Abstract
Titrimetry has wide-ranging applications for amount-of-substance measurements and can be used for both metrological and working-level measurements. This paper is a review of the potential of titrimetry as a primary method. Many parts of a traceability system are in place but these are not formally recognized at either a national or international level. Further work is required to assess existing expertise and to establish internationally recognized primary reference materials (standards) and measurement procedures.
