INTRODUCTION
In response to requests for harmonization between the current European and International
standards for anaesthetic workstations this standard has been developed by the
IEC/ISO Joint Working Group to specify requirements for ANAESTHETIC SYSTEMS supplied
complete, as well as requirements for individual devices which are intended to be part of an
ANAESTHETIC SYSTEM. It applies in conjunction with IEC 60601-1:1988 (Including all
amendments) hereafter referred to as the General Standard. As stated in 1.3 of
IEC 60601-1-1988, the requirements in this standard take priority over those of the General
Standard.
This standard has been structured to allow USERS to configure an ANAESTHETIC SYSTEM in
conformance with professional guidelines and to meet the needs of their clinical practice.
In order to achieve this aim, the standard identifies particular requirements pertinent to
specific devices, and to their associated MONITORING DEVICE(S), ALARM SYSTEM(s) and
PROTECTION DEVICE(S), and defines the interfaces. This standard also specifies requirements
for optional devices, together with their respective MONITORING DEVICE(S), ALARM SYSTEM(S)
and PROTECTION DEVICE(S).
The indicated requirements are followed by specifications for the relevant tests. An asterisk
(*) denotes clauses for which there is a rationale comment in Annex AA. It is considered that
knowledge of the reasons for these requirements will facilitate the proper application of the
standard and be of use in any revision that may be necessitated by changes in clinical
practice or as a result of developments in technology.
NOTE The decimal separator for all numeric values is "," (comma).
The following graphic representation of the structure of this standard is being provided for
informational purposes only.
