dc.description.abstract Proftest SYKE carried out the proficiency test for the determination of chlorine, KMnO4, NO3, pH, turbidity, and urea in swimming pool waters in February 2017. In total, 23 participants joined in the proficiency test. The calculated value, the robust mean or the mean of the results reported by the participants was chosen as the assigned value for the concentration of measurands. The performance of the participants was evaluated by using z scores. In this proficiency test 85 % of the results were satisfactory when deviation of 0.2 pH units for pH determination and 8–30 % for the other measurands was accepted from the assigned value. Warm thanks to all the participants of this proficiency test! fi
