All USP volumetric solutions are prepared with raw materials which meet or exceed requirements of the American Chemical Society. Where no A.C.S. specifications exist, chemicals of highest purity available are used. All aqueous solutions are prepared using high purity, deionized water which meets requirements for ASTM Type 1 Reagent Grade Water.

All volumetric solutions, if practicable, are to be prepared, standardized, and used at the standard temperature of 25. If a titration is carried out with the volumetric solution at a markedly different temperature, standardize the volumetric solution used as the titrant at that different temperature, or make a suitable temperature correction.
