Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO9713 was prepared by Technical Committee ISO/TC150, Implants for surgery,
Subcommittee SC 3, Neurosurgical implants.
This second edition cancels and replaces the first edition (ISO 9713:1990), which has been technically revised.

ISO 9713:2002(E)
Introduction
Magnetic fields of considerable strength [e.g. 0,2 T to 2,0 T (tesla) or more] are used in medicine with increasing
frequency as part of diagnostic techniques such as magnetic resonance imaging (MRI). Exposure to electromagnetic
radiation may pose a hazard to patients who have intracranial aneurysm clips. Clips with magnetic properties (dia-,
para-, antiferro-, ferro- and/or ferrimagnetic) become magnetized when subjected to a magnetic field and under this
condition are liable to directing forces. These forces may result in the clip being removed from the aneurysm that it
was intended to occlude and even being moved through the tissues. Because of the very high field strengths, even
materials normally regarded as non-magnetic may exhibit some response to the magnetic field, such as minimal
deflection or rotation. It is therefore essential that aneurysm clips have weakly or non-magnetic properties.
Compounds of certain non-magnetic elements may, when processed, have strong magnetic properties. The opposite
also occurs. The work done at manufacture may have an additional effect. However, material normally regarded as
non-magnetic may exhibit some response when subjected to MRI levels of field strength.
A secondary effect is that the presence of a metallic clip may interfere with the MRI process, resulting in deterioration
of the quality of the scanning image.
One of the main intentions of this International Standard is to help to ensure that appropriate and comparable
information is supplied for each clip in order to facilitate the choice of the correct clip by the surgeon. The closing
force of the clip is an important factor in the selection process, and this International Standard requires that the
manufacturers determine the closing force in a uniform manner and state this value on the labelling. The actuation of
some types of clip can unduly result in a reduction of the closing force.
