Products used for treatment of swimming pool water. Powdered activated carbon1 Scope This European Standard is applicable to powdered activated carbon used for treatment of swimming pool water. It describes the characteristics of powdered activated carbon and specifies the requirements and the corresponding test methods for powdered activated carbon. It gives information on its use in swimming pool water treatment.

BS EN IEC 62933‑5‑2 specifies the safety requirements of an “electrochemical” ESS as a "system" to reduce the risk of harm or damage caused by the hazards of an electrochemical energy storage system due to interactions between the subsystems as presently understood
