Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed
for the different types of document should be noted (see www.iso.org/directives or
www.iec.ch/members_experts/refdocs).

declarations received (see https://patents.iec.ch).
Any trade name used in this document is information given for the convenience of users and does not

This document was prepared by INCITS (as INCITS 572-2021) and drafted in accordance with its editorial
rules. It was assigned to Joint Technical Committee ISO/IEC JTC 1, Information technology, and adopted
under the “fast-track procedure”.
