Protective devices against diagnostic medical X-radiation -- Part 1: Determination of attenuation properties of materials
Applies to materials in sheet form used for the manufacturing of protective devices against X-radiation of radiation qualities generated with X-ray tube voltages up to 400 kV and a total filtration of up to 3,5 mm Cu. This part 1 is not intended to be applied to protective devices when these are to be checked for the presence of their attenuation properties before and after periods of use.

INTERNATIONAL ELECTROTECHNICAL COMMISSION
PROTECTIVE DEVICES AGAINST DIAGNOSTIC
MEDICAL X-RADIATION –
Part 1: Determination of attenuation properties of materials
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 cooperation 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, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
They have the form of recommendations for international use published in the form of standards, technical
3)
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.
International Standard IEC 1331-1 has been prepared by sub-committee 62S: Diagnostic
imaging equipment, of IEC technical committee 62: Electrical equipment in medical
practice.
The text of this part is based on the following documents:
DIS Report on voting
62B(CO)75
62B(CO)70
Full information on the voting for the approval of this part can be found in the report on
voting indicated in the above table.
Annex A forms an integral part of this standard.
