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. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
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. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/IEC JTC 1, Information technology, SC 23,
Digitally recorded media for information interchange and storage.
This third edition cancels and replaces the second edition (ISO/IEC 16963:2015), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— minor enhancement has been made so that the stress condition and the disk testing location are
independent of each other and the cross-combinations of them are applicable; and
— minor editorial changes have been made to conform to the latest version of the ISO/IEC Directives
Part 2.
This corrected version of ISO/IEC 16963:2017 incorporates the following corrections:
— correction of the formula in E.3 that uses function ln L = ln L(β,σ) to express the Fisher information
matrix I in E.2.
