FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60601-2-8 has been prepared by subcommittee 62B: Diagnostic
imaging equipment, of IEC technical committee 62: Electrical equipment in medical practice.
The text of this standard is based on the following documents:
Six Months’ Rule Report on voting
62B(CO)49 62B(CO)64
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Subclauses, figures or tables that are additional to those of the General Standard are
numbered starting from 101; additional annexes are lettered AA, etc., and additional items aa),
bb), etc.
Annex AA is for information only.
Annex BB forms an integral part of this standard.
60601-2-8 Amend. 1 © IEC:1997 – 9 –
In this Particular Standard, the following print types are used:
– requirements, compliance with which can be tested, and definitions, in roman type;
– explanations, advice, general statements and exceptions: in small roman type;
– TERMS USED THROUGHOUT THIS PARTICULAR STANDARD WHICH HAVE BEEN LISTED IN ANNEX AA
AND DEFINED IN CLAUSE 2, OR IN THE GENERAL STANDARD 60601-1 AND ITS COLLATERAL
STANDARDS OR IN IEC 60788: SMALL CAPITALS.
Replace, throughout the Standard, the term “X-RAY GENERATOR” by “X-RAY EQUIPMENT”.
Add, after the foreword, the following new introduction:
INTRODUCTION
The use of X-RAY EQUIPMENT for RADIOTHERAPY purposes may expose the PATIENT to danger if
the EQUIPMENT fails to deliver the required dose to the PATIENT, or if the EQUIPMENT design does
not satisfy standards of electrical and mechanical safety. The EQUIPMENT may also cause
danger to persons in the vicinity if the EQUIPMENT itself fails to contain the RADIATION
adequately and/or if there are inadequacies in the design of the TREATMENT ROOM.
This Particular Standard establishes requirements to be complied with by the MANUFACTURERS
in the design and construction of therapeutic X-RAY EQUIPMENT. Clause 29 contains limits
beyond which INTERLOCKS prevent, INTERRUPT or TERMINATE IRRADIATION in order to avoid an
unsafe condition.
Clause 29 does not attempt to define 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 EQUIPMENT. It places limits on the degradation of EQUIPMENT
performance beyond which it can be presumed that a fault condition exists, e.g. a component
failure, and where an INTERLOCK then operates to prevent continued operation of the
EQUIPMENT.
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
EQUIPMENT at installation.

MEDICAL ELECTRICAL EQUIPMENT –
Part 2: Particular requirements for the safety of
therapeutic X-ray equipment operating in
the range 10 kV to 1 MV
60601-2-8 Amend. 1 © IEC:1997 – 11 –
1.1 Scope
Replace the text of this subclause by the following:
Addition:
This Particular Standard applies to therapeutic X-RAY EQUIPMENT with NOMINAL X-RAY TUBE
VOLTAGES in the range 10 kV to 1 MV when connected to alternating current SUPPLY MAINS.
1.2 Object
Replacement:
Replace the first paragraph of this subclause by the following:
This Particular Standard establishes requirements for the safety of therapeutic X-RAY
EQUIPMENT including the requirement for accuracy and reproducibility of performance to the
extent that these are related to RADIATION QUALITY and the quantity of IONIZING RADIATION
produced and thus must be considered as aspects of safety.
1.3.101 Relation to the General Standard
Replace the first two paragraphs by the following:
This Particular Standard shall be read in conjunction with IEC 60601-1 (1988) and its
amendments 1 (1991) and 2 (1995).
As in the General Standard, the requirements of this Particular Standard are followed by
compliance tests.
The numbering of sections, clauses and subclauses of this Particular Standard corresponds
with that of the General Standard. 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 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.
"Amendment" means that the clause or subclause of the General Standard is amended as
indicated by the text of this Particular Standard.
Replace the last paragraph on page 11 and the first paragraph on page 13, by the following
paragraph:
Where there is no corresponding section, clause or subclause in this Particular Standard, the
section, clause or subclause of the General Standard, although possibly not relevant, applies
without modification. Where it is intended that any part of the General Standard, although
possibly relevant, is not to be applied, a statement to that effect is given in this Particular
Standard. Unless otherwise stated, all clauses of the General Standard shall apply.
