Diagnostic X-ray imaging equipment - Characteristics of general purpose and mammographic anti-scatter grids
Deals with the definitions, determination and indication of characteristics of anti-scatter grids used in diagnostic X-ray imaging equipment, in order to reduce the incidence of scattered radiation, produced particularly in the body of the patient, upon the image reception area and thus to improve the contrast of the X-ray pattern. Only linear grids are considered in this standard. This standard is intended to be applied for the demonstration of the characteristics of anti-scatter grids under test conditions.

Traite des définitions, de la détermination et de l'indication des caractéristiques des grilles antidiffusantes utilisées dans les équipements de diagnostic par imagerie à rayonnement X, afin de réduire l'influence du rayonnement diffusé produit en particulier dans le corps du patient, sur la surface réceptrice de l'image et d'améliorer ainsi le contraste de l'image radiologique potentielle. Cette norme ne traite que des grilles linéaires. Il est prévu que cette norme soit appliquée à la démonstration des caractéristiques des grilles antidiffusantes dans des conditions d'essai.

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 specifications, 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 60627 has been prepared by subcommittee 62B: Diagnostic
imaging equipment, of IEC technical committee 62: Electrical equipment in medical practice.
This second edition cancels and replaces the first edition published in 1978, and constitutes a
technical revision. It also cancels and replaces IEC 61953 published in 1997 which is
incorporated in this standard technically unchanged.
The text of this standard is based on the following documents:
FDIS Report on voting
62B/436A/FDIS 62B/441/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.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
Annexes A and B form an integral part of this standard.

INTRODUCTION
The first edition of IEC 60627 was intended for ANTI-SCATTER GRIDS used in general radio-
graphy and is not appropriate for ANTI-SCATTER GRIDS used in mammography. As a
consequence, a complementary standard IEC 61953 was published. During the preparation of
this latter standard, it became clear that a revision of IEC 60627 itself was necessary, and it
was decided to merge together the two standards covering ANTI-SCATTER GRIDS. Wherever
possible, a harmonized approach has been used. Where there are differences in this standa
