Sodium chloride (NaCl) is a volumetric standard manufactured under rigorous conditions and analyzed with the highest possible precision. The content of the standard is measured by volumetric argentometric titration and the measurement can be traced back to NIST SRM. Its certified value and uncertainty measurement are in accordance with ISO Guide 35.

This certified reference material (CRM) is produced in accordance with ISO 17034 and characterized in accordance with ISO/IEC 17025. This CRM is traceable to SI unit kg and measured against primary material from a National Metrology Institute (NMI), e.g. NIST.
