13、ISO3272-4:1994(E) BSI 04-2000 iii 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 int
14、erested 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 take part in the work. ISO collaborates closely with the International Electrotechnic
15、al 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 International Standard requires approval by at least75% of the member bodies casting a vote. Int
16、ernational Standard ISO3272-4was prepared by Technical Committee ISO/TC171, Micrographics and optical memories for document and image recording, storage and use. ISO3272consists of the following parts, under the general title Microfilming of technical drawings and other drawing office documents: Par
17、t 1: Operating procedures; Part 2: Quality criteria and control of35mm silver gelatin microfilms; Part 3: Aperture card for35mm microfilm; Part 4: Microfilming of drawings of special and exceptional elongated sizes; Part 5: Test procedures for duplicating diazo microfilm images in aperture cards; Pa

Easy exchanges of such documentation between organizations should be possib
19、le without ambiguities arising from the use of the information they contain. Microfilming enables the information contained in drawing office documents to be reduced to small dimensions thus facilitating survey, transport, handling and storage. Faithful reconstitution of a microform can only be acco
20、mplished readily if the microform satisfies precise requirements with respect to dimensions and quality. The quality requirements themselves can be fulfilled readily only if the original document complies with standards for the preparation of drawings for microfilming. 1 Scope This part of ISO3272es
21、tablishes general principles for microfilming drawings of special and exceptional elongated sizes specified in ISO5457. It is applicable to sequences of microfilmed multiple frame drawings, reduction ratios and frame overlap. 2 Normative references The following standards contain provisions which, t
22、hrough reference in this text, constitute provisions of this part of ISO 3272. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 3272 are encouraged to investigate the possibility of applying the
23、most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

27、s in the centre of the frame. It shall be recorded using the lowest reduction ratio that will allow the whole image to be accommodated within one frame. 5 Microfilming in sections 5.1 Centring marks When microfilming the drawings described in clause4 or drawings too large to be recorded in one frame
28、, centring marks shall be provided at the midpoint of the longer side of each section. Sequential sections shall overlap by at least 100 mm (see Figure 1). If originals have important information in the overlap area, the overlap shall be larger than 100 mm. The reduction ratio shall be selected from
29、 ISO 3272-1 to maximize the use of the frame area. 5.2 Positioning of the document on the camera table If a document requires rotation when microfilmed in sections, it shall be rotated through 90 in an anticlockwise direction. 5.3 Reduction ratio 1/30 5.3.1 Drawings or individual sheets of multishee
30、t drawings not more than 890 mm in width but more than 1 210 mm in length shall be microfilmed in sections, using multiple frames so that they will appear on the processed microfilm as shown in Figure 2. 5.3.2 Drawings or individual sheets of multisheet drawings more than 890 mm but not more than121
31、0 mm in width and more than 1210 mm in length shall be microfilmed in sections, using multiple frames so that they will appear on the processed microfilm as shown in Figure 3. 5.3.3 Drawings or individual sheets of multisheet drawings that are more than 1210 mm in width and more than 1 210 mm in len

33、ure 4), no section shall exceed 890 mm by 1 210 mm in size, and there shall be a minimum of 100 mm overlap between adjacent sections. To utilize a full frame for the final section, the overlap may be greater. 5.4 Reduction ratio 1/15 5.4.1 Drawings or individual sheets of multisheet drawings not mor
34、e than 440 mm in width but more than 600 mm in length shall be microfilmed in sections, using multiple frames so that they will appear on the processed microfilm as shown inFigure 2. 5.4.2 Drawings or individual sheets of multisheet drawings more than 440 mm but not more than 600 mm in width, and no

37、 Figure 2 to Figure 4), no section shall exceed 440 mm by 600 mm in size, and there shall be a minimum of 100 mm overlap between adjacent sections.

39、ure 2 to Figure 4 as well as by the engineering document and sheet number. The first frame of a multiframe series shall be numbered F1 and contain the title block. Succeeding frames shall be numbered F2, F3 etc. Identification characters used in microfilming shall be at least 25 mm in height, shall
40、be white on a dark background and shall be so positioned that they will appear in the lower part of the microfilm frame in an area clear of text. 6 Non-standard formats Other formats shall be treated as the smallest standard size that will accommodate the whole document.
