This specification describes the required characteristics of reagent waters. Four types of waters have been specified, with three additional grades that can be applied to the four types. The grade specifications specifically address contaminants of microbiological origin. Historically, reagent water types I, II, III, and IV have been linked to specific processes for their production. Starting with this revision, these types of waters may be produced with alternate technologies as long as the appropriate constituent specifications are met. The electrical conductivity and resistance, pH, silica, sodium, chlorides, TOC, endotoxins, and microbiological contamination shall be tested to meet the requirements prescribed.
