It supersedes BS 5550-1.4.2:1978 which is withdrawn. This British Standard is published under the direction of the Consumer Products and Services Sector Board whose Technical Committee CPW/36 has the responsibility to: aid enquirers to understand the text; present to the responsible international committee any enquiries on interpretation, or proposals for change, and keep UK interests informed; monitor related international and European developments and promulgate them in the UK. NOTEInternational and European Standards, as well as overseas standards, are available from Customer Services, BSI, 389 Chiswick High Road, London W4 4AL. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the ISO title page, pages ii to iv, pages 1 and 2 and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

The work of developing International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. International Standard was ISO 3068 was developed by Technical Commitee ISO/TC 36, Cinematography. This second edition was submitted directly to the ISO Council, in accordance with clause 5.10.1 of part 1 of the Directives for the technical work of ISO. It cancels and replaces the first edition (i.e. ISO 3068:1975), which had been approved by the member bodies of the following countries: The member body of the following country had expressed disapproval of the document on technical grounds: USSR AustraliaGermany, F.R.Spain AustriaIndiaSweden BelgiumItalySwitzerland BulgariaJapanThailand CanadaNetherlandsUnited Kingdom CzechoslovakiaNew ZealandUSAa Egypt, Arab Rep. ofRomania FranceSouth Africa, Rep. of a Did not approve sub-clauses 4.2 and 4.3.

ISO 2966, Cinematography Motion-picture film 16/8S (1-3) and (1-4) Cutting and perforating dimensions. ISO 3027, Cinematography Magnetic stripes and recording head gaps for sound record on 8 mm Type S motion-picture prints Positions and width dimensions. 3 Film stock 3.1 The dimensions of the film stock shall conform to the specifications given in ISO 2966. 3.2 The dimensional features of the processed film after slitting shall conform to the requirements specified in ISO 1700. 4 Location and width of magnetic stripes 4.1 The location and width of the magnetic sound record stripes and balance stripes shall be as shown in the figures and given in the Table. 4.2 If the magnetic stripe increases the thickness of the film by more than 0,005 mm (0.000 2 in), a balance stripe shall be applied to effectively equalize the thickness at the two edges of the slit 8 mm film. The balance stripe shall essentially have the same thickness and shall have the same composition as the magnetic sound record stripe. 4.3 The thickness of the magnetic stripe and of the balance stripe shall not exceed 0,020 mm (0.000 8 in). 4.4 The stripes shall be applied to the side of the film which, when slit, will be towards the light source when used in a projection system arranged for direct front projection onto a reflection-type screen. 4.5 The location of the magnetic stripes on the processed film after slitting shall conform to that specified in ISO 3027.

If two stripes are used, the amount of separation between the stripes should be sufficient to permit slitting within the requirements of this International Standard without obtaining undesirable feather edges of magnetic material. The actual separation required should be determined by laboratory practice. NOTE 2In some instances, the metric dimensions in the Table are not exact conversions of the inch dimensions. The differences, however, are small and films made to either system of dimensions will, for all practical purposes be interchangeable. (The stripes are intended to be of equal width.)
