ISO/IEC Standard estimates life expectancy of DVDs.
May 21, 2008 -
Prepared by Ecma International and adopted by ISO/IEC Joint Technical Committee 1, Sub Committee 23, ISO/IEC 10955 provides outline of steps that can be taken to predict life expectancy for retrieving information stored on recordable or rewritable discs. Standard covers stress conditions, assumptions, ambient conditions, and evaluation system description, as well as specimen preparation, data acquisition procedure, and data interpretation.

As business and personal communications become increasingly digitized, the storage and preservation of information is evolving. Many organizations now rely on DVDs as a cost- and space-effective way of saving important records, as well as a convenient way to pass information along to customers and colleagues. A number of American National Standards ensure that these discs will perform as expected.
But once important information is stored on DVDs, how long will they last? The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) have issued a new standard that estimates the useful life of DVDs. ISO/IEC 10955: 2008: Information technology -- Digitally recorded media for information interchange and storage -- Test method for the estimation of the archival lifetime of optical media provides an outline of steps that can be taken to predict the life expectancy for retrieving information stored on recordable or rewritable discs.
ISO/IEC 10995 covers the following aspects: stress conditions assumptions ambient conditions evaluation system description specimen preparation data acquisition procedure data interpretation
The methodology includes the effects of temperature and relative humidity only, and does not account for additional environmental factors including exposure to light, corrosive gases, contaminants, handling, and variations in playback subsystems. It is expected that these factors would further shorten the retrievability of information on a disc.
ISO/IEC 10995:2008 was prepared by Ecma International and was adopted, under a special "fast track procedure," by ISO/IEC Joint Technical Committee (JTC) 1, Sub Committee (SC) 23: Digitally Recorded Media for Information Exchange and Retrieval. The American National Standards Institute (ANSI) serves as Secretariat of JTC 1, and the InterNational Committee for Information Technology Standards (INCITS) is the ANSI-accredited U.S. TAG Administrator to JTC 1/SC 23.
