SR EN ISO 18562-3:2025

This document specifies tests for the emissions of volatile organic substances from the 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 emissions of volatile organic substances that are added to the respirable gas stream by the materials of the gas pathway. This document establishes acceptance criteria for these tests. NOTE            Gaseous emission of volatile organic substances includes emissions of volatile organic compounds, semi-volatile organic compounds and very volatile organic compounds. This document addresses potential contamination of the gas stream arising from the gas pathways of medical devices or accessories, which is then conducted to the patient. This document applies over the expected lifetime of the medical device in normal use and takes into account the effects of any intended processing. This document does not address biological evaluation of the surfaces of gas pathways
