process definition, installation identification, operation identification, and maintaining
the effectiveness of the sterilization process;
--- Make more specific and refined technical requirements such as performance
identification, routine monitoring and control, etc.;
--- Add guidelines for implementing the ethylene oxide sterilization process.
This Part equivalently adopted ISO 11135-1.2007 Sterilization of Health Care Products –
Ethylene Oxide – Part 1.Requirements for Development, Validation and Routine Control of a
Sterilization Process for Medical Devices.

Sterilization of Health Care Products – Ethylene Oxide – Part 1.
Requirements for Development, Validation and Routine Control
of a Sterilization Process for Medical Devices
1 Scope
This Part of GB 18279 specifies requirements for the development, validation and routine
control of an ethylene oxide sterilization process for medical devices.
NOTE 1.Although the scope of this Part is limited to medical devices, it specifies requirements and
provides guidance that may be applicable to other health care products.
Sterilization processes validated and controlled in accordance with the requirements of this Part
are not assumed to be effective in inactivating the causative agents of spongiform
encephalopathies such as scrapie, bovine spongiform encephalopathy and Creutzfeld Jacob
disease. Specific recommendations have been produced in particular countries for the
processing of materials potentially contaminated with these agents.
NOTE 2.See for example YY/T 0771.1, YY/T 0771.2 and YY/T 0771.3.
This Part does not detail a specified requirement for designating a medical device as sterile.
NOTE 3 Attention is drawn to national or regional requirements for designating medical devices as
“sterile”. See for example EN 556-1 or ANSI/AAMI ST67.
This Part does not specify a quality management system for the control of all stages of
production of medical devices.
NOTE 4.The effective implementation of defined and documented procedures is necessary for the
development, validation and routine control of a sterilization process for medical devices. Such
procedures are commonly considered to be elements of a quality management system. It is not a
requirement of this Part to have a complete quality management system during manufacture or
reprocessing, but the elements of a quality management system that are the minimum necessary to control
the sterilization process are normatively referenced at appropriate places in the text (see in particular
Clause 4). National and/or regional regulations for the provision of medical devices might require
implementation of a complete quality management system and the assessment of that system by a third
party.
This Part does not specify requirements for occupational safety associated with the design and
operation of ethylene oxide sterilization facilities.
NOTE 5.For further information on safety, see examples in the Bibliography. National or regional
regulations may also exist.
NOTE 6.Ethylene oxide is toxic, flammable and explosive. Attention is drawn to the possible existence
in some countries of regulations giving safety requirements for handling ethylene oxide and for premises
in which it is used.
This Part does not cover sterilization by injecting ethylene oxide or mixtures containing
ethylene oxide directly into individual product packages, or continuous sterilization processes.
This Part does not cover analytical methods for determining levels of residual ethylene oxide
and/or its reaction products.
NOTE 7.For further information see ISO 10993-7.
NOTE 8.Attention is drawn to the possible existence of regulations specifying limits for the level of
ethylene oxide residues present on or in medical devices and products.
