scope:

This part of ISO 18562 specifies tests for the emissions of VOLATILE ORGANIC COMPOUNDS (VOCs) from the GAS PATHWAYS of a MEDICAL DEVICE, its parts or ACCESSORIES, which are intended to provide respiratory care to a PATIENT in all environments. The tests of this International Standard are intended to quantify emissions of VOCs that are added to the respirable gas stream by the materials of the GAS PATHWAY. This International Standard establishes acceptance criteria for these tests. This International Standard addresses potential contamination of the gas stream arising from the GAS PATHWAYS, which is then conducted to the PATIENT. This Standard applies over the EXPECTED SERVICE LIFE of the MEDICAL DEVICE in NORMAL USE, and should take into account the effects of any intended processing or reprocessing. This International Standard 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).
