1.1This international standard applies to the practice of marking of items that might be used in the magnetic resonance (MR) environment.
1.2The purpose of this practice is to mark items that might be brought into the MR environment and to recommend information that should be included in the marking.
1.3The standard specifies the permanent marking of items, which are used in an MR environment, by means of terms and icons.
1.4MR image artifacts are not considered to be a performance issue and so are not addressed in this international standard practice (see X1.5).
1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
