This is an editorial correction to NSF/ANSI 53 - 2003. In section 4.4.2.1 of 2003, it states the exposure water should have a pH of 6.65 +/- 0.25, while the previous version specified a pH of 6.75 +/- 0.25. The previous version of 6.75 +/- 0.25 is correct, and this change has been made here in NSF/ANSI 53 - 2003e.
The point-of-use reverse osmosis drinking water treatment systems addressed by this Standard are designed to be used for the reduction of specific substances that may be present in drinking water supplies (public or private) considered to be microbiologically safe and of known quality (except that claims for the reduction of filterable cysts may be permitted). Systems covered by this Standard are intended for reduction of total dissolved solids (TDS) and other contaminants specified herein. Systems with components or functions covered under other NSF or NSF/ANSI Standards or Criteria shall comply with those applicable requirements.
