The work of preparing International Sta
17、ndards 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. International organizations, governmental and non-governmental, in liaison with ISO, also
18、take part 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 voting. Publication as an Internation
19、al Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 6038 was prepared by Technical Committee ISO/TC 36, Cinematography. This second edition cancels and replaces the first edition (ISO 6038:1985), of which it constitutes a technical revision.

21、3(E) BSI 11-19991 1 Scope 1.1 This International Standard specifies the dimensions and locations of transverse cemented or welded overlap splices and butt splices on 70 mm, 65 mm, 35 mm and 16 mm motion-picture films and prints with magnetic or photographic sound records. 1.2 The following types are

34、1-1999 Table 5 Dimensions for all splices 2.6 The angle between the respective edges of the spliced films shall be 180 4. Thus, the spliced film shall be aligned to the extent that when one portion of the film is placed against a straight edge, the other portion does not deviate by more than 0,15 mm
35、 (0,006 in) per 13 cm (5 in). 3 General requirements 3.1 Butt and overlap tape splices shall be made with an optically clear, transparent tape. 3.2 All splices shall be capable of withstanding a tension which is at least 50 % greater than the gate tension of the projector for that film width. 3.3 Af
36、ter splicing, the perforation holes shall be maintained clear at all splices. 3.4 If the film to be spliced contains a photographic sound track and the modulation level at the point of the splice results in any individual bias line having a width of less than 0,05 mm, then the sound track should be
37、blooped or opaqued to avoid an objectionable audio crash. 4 Overlap splices 4.1 General 4.1.1 The overlap provides the desirable increase in stiffness at the splice to prevent sharp angular bending when the film goes around a small radius, as in the free loops above and below the projection aperture
38、. 4.1.2 When the overlap splice receives its mechanical strength from tape, it is usual not to scrape or otherwise remove the emulsion in the overlap area. 4.2 Recommendations for cemented overlap splices 4.2.1 The scraped area of one film end should be 0,03 mm to 0,08 mm (0,001 in to 0,003 in) narr
39、ower than the area covered by the overlapping film in order to prevent the appearance of a white line on the screen. 4.2.2 When splicing, the following recommendations should be observed: a) the cement should be applied to the full width of the splice; b) no air bubbles should be in the splice; c) c
40、ement excess should be removed, including that from the perforation holes. 4.2.3 If the film being spliced contains a magnetic stripe, the stripe should be removed from the base of the film falling on top of the mating piece. 4.2.4 Bevelled splices are recommended and scraping at an angle is preferr
41、ed because it provides a stronger splice. When film with magnetic stripes is spliced, it is recommended that the overlap should be oriented so that the trailing film drops on to the scanning head rather than jolts up on to it. 4.2.5 An overlap cement splice may be reinforced with splicing tape. 5 Bu
42、tt tape splices 5.1 Butt splices shall be made centrally on the frame line. 5.2 The clearance between the butted edges of the print at the splices shall not exceed 0,08 mm (0,003 in). Figure 5 For all film widths Dimensionmmin E max.0,330,013 G max.a0,050,002 a A difference in the lateral shrinkages
43、 of the two strips can make it impossible to maintain the tolerance. Shoulders formed by such misalignment should be bevelled.

44、ed to secure a butt splice shall not interfere with the film dimensions as specified in the International Standard for the particular film type. 5.4 The tape shall be wide enough to cover an area of at least half a frame on each side of the splice. It is preferred that the tape begins and ends on a
45、frame line so that the splice will be less visible. 5.5 The tape shall adhere uniformly to the film without corrugations or entrapped air bubbles. 5.6 For films with photographic sound records, the width of the tape used shall cover the full width of the film on both sides. For films with magnetic s
46、ound records, tape used on that side which does not carry the magnetic record and balancing stripes shall cover the full width of the film. Tape used on the side carrying the magnetic record shall not be placed in an area contacted by the magnetic heads. 5.7 Butt splices shall not be made with tape
47、on one side only since such films are not functional in projection. 5.8 Butt splices shall not be made with tape wrapped around the film since this interferes with guiding.
