Definition of ASTM D1193-91

Type 1 water quality systems typically have measurements of less than 0. TOC is typically measured in parts per billion ppbwith Type 1 water systems having less than 10 ppb. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? High TOC measurements can be indicative of bacterial biofilm growth within a water supply or other upstream biological contamination.

Type I reagent water may be produced with alternate technologies as long as the appropriate constituent speci? These issues are very complex and extensive. Last previous edition D— Depending on the water type required and the applications performed, container material and cleaning procedures must be chosen appropriately.



Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Water quality is measured by examining a set of parameters from a water sample and comparing that to set values to achieve a water purity rating. Endotoxins are lipopolysaccharide molecules released when bacterial cells die.
