ASTM F2503-23

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F2503 − 20 F2503 − 23
Standard Practice for
Marking Medical Devices and Other Items for Safety in the
1
Magnetic Resonance Environment
This standard is issued under the fixed designation F2503; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This international standard applies to the practice of marking of items that might be used inpractice applies to medical devices
and other items that are anticipated to enter the magnetic resonance (MR) environment.
NOTE 1—“Medical devices and other items” will be referred to as “items” for the remainder of this practice.
1.2 The purpose of this practice is to mark items that might be brought into practice specifies the marking of items anticipated
to enter the MR environment and to recommend by means of terms and icons, and recommends information that should be included
in the marking.labeling.
1.3 The standard specifies the permanent marking of items, which are used in an MR environment, by means of terms and icons.
1.3 MR image artifacts are not considered to be a performance issue and so are not addressed in this international standard practice
in the scope of the mandatory portions of this practice because they do not present a direct safety issue resulting from specific
characteristics of the MR examination (see X1.5X1.12).
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
