Non-specific requirements are covered by references to other European or Intedonal Stan-, listed in the nonnative referenc
15、es section. Since non-toxicity is anticipated to be the subject of a future stanard, this standard does not cover non-toxiciw. 1 scope This European Standard specifies requirements for sterile, single use haemodialysers, haemodiafilters, haemofiitm, haemoconcentrators and the extracorporeal circuits
16、 for these devices (including any integral accessory lines, such as fluid and infusion lines and lines for connection to pressure monitors) intended for renai care and cardiovascular use on humans.
