This European Standard specifies requirements for dry and liquid concentrates to be diluted for use as dialysing fluids in haemodialysis or related therapies. It addresses chemical and microbiological quality and purity, handling and labelling of concentrates, the requirements for containers and the tests to monitor chemical and microbiological contents and quality of such concentrates.

This European standard does not address the final mixing and use of these concentrates or the treated water used in connection with haemodialysis and related therapies.

This European standard does not apply to dialysing fluid regeneration systems.
