European foreword
This document (prEN 17180:2017) has been prepared by Technical Committee CEN/TC 102 “Sterilizers
for medical purposes”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
This document is a working document provided by DIN mirror group for gas sterilizer as a new work
item proposal.
The following referenced documents are indispensable for the application of this document. For
undated references, the edition of the referenced document (including any amendments) listed below
applies. For dated references, only the edition cited applies. However, for any use of this standard
within the meaning of Annex ZA, the user should always check that any referenced document has not
been superseded and that its relevant contents can still be considered the generally acknowledged
state-of-art.
When an IEC or ISO standard is referred to in the ISO standard text, this should be understood as a
normative reference to the corresponding EN standard, if available, and otherwise to the dated version
of the ISO or IEC standard as listed below.

Introduction
This European Standard specifies minimum requirements and test methods for sterilizers processing,
typically, below 80 °C, performing a low temperature sterilization process using a composition of water
O ) as sterilizing agent, vaporized and injected into the sterilizer chamber.
and hydrogen peroxide (H2 2
Vaporized hydrogen peroxide (VH O ) sterilizers are primarily used for the sterilization of thermolabile
2 2
medical devices in health care facilities, but can also be used during commercial production of medical
devices.
Like the other standardized low temperature sterilization processes using ethylene oxide (see EN 1422
and EN ISO 11135) or low temperature steam and formaldehyde (see EN 14180 and EN ISO 25424) the
VH O sterilization processes are specified by physical and chemical parameters and verified using
2 2
physical, chemical and microbiological means [ref]. The sterilizers operate automatically using pre-set
cycles.
The test methods and test equipment given could also be applicable to validation and routine control.
Validation and routine control of sterilization processes are essential to ensure their efficacy. This
standard does not cover validation and routine control of a VH O sterilization process. Harmonized
2 2
standards providing specific requirements for validation and routine control of VH O sterilization
2 2
processes are currently not available. EN ISO 14937 can provide general requirements and guidance on
how to perform validation and routine control of such processes.
Some VH O sterilizers have processes that demonstrate some level of inactivation of the causative
2 2
agents of spongiform encephalopathies such as scrapie, bovine spongiform encephalopathy and
Creutzfeldt-Jakob Disease. However, this inactivation is process, cycle and test protocol specific, and not
equipment specific, therefore this inactivation is outside the scope of this European Standard, and no
specific test methods are provided [ref].
Planning and design of products applying to this standard should consider not only technical issues but
also the environmental impact from the product during its life-cycle. Environmental aspects are
addressed in Annex H of this standard.
NOTE Specifications on operators safety are addressed in EN 61010-1, EN 61010-2-040 and are not repeated
in this standard. FprEN 60204-1 can also apply (see Annex G).
