Abstract: The detection of active chlorine content in the phosphate ester fire-resistant fluids is of great importance for the electro-hydraulic control system. In this paper, the principles, instruments and operating conditions of automatic potentiometric titration method to detect active chlorine content in the phosphate ester fire-resistant fluids are studied. The inter-laboratory experiments involving eight laboratories and five samples are conducted and the results are evaluated. In terms of repeatability and reproducibility, limit of detection, recovery rate and accuracy of measurement, the proposed automatic potentiometric titration testing method is capable of detecting the active chlorine content in the phosphate ester fire-resistant fluids with high accuracy and efficiency as well as fast analysis of measurement but simple sample treatment procedures and low requirements for instrument configuration. Therefore it can be promoted for practical usage in the field of power industry.

Key words: electro-hydranlic control system, phosphate ester fire-resistant fluids, active chlorine, automatic potentiometric titration testing method, evaluation of method
