Breathing system filters for anaesthetic and respiratory use - Salt test method to assess filtration performance Ingestion-build-68772 PD IEC/TR 60601‑4‑3:2018 has made1 Scope This part of ISO 23328 gives a short term airborne sodium chloride particle challenge test method for assessing the filtration performance of breathing system filters (BSF) intended for the filtration of respired gases. This part of ISO 23328 is applicable to BSF used with a clinical breathing system. It is not applicable to other types of filter, e. g. those designed to protect vacuum sources or gas sample lines, to filter compressed gases,
