This document specifies:
—     the general principles governing the biological evaluation within a risk management process of 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 general categorization of gas pathways based on the nature and duration of their contact with the gas stream;
—     the evaluation of existing relevant data from all sources;
—     the identification of gaps in the available data set on the basis of a risk analysis;
—     the identification of additional data sets necessary to analyse the biological safety of the gas pathway;
—     the assessment of the biological safety of the gas pathway.
This document covers general principles regarding biocompatibility assessment of medical device materials, which make up the gas pathway, in normal use and normal condition. This document does not cover biological hazards arising from mechanical damage.
The other parts of ISO 18562 cover specific tests that address potentially hazardous substances that are added to the respirable gas stream and establish acceptance criteria for these substances.
This document addresses potential contamination of the gas stream arising from the gas pathways within the medical device, which might then be conducted to the patient.
This document applies over the expected lifetime of the medical device when operated according to the instructions for use. This includes degradation arising from exposure to environmental conditions as well as cleaning, disinfection and sterilisation (i.e. processing). It also includes user action or inaction (omission) that leads to an unintended or unexpected outcome (result) (i.e. use error). It does not include conscious/intentional action or inaction that violates the instructions for use and is beyond reasonable risk control by the manufacturer (i.e. abnormal use).
This document does not address biological evaluation of the surfaces of medical devices that have direct contact with the patient or user. 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 equipment, 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 system filters and Y-pieces as well as any breathing accessories intended to be used with such medical 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 (all parts).

This document specifies tests for the emissions of particulate matter 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 particles from 0,25 µm diameter to 10 µm diameter that are emitted by the medical device, its parts or accessories into the respirable gas stream. This document establishes acceptance criteria for these tests.
This document does not address nanoparticles. Insufficient data exist to establish exposure limits for particles less than 0,25 µm diameter.
This document does not address particles larger than 10 µm diameter. These particles are deposited in the nasal cavity. Additional information can be needed for medical devices or accessories that bypass the nose. This is outside the scope of this document but can be required by some authorities having jurisdiction.
This document therefore adopts the same approach as the US Environmental Protection Agency (EPA) in setting limits based solely on particle size and not their chemistry.

NOTE 1       Smaller and larger particles could also present biological hazards, and additional information outside the scope of this document can be needed to meet requirements of some authorities having jurisdiction.
ISO 18562-2:2017 therefore adopts the same approach as the US Environmental Protection Agency (EPA) in setting limits based solely on particle size and not their chemistry.
ISO 18562-2:2017 addresses potential contamination of the gas stream arising from the gas pathways, which is then conducted to the patient.
ISO 18562-2:2017 applies over the expected service life of the medical device in normal use and takes into account the effects of any intended processing or reprocessing.
ISO 18562-2:2017 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, 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.
ISO 18562-2:2017 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 (all parts).

ISO 18562-1:2017 specifies:
-      the general principles governing the biological evaluation within a risk management process of 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 general categorization of gas pathways based on the nature and duration of their contact with the gas stream;
-      the evaluation of existing relevant data from all sources;
-      the identification of gaps in the available data set on the basis of a risk analysis;
-      the identification of additional data sets necessary to analyse the biological safety of the gas pathway;
-      the assessment of the biological safety of the gas pathway.
ISO 18562-1:2017 covers general principles regarding biocompatibility assessment of medical device materials, which make up the gas pathway, but does not cover biological hazards arising from any mechanical failure, unless the failure introduces a toxicity risk (e.g. by generating particulates). The other parts of ISO 18562 cover specific tests that address potentially hazardous substances that are added to the respirable gas stream and establish acceptance criteria for these substances.
ISO 18562-1:2017 addresses potential contamination of the gas stream arising from the gas pathways within the medical device, which might then be conducted to the patient.
ISO 18562-1:2017 applies over the expected service life of the medical device in normal use and takes into account the effects of any intended processing or reprocessing.
ISO 18562-1:2017 does not address biological evaluation of the surfaces of medical devices 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 equipment, oxygen concentrators, nebulizers, low-pressure hose assemblies, humidifiers, heat and moisture exchangers, respiratory gas monitors, respiration monitors, masks, mouth pieces, resuscitators, breathing tubes, breathing system filters and Y-pieces as well as any breathing accessories intended to be used with such medical 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.
ISO 18562-1:2017 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 (all parts).
Future parts might be added to address other relevant aspects of biological testing including additional contamination that might arise from the gas pathway because of the presence of drugs and anaesthetic agents added to the gas stream.

ISO 8185:2007 is a particular standard based on IEC 60601-1:1988 and its Amendments, Amd. 1:1991 and Amd. 2:1995.
ISO 8185:2007 includes requirements for the basic safety and essential performance of humidification systems. It also includes requirements for individual devices specified for use in humidification systems such as heated breathing tubes (heated-wire breathing tubes) and devices intended to control these heated breathing tubes (heated breathing tube controllers). ISO 5367 specifies other safety and performance requirements for breathing tubes.
NOTE Heated breathing tubes are medical electrical equipment and are subject to the requirements of IEC 60601-1.
ISO 8185:2007 also includes requirements for active HME (heat and moisture exchanger) devices, which actively add heat and moisture to increase the humidity level of the gas delivered from the HME to the patient. It is not applicable to passive HMEs, which return a portion of the patient's expired moisture and heat to the respiratory tract during inspiration without adding heat and moisture. ISO 9360-1 and ISO 9360-2 specify safety and performance requirements for passive HMEs and describe methods for testing performance.
Respiratory tract humidifiers can be gas-powered, electrically-powered, or both. However, ISO 8185:2007 has been prepared as a particular standard based on IEC 60601-1, which gives general requirements for all aspects of safety, not only electrical safety, and many of the requirements are therefore applicable to humidifiers not powered by electricity.
ISO 8185:2007 is not applicable to devices commonly referred to as "room humidifiers" or humidifiers used in heating, ventilation and air conditioning systems, or humidifiers incorporated into infant incubators.
ISO 8185:2007 is not applicable to nebulizers used for the delivery of drugs to patients.
