8、ational 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 represented on that committee. Inter
9、national 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 drafted in accordance with the
10、 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 vote. Attention is drawn to the
11、 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 732 was prepared by Technical Committee ISO/TC 42, Photography. This fourth edition c
12、ancels and replaces the third edition (ISO 732:1991 and ISO 1048:1991), of which it constitutes a combination and technical revision. A number of technical changes have been made to the figures that describe product dimensions, as well as to the specifications for paper width and thickness. Annex A
13、of this International Standard is for information only.INTERNATIONAL STANDARD ISO 732:2000(E) ISO 2000 All rights reserved 1 Photography 120-size and 220-size films Dimensions 1 Scope This International Standard provides specifications for dimensions of 120-size and 220-size films and of the spools
14、common to both, dimensions of the backing paper for 120-size film and the leader and trailer paper for 220-size film, as well as the placement of the paster tape used for attaching these papers to the films, minimum length of film required in front of the leading edge of the first image and behind t
15、he trailing edge of the last image, and markings on the backing paper and the trailer-paper for identification of the intended photofinishing process. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this Inte
16、rnational 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 investigate the possibility of applying the most recent editions of the normative documen
17、ts indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

18、mospheres for conditioning and/or testing Specifications. 3 Terms and definitions For the purposes of this International Standard, the following terms and definitions apply. 3.1 backing paper opaque, photographically inert paper, used with 120-size film and imprinted with frame numbers that are legi
19、ble through a camera window, providing protection against the danger of light exposure of the film to which it is attached NOTE The backing paper provides assistance at the beginning of the wind-up. 3.2 creep difference in location of the film end relative to the numbers on the backing paper, when w
20、ound on the spool, compared to their respective positions when laid out flat NOTE The difference exists because the backing paper, wound outside the film strip, assumes a curve of greater circumference than the film strip for each successive convolution.ISO 732:2000(E) 2 ISO 2000 All rights reserved
21、 3.3 exposure numbers consecutive numbers, or sets of numbers, printed on the outside of the backing paper away from the film NOTE The spacing of images on the film is established by sequential centring of these numbers in the window of older style cameras. 3.4 leader paper trailer paper shorter str
22、ips of paper attached to 220-size film (leader at the start of the film and trailer at the end of the film) for the purposes of light protection and winding, similar to the backing paper for 120-size film 3.5 spool cylindrical device that has a flange at each end, an axial hole for a pin or spindle,
23、 and on which the roll of film and paper is wound 4 Conditions for measurement of dimensions The dimensions and tolerances specified in this International Standard apply at the time of manufacture (except where specifically stated otherwise), measured under atmospheric conditions of (23 2) Can d( 5
24、0 5) % relative humidity, as specified in ISO 554. All measuring instrument calibrations should be conducted at a temperature of 20 C (as specified in ISO 1) and a relative humidity of 50 %. 5 Dimensions 5.1 120-size The dimensions for 120-size film and backing paper shall conform to the values show
25、n in Figure 1 and given in Table 1. 5.1.1 Thickness The following thickness values shall be maintained: backing paper: 0,06 mm minimum and 0,12 mm maximum; backing paper plus film: 0,24 mm 0,04 mm; backing paper plus film and paster tape: 0,40 mm 0,10 mm. 5.1.2 Backing paper width The maximum backin
26、g-paper width shall not exceed 62,90 mm. The minimum backing-paper width is at the manufacturers discretion, but should be sufficient to insure light- tightness of the undeveloped film.ISO 732:2000(E) ISO 2000 All rights reserved 3 Key: 1 Backing paper dimensions 6 Centreline of backing paper 2 Posi

The longer dimension of the paster tape (across the width of the film and leader or trailer paper) shall
38、extend at least to within 3 mm of both edges of the paper. 5.2.4 Register marks for automatic cameras A mark shall be imprinted at a specified distance ahead of the first image position on the 220-size leader paper. This mark, shown by dimension G in Figure 2, shall have an arrow head at the top and
39、 at the bottom. The space between the arrow heads may be filled in at the discretion of the manufacturer (with, for example, a word or aISO 732:2000(E) ISO 2000 All rights reserved 7 symbol), and indicates the starting position for automatic film-transport metering with most automatic cameras. A few
40、 automatic cameras require a different register mark (shown as a set of dashes, dimension E in Figure 2) closer to the start of the leader paper. This secondary marking is recognized, but the preferred position for the register mark is that indicated by dimension G. 5.3 Spool The dimensions of the s
41、pool used for both 120-size and 220-size roll films shall conform to the values shown in Figure 3 and given in Table 3. See A.4 of annex A for more information about the spool.

44、f exposed rolls 6.1 General A uniform and distinctive contrasting standard pattern shall appear along both edges of the trailing (exposed) end of the backing paper (120-size) or the trailer paper (220-size) of colour roll films in order to identify the intended photofinishing process. This shall be
45、of sufficient length to cover at least the entire outer lap of the paper. Films for a black-and-white process shall not have these standard patterns along the trailing edges. The pattern shall be additional to any other identifying printing included by the manufacturer. The manufacturers own marking
46、 shall be so arranged as not to obscure the identifying patterns. 6.2 Colour negative process The pattern for the colour negative process shall be a series of rectangles located along each slit edge. It is intended that there be sufficient rectangles to allow photofinishing personnel to distinguish
47、them easily before film processing. A manufacturer may remove some of the rectangles in order to substitute additional information such as the type of processing chemistry intended. Information regarding the appearance of these symbols is given in A.3 of annex A (see Figure A.1). 6.3 Colour reversal
48、 process The pattern for the colour reversal film process shall be a series of “plus” (+) symbols located along each slit edge. It is intended that there be sufficient “plus” symbols to allow photofinishing personnel to distinguish them easily before film processing. A manufacturer may remove some o
49、f the “plus” symbols in order to substitute additional information such as the type of processing chemistry intended. Information regarding the appearance of these symbols is given in A.3 of annex A (see Figure A.2). 6.4 Sealing bands 6.4.1 Colour roll films The sealing bands for securing colour roll films after exposure shall be coloured. This can be either printed on a coloured background or by use of coloured printing on a white background. 6.4.2 Black-and-white roll films In
