The authors evaluated four methods for determining chlorine residuals in water. Two membrane electrodes, a potentiometric electrode, and a continuous total chlorine analyzer were used by analysts to measure free or total chlorine in quality assurance samples and in tap water samples. Amperometric titration was used as a referee method. The statistical analyses of the evaluations are presented in this paper. Average precision of all analysts and of individual analysts is considered for each method.
