The work of preparing International Standards
18、is normally carried out through ISO technical 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 ISO, also take pa
19、rt in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the
20、 technical committees are circulated 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 International Standard may be the subject of
21、patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 6148 was prepared by Technical Committee ISO/TC 42, Photography. This second edition cancels and replaces the first edition (ISO 6148:1993), of which it constitutes a technical
22、revision. Annex A of this International Standard is for information only. BSISO6148:2001ISO 8416:(1002)E ISO 1002 All rights rsedevre v Introduction International Standard ISO 6148 is based upon American National Standard ANSI/NAPM IT1.51-1997, which was a revision and redesignation of ANSI PH1.51-1
23、990 (Micrographic films), and incorporates information from ANSI PH 1.33 (Spools) and ANSI/AIIM MS 29 (Cores and spools). This International Standard acknowledges the practice of coating non-silver duplicating products on thin supports. BSISO6148:2001blank BSISO6148:2001INTENRATIONAL TSANDADR ISO 84
24、16:(1002)E ISO 1002 All rights rsedevre 1 Photography Micrographic films, spools and cores Dimensions 1 Scope This International Standard provides specifications for dimensions (thickness, width, length) of raw stock roll and sheet films for micrographic applications, including silver-gelatin, diazo
25、, and vesicular films, designed for document recording, computer output microfilming (COM), and duplicating or printing. These products require wet chemical, vapour, or heat processing after an image-forming exposure with actinic radiation; winding requirements for roll films; location and width of
26、the heading area for 105 mm wide rolls and sheets, and the width and thickness of the backing of that area; dimensions of spools, made either of metal or plastic, for 16 mm, 35 mm, and 105 mm microfilms; other spool materials are excluded, as well as spools that are integral components of cartridges
27、, cassettes or magazines of microfilm-recording equipment; dimensions of plastic and metal cores of 16 mm, 35 mm, and 105 mm widths. Dimensions for thin-walled paper-board cores with wall thickness of 7,6 mm or less, used routinely for sensitized duplicating material, are not included in this Intern
28、ational Standard. This International Standard is not applicable to processed-film dimensions in micrographic applications. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For date
29、d references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For unda
30、ted references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

32、signed 3.2 diazo film very low speed, high resolution, virtually grainless imaging material consisting mainly of a polyester support coated with a polymeric binder containing diazonium salts and a dye precursor which can couple in the presence of a base (e.g. ammonia vapour) to form an azo dye NOTE
33、Exposure to UV or other actinic radiation causes decomposition of the diazonium salt and destruction of its dye- forming capability. These properties are the basis of a direct-positive imaging system, widely used for producing copies of original silver microfilms or other masters with automatic prin
34、ter/processors that incorporate UV exposure and ammonia- developing components. 3.3 film flexible plastic material coated with a sensitized-gelatin layer (an emulsion) that can produce stable images upon light exposure followed by chemical processing NOTE The flexible plastic material is usually tra

36、frames 3.6 heading area area at the top of a microfiche reserved for the heading 3.7 heading area coating translucent coating applied to the whole surface of the heading area to provide a surface that accepts writing 3.8 microfiche microform in the shape of a rectangular sheet having one or more mic

38、ed scale and viewed at appropriate magnification with the aid of optical or electronic display devices 3.11 nominal size dimensions used in commerce for description of a product, as on product labels or in catalogues NOTE Nominal sizes are given only in metric values in new and newly revised standar

BSISO6148:2001ISO 8416:(1002)E ISO 1002 All rights rsedevre 3 3.12 preferred sizes standard industry sizes, determined by most frequent user demand (number of units) and product volume (square metres
40、) NOTE Designers of new equipment are encouraged to use preferred sizes whenever possible. 3.13 recognized sizes sizes which are in less demand than preferred sizes, but are used in sufficiently large amounts to justify identification in standards NOTE This category includes sizes whose popularity i
41、s diminishing or increasing. However, new equipment should not be designed for such sizes. 3.14 splice union of two pieces of film that are joined to form a single piece (usually found in roll format) 3.15 spool flanged, cylindrical core for roll film, with drive holes in each flange and axial holes
42、 for insertion of a spindle or pin 3.16 tolerances dimensions which define the boundaries of conformance of a product to the standard NOTE When tolerances are expressed as “ ”, the reference is to the aim dimension, not to the nominal. 3.17 vesicular film low-speed imaging material on a polyester su
43、pport, coated with a thermoplastic layer containing a UV-sensitive diazonium salt which, upon exposure to actinic radiation, results in decomposition of the diazonium salt and the formation of a nitrogen gas NOTE Brief post-exposure heating of the film softens the binder layer and permits localized
44、formation and trapping of tiny nitrogen gas bubbles, or vesicles. These scatter light and thereby can function as image elements under proper illumination and viewing conditions. To render such “bubble” images permanent, a second, uniform exposure is given and the resulting nitrogen gas is allowed t
