SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT

FOR MEASUREMENT, CONTROL, AND LABORATORY USE –

Part 2-091: Particular requirements for CABINET X-RAY SYSTEMS

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.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 61010-2-91 has been prepared by IEC technical committee 66:
Safety of measuring, control and laboratory equipment.
It has the status of a group safety publication as specified in IEC Guide 104.
The text of this standard is based on the following documents:
FDIS Report on voting
66/462/FDIS 66/470/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

– 4 – 61010-2-091 © IEC:2012
This Part 2-091 is intended to be used in conjunction with IEC 61010-1. It was established on

the basis of the third edition (2010). Consideration may be given to future editions of, or

amendments to, IEC 61010-1.
This Part 2-091 supplements or modifies the corresponding clauses in IEC 61010-1 so as to

convert that publication into the IEC standard: Particular requirements for CABINET X-RAY

SYSTEMS.
Where a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies

as far as is reasonable. Where this part states “addition”, “modification”, “replacement”, or

“deletion”, the relevant requirement, test specification or note in Part 1 should be adapted

accordingly.
In this standard:
a) the following print types are used:
– requirements: in roman type;
– NOTES: in small roman type;
– conformity and tests: in italic type;
– terms used throughout this standard which have been defined in Clause 3: SMALL
ROMAN CAPITALS.
b) subclauses, figures, and tables which are additional to those in Part 1 are numbered
starting from 101; additional annexes are lettered starting from AA and additional list
items are lettered from aa).
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The following differing practices exist in the countries indicated below:
– 7.1: Conveyor systems are required to meet the requirements of
ANSI/ASME B20.1 (USA).
A list of all parts of the IEC 61010 series, published under the general title Safety
requirements for electrical equipment for measurement, control, and laboratory use, can be
found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be

• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
