The work of preparing International Standards i
4、s normally carried out through ISO technical committees. Esch 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, govern- mental and non-governmental, in liaison with ISO, also take p
5、art in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as Interna
6、tional Standards by the ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 486 was prepared by Technical Committee ISO/TC 36, Cinema tograph y. This third edition cancels and replaces the second ed

18、f the Standard.) A.l Uniformity of perforating The uniformity of pitch, hole size and margin (dimensions B, C and D, and EI are important variables affecting image steadiness. Variations in these dimensions within a roll from one Perforation to the next are more significant than variations from roll
19、 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 During its life, film tan shrink or swell due to changes in temperature or to loss or gain in moisture co
20、ntent. lt tan also shrink due to loss of solvent or plasticizer. These changes may result in changes in the dimensions. The Change is generally uniform through the roll. A.3 Definition of low-shrinkage film Low-shrinkage film is film which shrinks no more than 02 % from its original dimensions at th
21、e time of cutting and perforating, after the film has been a) kept in the manufacturers normal commercial packing for six months at recommended storage conditions; b) exposed; c) processed and dried as recommended by the manufacturer; d) stored in roll form, exposed to air, for a period not exceedin
22、g 30 days at 18 to 24 OC and 50 to 60 % relative humidity. A.4 Effect of humidity lt 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. 3 Copyright International Organization for Standardization Provided
