10、 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 been established has the right to be repre
11、sented 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 matters of electrotechnical standardization. International Standards are
12、 drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the 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
13、vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 14546 was prepared by Technical Committee ISO/TC 42, P

Spools shipped from point to point may have l
15、ateral runout as much as three times those indicated in this International Standard.INTERNATIONAL STANDARD ISO 14546:2000(E) ISO 2000 All rights reserved 1 Photography Aerial films and spools Dimensions 1 Scope This International Standard specifies dimensions for films, leaders and trailers, perfora
16、tions where applicable, and package marking for rolls of photographic film used in aerial applications. This International Standard also includes the sizes and dimensions of steel or aluminium spools for appropriate sizes of film. 2 Normative references The following normative documents contain prov
17、isions which, through reference in this text, constitute provisions of this International Standard. For dated 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 investiga
18、te the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.

24、tional Standard shall apply at the time of manufacture (except where specifically stated otherwise), when equilibrated and measured at atmospheric conditions of (23 2) Can d(50 5) % relative humidity, as specified in ISO 554. All measuring instrument calibrations shall be conducted at a temperature
25、of 20 C (as specified in ISO 1) and a relative humidity of 50 %. 5 Film dimensions Film dimensions shall be as shown in Figures 1 and 2 and as given in Tables 1 and 2, and apply to film at the time of cutting and perforating. Dimensions can be altered by a permanent ageing shrinkage and by temporary
26、 shrinkage or swelling due to changes in moisture content or temperature. Dimensionally stable films are required for aerial products, and any departure from the dimensions specified in this International Standard shall be no more than 0,2 % larger than the maximum tolerance, nor less than 0,3 % sma
27、ller than the minimum tolerance at the time of package opening. Dimension G (see Figure 2) is the offset of any given side-to-side perforation pair. 6 Film thickness The film thickness, including support, emulsion and any protective coatings, shall conform to the values given in Table 3. 7 Roll leng
28、ths Preferred roll lengths and tolerances shall conform to the values given in Table 4. Tolerances are 0,6 0 m.ISO 14546:2000(E) ISO 2000 All rights reserved 3 NOTE A tolerance of 10 is permissible on each of the 45 angles in the tapered end of the leader or trailer, but the two angles should be app
29、roximately equal.

However, some sizes of certain films may be supplied with either a spliced or int
33、egral leader and/or trailer. Integral leaders/trailers shall be cut to standard film widths as given in Table 1. Spliced leaders/trailers (dimension B, Figure 1) shall be as given in Table 5. The thickness of the splices, attaching the leader and the trailer to the film, shall not exceed 0,43 mm. Th

NOTE 1 Dimension B is measure
39、d at the keyway openings in the centre of the flange. For spools with flange thicknesses of 1,27 mm or less, dimension B is kept within its tolerance by embossing the centre of each flange outward. The embossed centres are not used with spools that have flanges 2,06 mm thick because the thicker meta
40、l fills out the space that is obtained by the embossing. Spools numbered 2 and 3 have embossed areas with outside diameters (dimension x) of 16,97 mm 0,40 mm and inside diameters (dimension x 1 ) of 14,27 mm 0,40 mm. Spools numbered 4, 5, 7, 8, 9, 18 and 19 have embossed areas with outside diameters
41、 of 25,40 mm 0,40 mm and inside diameters of 22,22 mm 0,40 mm. Spools numbered 14, 15, 16 and 17 have embossed areas with outside diameters of 26,97 mm 0,40 mm, and inside diameters of 25,10 mm 0,40 mm. Spools numbered 6, 9A, 10, 11, 12, 20 and 22 are not embossed. NOTE 2 For all spools listed in th
42、is International Standard, both flanges are identical. a The concentricity of the spindle hole (dimension J) and the flange periphery (dimension C) shall be within 0,762 mm of the total indicator reading. b The concentricity of the spindle hole (dimension J) and the core (dimension D) shall be withi
