11、2001 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested i
12、n 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 take part in the work. ISO collaborates closely with the International Electrotechnical Commis
13、sion (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical
14、 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. Attention is drawn to the possibility that some of the elements of this part of ISO 3272 may be the subject of patent rights. I
15、SO 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 applications, Subcommittee SC 2, Application issues. This second edition cancels and replaces the first edition (ISO 3272-3:1975), which has bee
16、n technically revised. ISO 3272 consists of the following parts, under the general title Microfilming of technical drawings and other drawing office documents: Part 1: Operating procedures Part 2: Quality criteria and control of 35 mm silver gelatin microfilms Part 3: Aperture card for 35 mm microfi
17、lm Part 4: Microfilming of drawings of special and exceptional elongated sizes Part 5: Test procedures for diazo duplicating of microfilm images in aperture cards Part 6: Quality criteria and control of systems for enlargements from 35 mm microfilm Annex A of this part of ISO 3272 is for information

22、5 mm microfilm 1 Scope 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
23、not apply to A6 aperture cards. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 3272. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply.
24、However, parties to agreements based on this part of ISO 3272 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IE

42、perture cards, corner and colours A.1 Corner shape and corner cut Cards should have three round corners and one cut corner. It is preferred that, 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 microfor
43、m be identified by differently coloured or coloured striped cards. A.3 Colour stripes Colour stripes may be of any width and placed on the card 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
44、 colour stripe should be printed on the card and not produce any significant buildup on the card.
