Description / Abstract:
General
This International Standard is addressed to the manufacturer
and/or supplier of water treatment systems and/or devices used for
the express purpose of providing water for hemodialysis or related
therapies.
Inclusions
This International Standard covers devices used to treat water
intended for use in the delivery of hemodialysis and related
therapies, including water used for: (1) the preparation of
concentrates from powder or other highly concentrated media at a
dialysis facility; (2) the preparation of dialysis fluid, including
dialysis fluid that can be used for the preparation of substitution
fluid; (3) the reprocessing of dialyzers for multiple uses.
Included within the scope of this International Standard are all
devices, piping and fittings between the point at which potable
water is delivered to the water treatment system, and the point of
use of the dialysis water. Examples of devices included within the
scope of this International Standard are water purification
devices, online water quality monitors (such as conductivity
monitors), and piping systems for the distribution of dialysis
water.
Exclusions
Excluded from the scope of this International Standard are
dialysis fluid supply systems that proportion water and
concentrates to produce dialysis fluid, sorbent dialysis fluid
regeneration systems that regenerate and recirculate small volumes
of the dialysis fluid, dialysis concentrates, hemodiafiltration
systems, hemofiltration systems, systems that process dialyzers for
multiple uses, and peritoneal dialysis systems. Some of these
devices, such as dialysis fluid delivery systems and concentrates,
are addressed in other International Standards. Also excluded from
the scope of this International Standard are requirements for the
ongoing monitoring of the purity of water used for dialysis fluid,
concentrate preparation, or dialyzer reprocessing.
