The results of 192 analyses for free available chlorine were obtained from each of 16 participating laboratories. These data were statistically analyzed to determine whether the DPD, FACTS, and amperometric titration methods were equivalent. This analysis indicated that FACTS is equivalent to both DPD and amperometric titration.
