certification date:Shelf Life* :Expiry date** :

02.07.2009until 08.2010………………(Should not exceed 6 months from date of opening within the shelf-life period.)

* The shelf life is the specified length of time prior to use for which a properly packaged and stored standard solution remains within the specified uncertainty.

** The expiry date is the date after which the certification of standard solution becomes invalid (due to evaporation losses and frequent use).
