IS0 (the International Organization for Standardization) is a worldwide fed- eration of national standards bodies (IS0 member bodies). The work of preparing Internati

14、onal Standards is normally carried out through IS0 tech- nical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non- governmental, in liaison with

15、 ISO, also take part in the work. IS0 collabo- rates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulat- ed to the member bodies for voting. Publication as

16、 an International Standard requires approval by at least 75% of the member bodies casting a vote. International Standard IS0 8225 was prepared by Technical Committee ISO/TC 42, Photography. This second edition cancels and replaces the first edition (IS0 8225:1987), which has been technically revised

25、l Expert Eugene Ostroff iii Introduction Since 1930, great advances have been made in the use of photographic films for the preservation of records. The preservation of records on film by national, state and municipal governments, by banks, insurance com- panies, industry and other enterprises, has

26、been stimulated by recognition of the resultant economies in storage space, organization, accessibility and ease of reproduction. The cafe-keeping of pictorial film records having le- gal, scientific, industrial, medical, historical, military or other values has also become increasingly important. T

27、he use of film for records having long-term values necessitated the de- velopment of International Standards to specify the characteristics of film suitable for this purpose. IS0 10602 specifies the requirements for silver- gelatin films which are suitable for storage. This International Standard (f

28、or diazo film) and IS0 9718 (for vesicular film) give the requirements for photographic duplicate films suitable for storage. The term “archival film“ has been discontinued and the new concept of “life expectancy“ is introduced. Film life is classified by the LE or life ex- pectancy rating as define

29、d in this International Standard. For example, LE-100 represents film with a life expectancy of 100 years when stored under extended-term storage conditions specified in IS0 5466. Criteria for properties of LE-10 and LE-100 diazo films are based upon the dark-ageing stability of diazo images. Differ

30、ent dark incubation tests are specified for LE-10 and LE-100 films. All other property and processing requirements for medium and long-term diazo films are identical. It is recognized that diazo images may show density changes after ex- posure to light. However, this International Standard covers on

31、ly films used as storage copies, not as work copies (as defined in annex C). The light-fading requirements specified in this International Standard ensure satisfactory behaviour for storage copies which are not intended to be subjected to frequent light exposure. In addition to the characterization

32、of films with respect to their expected storage life, diazo films are also separated into two classes (A and B); these classes are dependent upon their intended use. Class A films are those which retain density in both the visual and actinic region (printing) after storage. Such films can be viewed

33、directly or reprinted onto ultra- violet (UV)-sensitive materials. However, some diazo films are not in- tended to be reprinted onto UV-sensitive materials. Such films require only visual capabilities after storage and are designated as Class B films. Ob- viously, both Class A and Class B films can

34、fall into the LE-10 and LE-100 categories. The requirements for Class A and Class B films are identical, with the exception of image-stability tests after dark-ageing and after light-fading. Everyone concerned with the preservation of records on photographic film should realize that specifying the c

35、hemical and physical characteristics of the material does not, by itself, assure satisfactory behaviour. It is also iv - ANSI IT9-5 9b 0724150 0533822 4TB essential to provide the correct storage temperature and humidity, and protection from the hazards of fire, water, light and certain atmospheric

36、pollutants. Conditions for the storage of record films are specified in IS0 5466 and IS0 10214.

37、his International cations for the stability Standard establishes specifi- of pOlyeSter-baSe safety film which has an ammonia-processed diazo photographic image. It covers photographic film intended for LE-1 O and LE-100 records. 1.2 This International Standard applies to photc- graphic film in which

38、 the image layer is a discrete layer attached to a transparent support. 1.3 It applies to roll film and sheet film. 1.4 This International Standard characterizes only the inherent keeping behaviour of the film. However, the suitability of a film record after extended storage depends on both the inhe

39、rent ageing characteristics of the film and the original image quality. The latter is discussed in annex B. 1.5 This International Standard applies only to diazo photographic film intended and used as LE-10 and LE-1 O0 storage copies. Storage copies should be stored in accordance with IS0 5466 and I

40、S0 10214. It does not apply to diazo film records intended and used as “work“ or “use“ copies (as discussed in an- nex Cl. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.

46、al medium: Recording material that can be expected to retain information for ever so that it can be retrieved without significant loss when prop erly stored. NOTE 1 There is, however, no such material and it is not a term to be. used in International Standards or system specifications. 3.2 life expe

47、ctancy (LE): Length of time that infor- mation is predicted to be retrievable in a system un- der extended-term storage conditions. NOTE 2 However, the actual useful life of film is very dependent upon the existing storage conditions (see IS0 5466 and IS0 10214). 3.3 LE designation: Rating for the “

48、life expectancy“ of recording materials and associated retrieval systems. The number following the LE sym- bol is a prediction of the minimum life expectancy, in years, for which information can be retrieved without significant loss when stored under extended-term storage conditions. NOTE 3 can be r

49、etrieved for at least 1 O0 years storage. For example, LE-1 O0 indicates that information 3.4 extended-term storage conditions: Storage conditions suitable for the preservation of recorded information having permanent value. 3.10 safety photographic film: Photographic film - which passes the ignition time test and burning time test as specified in IS0 543. 3.1 1 safety polytethylene terephthalate) base: Film base composed mainly of a polymer of ethylene glycol and terephthalic acid. 3.12 density: Degree of light absorption, reflection or scattering characteristics of a photogra
