12、ide 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
13、fields of mutual interest. Other international organizations, governmental and no ngovernmental, in liaison wit h I S O a n d I E C , a l s o t a k e p a r t i n t h e work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedure
14、s 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 o
15、f 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 i
16、dentified 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).

17、tion on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html. ISO/IEC 17826 was pr
18、epared by SNIA and was adopted, under the PAS procedure, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. This second edition cancels and replaces the first edition (ISO/IEC 17826:2012), which has been technically re
19、vised.
