IEC 62570:2014 applies to the practice of marking of items that might be used in the magnetic resonance (MR) environment. The 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. The standard specifies the permanent marking of items, which are used in an MR environment, by means of terms and icons. MR image artifacts are not considered to be a performance issue and so are not addressed in this international standard practice. IEC 62570 is integrating the unmodified text of ASTM F2503-13. It has been developed by subcommittee 62B: Diagnostic imaging equipment, of IEC technical committee 62: Medical equipment in medical practice, in collaboration with ASTM.
