9、es). 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. International organizations, governmental and

10、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 rules given in the ISO/IEC Directives, P

11、art 3. The main task of technical committees is to prepare International Standards. 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 casti

12、ng a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 3272 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3272-3 was prepared by Technical Committee ISO/TC 171, Document imaging applic

13、ations, Subcommittee SC 2, Application issues. This second edition cancels and replaces the first edition (ISO 3272-3:1975), which has been technically revised. ISO 3272 consists of the following parts, under the general title Microfilming of technical drawings and other drawing office documents: Pa

17、This part of ISO 3272 specifies the technical characteristics of tab size aperture cards, data processing type, in which the aperture does or does not contain raw microfilm. It covers tape-type and jacket-type aperture cards, including camera cards. This part of ISO 3272 does not apply to A6 apertur

18、e cards. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 3272.

(See annex A.) 4.2 Aperture characteristics The dimensions

24、 and location of the aperture in the card shall be as indicated in Figure 1. Dimensions in millimetres Key 1 Aperture location NOTE For squareness of the buildup location to the card, the distance from the datum lines of the inner and outer horizontal and vertical edges of the buildup location shall

25、 not vary by more than 0,04 mm. aDatum line.

For tape-face cards, used for odd number generation microfilm, adhesive tape shall be attached to the face of the card; and for t

27、ape-back cards, used for even number generation microfilm, the adhesive tape shall be attached to the back of the card.

28、4.3.2 Adhesion of protection sheet to adhesive tape The adhesive on the tape shall be protected, before the microfilm is mounted, by a translucent sheet of release paper. Values for the maximum and minimum adhesion of the protection sheet, to facilitate the removal of the protection sheet manually o

29、r automatically, shall comply with the requirements of ISO 6343. NOTE As bond strength of the adhesive increases with contact time, so the ease of removal of the protection sheet decreases. ISO 3272-3:2001(E) 4 ISO 2001 All rights reserved4.3.3 Buildup thickness The difference between the thickness

30、of the aperture card alone and the total thickness of the card plus the adhesive tape after manufacture is the buildup thickness. The buildup thickness, measured in accordance with ISO 6342, shall not be greater than 5 m. 4.4 Jacket-type cards 4.4.1 General This type of aperture card holds the film

31、in place within the aperture by means of two support sheets attached to either side of the card, which form a pocket enclosing the aperture into which the film is placed. The support sheets shall be made of thin, optically clear polyester film. 4.4.2 Location of support sheets The dimensions and loc

32、ation of the support sheets shall be as indicated in Figure 3. Dimensions in millimetres NOTE For squareness of the buildup location to the card, the distance from the datum lines of the inner and outer horizontal and vertical edges of the buildup location shall not vary by more than 0,04 mm. aDatum

It is preferred th

34、at, when viewed from the face of the card, the cut is top left, but top right may be used. A.2 Colour It is recommended that different generations of microform be identified by differently coloured or coloured striped cards. A.3 Colour stripes Colour stripes may be of any width and placed on the car

35、d in any position. It is normal to use one colour. Most frequently used is a stripe along the top of the card which extends 6,5 mm down from the top edge. The colour stripe should be printed on the card and not produce any significant buildup on the card. ISO 3272-3:2001(E) 6 ISO 2001 All rights res
