11、ional Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has bee
12、n established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

Draft International Standards adopted by the technical committees are circulated to the member bodies for v

Only the effects of temperature and relative humidity on the media are considered.2 Purpose a
20、nd assumptions2.1 PurposeThe purpose of this International Standard is to establish a methodology for estimating the life expectancy of information stored on magneto-optical discs. This methodology provides a technically and statistically sound procedure for obtaining and evaluating accelerated test
21、 data.2.2 AssumptionsThe validity of the procedure defined by this International Standard relies on five assumptions: the failure mechanisms acting at the usage conditions are the same as those at the accelerated conditions; the linearity of the byte error rate (BER) estimated over the accelerated a
22、nd design conditions is valid; all failure mechanisms have been accounted for and appropriately modelled; failure caused by reversible effects such as surface dust is not included; failure from repairable parts such as external cartridge components is not included.3 Normative referencesThe following
