9、wide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on t
10、hat committee. International organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted
11、 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. International Standard IS0 69 was prepared by Technical Committee ISOlTC 36, Cinematography. This third editio
12、n cancels and replaces the second edition (IS0 69:1990), clauses 2, A.2 and A.6 of which have been technically revised. Annex A of this International Standard is for information only. 1 Scope This International Standard specifies the cutting and perforating dimensions for 16 mm motion-picture and ma
13、gnetic films with one or two rows of perforations for the following two categories: a) b) 16 mm motion-picture and magnetic films; manufacturer-designated 16 mm professional motion-picture camera films with tighter tolerances. This International Standard applies to safety raw stock film as described
14、 in IS0 543. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements
15、based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

27、1 For film perforated along one edge, the edge adjacent to the perforation is the reference edge. 4.2 For film perforated along two edges, the reference edge shall be identified by the winding of the film. With the film wound emulsion-in, and the roll of film unwinding downwards toward the observer,
28、 the reference edge is along the right-hand side of the film (see figure 5). 4.3 The sequential edge numbers (key numbers or footage numbers) are exposed by the film manufacturer along the reference edge of the film.

29、rence edge Reference edge Annex A (informative) Explanatory notes A.l Uniformity of perforating The uniformity of pitch, hole size and margin (dimensions B or B, C and U, and E) are important variables affecting image steadiness. Variations in these dimensions within a roll, from one perforation to
30、the next, are more significant than variations from roll to roll. Actually, it is the maximum variation from one perforation to the next within any small group of consecutive perforations that is the most important variable. A.2 Dimensional stability The user is reminded that film dimensions can cha
31、nge due to moisture, temperature, and strain effect, or, in some film-base materials, due to solvent or plasticizer loss. These changes are generally uniform throughout the roll, A.3 Definition of low-shrinkage film Low-shrinkage film is film which shrinks no more than 0,2 % from its original dimens
32、ions at the time of cutting and perforating, after the film has been a) b) exposed; c) d) kept in the manufacturers normal commercial packing for six months at recommended storage conditions; processed and dried as recommended by the manufacturer; stored in roll form, exposed to air, for a period no
33、t to exceed 30 d at 18 “C to 24 “C and 50 % to 60 % relative humidity. The film is measured under the same conditions of temperature and humidity as defined in 3.1. Page 6 IS0 69 : 1998 A.4 Choice of longitudinal pitch The choice of different pitch (B: long pitch and 8: short pitch), for original an
34、d print motion-picture films, depends on the necessity of printing and the type of printer used. In the most common type of printer, the original and print films move continuously over a printing sprocket. Consequently, the original film must be shorter in pitch than the print film in the approximat
35、e proportion of the thickness of the film to the radius of curvature of the printing sprocket. With current printing sprocket designs, the value for this pitch differential is 0,3 Yo, with experience showing that a tolerance of f 0,l YO is acceptable. With “low-shrinkage” film base, it is common man
36、ufacturing practice to set the aim for the pitch of original films at a value of 0,2 Yo shorter than that of the films on which they will be printed. The additional shrinkage that occurs in the original film, because of processing and ageing before printing, should result in the desired 0,3 % k 0,l
37、% shorter pitch. A.5 Effect of humidity It is the common tendency of the film to expand when exposed to high relative humidity. Allowance should be made for this factor in equipment design. A.6 Equipment design In order to achieve optimum cancellation of dimensional variables, it is preferable that
38、equipment (e.g. cameras, printers, telecines and projectors) position the film laterally using the reference edge. Optimum vertical steadiness results when the same perforation (with respect to the image) is used for vertical positioning in all equipment, and the +3 perforation is recommended as shown in figure A.l (see IS0 251 994, Cinematography - Camera usage of 16 mm motion-picture film - Specifications).
