FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates
closely with the International Organization for Standardization (ISO) in accordance with conditions determined
by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.

INTRODUCTION
The use of LIGHT ION BEAM ME EQUIPMENT for RADIOTHERAPY purposes may expose PATIENTS to
danger if the ME EQUIPMENT fails to deliver the required dose to the PATIENT, or if the ME
design does not satisfy standards of electrical and mechanical safety. The ME
EQUIPMENT
EQUIPMENT may also cause danger to persons in the vicinity if the ME EQUIPMENT itself fails to
contain the RADIATION adequately or if there are inadequacies in the design of the TREATMENT
ROOM.
This particular standard establishes requirements to be complied with by MANUFACTURERS in
the design and construction of LIGHT ION BEAM ME EQUIPMENT for use in RADIOTHERAPY; it does
not attempt to define their optimum performance requirements. Its purpose is to identify those
features of design that are regarded, at the present time, as essential for the safe operation of
such ME EQUIPMENT; it places limits on the degradation of ME EQUIPMENT performance beyond
which it can be presumed that a fault condition exists and where an INTERLOCK then operates
to prevent continued operation of the ME EQUIPMENT.
Clause 201.10 contains limits beyond which INTERLOCKS prevent, INTERRUPT or TERMINATE
IRRADIATION in order to insure that ESSENTIAL PERFORMANCE is maintained and to avoid an
unsafe condition. TYPE TESTS that are performed by the MANUFACTURER, or SITE TESTS, which
are not necessarily performed by the MANUFACTURER, are SPECIFIED for each requirement. It
should be understood that, before installation, a MANUFACTURER can provide a compliance
certificate relating only to TYPE TESTS. Data available from SITE TESTS should be incorporated
in the ACCOMPANYING DOCUMENTS, in the form of a SITE TEST report, by those who test the ME
EQUIPMENT at installation.
Closely related to this standard is IEC 62667 which is currently being developed. It specifies
test methods and reporting formats for performance tests of LIGHT ION BEAM ME EQUIPMENT for
use in RADIOTHERAPY, with the aim of providing uniform methods of doing so. The annex of
IEC 62667 provides forms for presenting performance values, measured per the methods
SPECIFIED.

Replacement:
In the IEC 60601 series, particular standards may modify, replace or delete requirements
contained in the general standard or collateral standards as appropriate for the particular
ME EQUIPMENT under consideration, and may add other BASIC SAFETY and ESSENTIAL
PERFORMANCE requirements.
A requirement of a particular standard takes priority over the general standard.
For brevity, IEC 60601-1 is referred to in this particular standard as the general standard.
Collateral standards are referred to by their document number.
The numbering of clauses and subclauses of this particular standard corresponds to that of
the general standard with the prefix “201” (e.g. 201.1 in this standard addresses the content
of Clause 1 of the general standard) or applicable collateral standard with the prefix “20x”
where x is the final digit(s) of the collateral standard document number (e.g. 202.4 in this
particular standard addresses the content of Clause 4 of the IEC 60601-1-2 collateral
standard, 203.4 in this particular standard addresses the content of Clause 4 of the
IEC 60601-1-3 collateral standard, etc.). The changes to the text of the general standard are
specified by the use of the following words:
“Replacement” means that the clause or subclause of the general standard or applicable
collateral standard is replaced completely by the text of this particular standard.

“Addition” means that the text of this particular standard is additional to the requirements of
the general standard or applicable collateral standard.
“Amendment” means that the clause or subclause of the general standard or applicable
collateral standard is amended as indicated by the text of this particular standard.
Subclauses, figures or tables which are additional to those of the general standard are
numbered starting from 201.101. However due to the fact that definitions in the general
standard are numbered 3.1 through 3.139, additional definitions in this standard are
numbered beginning from 201.3.201. Additional annexes are lettered AA, BB, etc., and
additional items aa), bb), etc.
Subclauses, figures or tables which are additional to those of a collateral standard are
numbered starting from 20x, where “x” is the number of the collateral standard, e.g. 202 for
IEC 60601-1-2, 203 for IEC 60601-1-3, etc.
The term “this standard” is used to make reference to the general standard, any applicable
collateral standards and this particular standard taken together.
Where there is no corresponding clause or subclause in this particular standard, the clause or
subclause of the general standard or applicable collateral standard, although possibly not
relevant, applies without modification; where it is intended that any part of the general
standard or applicable collateral standard, although possibly relevant, is not to be applied, a
statement to that effect is given in this particular standard.
