Biocompatibility evaluation of breathing gas pathways in healthcare applications - Part 3: Tests for emissions of volatile organic substances (ISO 18562-3:2024)
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 that are in direct contact with the patient. The requirements for direct contact surfaces are found in the ISO 10993 series.
Medical devices, parts or accessories containing gas pathways that are addressed by this document include, but are not limited to, ventilators, anaesthesia workstations (including gas mixers), breathing systems, oxygen conserving devices, oxygen concentrators, nebulizers, low-pressure hose assemblies, humidifiers, heat and moisture exchangers, respiratory gas monitors, respiration monitors, masks, medical respiratory personal protective equipment, mouth pieces, resuscitators, breathing tubes, breathing systems filters, Y-pieces and any breathing accessories intended to be used with such devices. The enclosed chamber of an incubator, including the mattress, and the inner surface of an oxygen hood are considered to be gas pathways and are also addressed by this document.
This document does not address contamination already present in the gas supplied from the gas sources while medical devices are in normal use.
EXAMPLE Contamination arriving at the medical device from gas sources such as medical gas pipeline systems (including the non-return valves in the pipeline outlets), outlets of pressure regulators connected or integral to a medical gas cylinder or room air taken into the medical device is not addressed by ISO 18562 series.
This document is intended to be read in conjunction with ISO 18562-1.

Introduction
This document is intended to protect patients connected to medical devices from excessive amounts
of volatile organic substances that arise from within the gas pathways of those medical devices. This
document represents the application of the best-known science by addressing the risks from potentially
hazardous volatile organic substances being conveyed to the patient by the gas stream.
This document is intended to cover the biological evaluation of gas pathways of medical devices within
a risk management process, as part of the overall medical device evaluation and development. This
approach combines the review and evaluation of existing data from all sources with, where necessary,
the selection and application of additional tests.
[1]
In general, the ISO 10993 series is intended to cover the biological evaluation of medical devices.
However, the ISO 10993 series does not appropriately address the biological evaluation of the gas
pathways of medical devices. For example, the ISO 10993 tests do not detect VOCs.
It is not within the scope of this document to address contamination arising from the source of the
breathing gases entering such medical devices, but rather only address the potential contamination
generated from within the medical device itself. This contamination might be from the original
manufacturing process or generated by the medical device itself during use.
This document is concerned with volatile organic substances that could be conveyed to the patient
by the breathing gases. Volatile organic substances can have health effects ranging from unpleasant
odour and irritation of the mucous membranes to possible long-term effects on the nervous system. It is
accepted that there is no point in setting levels that are lower than those found in air that people might
breathe every day.
The tests for the presence of volatile organic substances generated by respiratory medical devices are
based on advanced laboratory practice and require specialist training and equipment to generate
meaningful results.
The methods to determine the acceptable levels of contamination are contained in ISO 18562-1.
In this document, the following print types are used:
— requirements and definitions: roman type;
— informative material appearing outside of tables, such as notes, examples and references: in smaller
type. Normative text of tables is also in a smaller type;
— terms defined in Clause 3 of this document or as noted and test specifications: italic type;
This document has been prepared in consideration of:
