8、dForeword ISO (the International 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

9、technical committee has been 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matter

10、s of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulat

11、ed to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible

12、 for identifying any or all such patent rights. ISO 18913 was prepared by Technical Committee ISO/TC 42, Photography. This second edition cancels and replaces the first edition (ISO 18913:2003), which has been technically revised. BS ISO 18913:2012ISO 18913:2012(E) ISO 2012 All rights reserved vIntr

14、 Standard establishes a vocabulary of terms and definitions used in relation to the permanence of imaging materials, related storage materials and digital storage media. In most cases these terms and definitions are generic and are applicable to the entire imaging industry. For terms and definitions

15、 specific to particular applications, industry standards are applicable. However, in some cases the definition of a term is still evolving and/or is used by different user groups in different ways. In these cases, a definition related to permanence of imaging materials work is given and a note to th
