Growing safety requirements for respiratory medical devices - ISO 18562 standards

For many, a deep relaxing breath is not possible without a respiratory medical device. These people rely on it to a great extent – and any contamination of these airpath components could pose health hazards. Such devices are being regulated under the ISO 18562(biocompatibility evaluation of breathing gas pathways in healthcare applications) which is recognized by the FDA for biocompatibility evaluation of breathing gas pathways applications.

Tests under ISO 18562 aim to secure respiratory tract safety

The ISO 18562 standards outlines the biocompatibility evaluation of breathing gas pathways in healthcare applications. 
The parts or accessories which are intended to provide respiratory care or supply medicines via the respiratory tract to a patient in all environments are subject to biological evaluation detailed in ISO 18562. The standards cover ISO 18562-1: evaluation and testing within a risk management process, ISO 18562-2: tests for emissions of particulate matter , ISO 18562-3: tests for emissions of (VOCs) and ISO 18562-4: Tests for leachables in condensate.
