8、tional 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
9、 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 infor
10、mation technology,ISO and IEC have established a joint technical committee,ISO/IEC JTC 1.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives,Part 2.The main task of the joint technical committee is to prepare International Standards.Draft International St
11、andards adopted by the joint technical committee are circulated to national bodies for voting.Publication as an International Standard requires approval by at least 75%of the national bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the su

14、hat the property referred to as the archival life of data recorded to optical media plays an increasingly important role for the intended applications.The existing standard test methodologies for recordable media include Magneto Optical media and recordable compact disk systems.It was agreed that th
15、e project represented by this document be undertaken in order to provide a methodology that includes the testing of newer,currently available products.The Optical Storage Technology Association(OSTA)initiated work on this subject and developed the initial drafts.Following that development,the projec
16、t was moved to Ecma International Technical Committee TC 31 for further development and finalization.OSTA and Ecma wish to thank the members and organizations in NIST,CDs21 Solutions,and DCAj for their support of the development of this document.ECMA-379 1st Edition was fast-tracked to ISO/IEC JTC 1 in August 2007 and during this process its editorial content was slightly modified.The approved International Standard was published as ISO/IEC 10995:2008 in April 2008.ECMA-379 2nd Edition is techni
