SR EN ISO 18562-4:2020

ISO 18562-4:2017 specifies tests for substances leached by liquid water condensing into gas pathways of a medical device, its parts or accessories, which are intended to provide respiratory care or supply substances via the respiratory tract to a patient in all environments. The tests of this document are intended to quantify hazardous water-soluble substances that are leached from the medical device, its parts or accessories by condensate and then conveyed by that liquid to the patient. This document establishes acceptance criteria for these tests. ISO 18562-4:2017 addresses potential contamination of the gas stream arising from the gas pathways, which is then conducted to the patient. ISO 18562-4:2017 applies over the expected service life of the medical device in normal use and takes into account the effects of any intended processing or reprocessing ISO 18562-4:2017 does not address biological evaluation of the surfaces of gas pathways that are in direct contact with the patient. The requirements for direct contact surfaces are found in the ISO 10993 series. Medical device
