8、ved 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 in a subject for which
9、 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 Commission (IEC) on all mat
10、ters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standa
11、rd 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Internationa
12、l Standard ISO 5655 was prepared by Technical Committee ISO/TC 42, Photography. This third edition cancels and replaces the second edition (ISO 5655:1993), of which it constitutes a technical revision based upon ANSI/BAPM IT1.15-1994. Annex A of this International Standard is for information only.IN
13、TERNATIONAL STANDARD ISO 5655:2000(E) ISO 2000 All rights reserved 1 Photography Industrial radiographic films (roll and sheet) and metal intensifying screens Dimensions 1 Scope This International Standard specifies the preferred and recognized sizes and cutting dimensions of industrial radiographic
14、 roll and sheet films and metal intensifying screens. It also specifies package markings. The shaping of the corners of screens is not specified. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this Internati
15、onal Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents in
16、dicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 1:1975, Standard reference temperature for industrial length measurements. ISO 554:1976, Standard atmosph
17、eres for conditioning and/or testing Specifications. 3 Conditions for measurement of dimensions The dimensions and tolerances specified in this International Standard apply at the time of manufacture, measured under atmospheric conditions of (23 2) C and (50 5) % relative humidity, as specified in I
18、SO 554. Dimensions may be altered by a permanent shrinkage due to aging and by a temporary shrinkage or swell due to changes in moisture content or temperature. Normally, dimensionally stable polyester base is used for these film products, and there should be no departure from the specified dimensio
19、ns by more than 0,05 % greater than the maximum dimension and 0,08 % less than the minimum dimension at the time of opening the package. All measuring-instrument calibrations shall be conducted at a temperature of 20 C, as specified in ISO 1, and a relative humidity of 50 %. 4 Films in rolls 4.1 Wid

23、or rolls of width up to and including 100 mm nominal, the preferred nominal lengths shall be 90 m, 100 m, 150 m and 305 m. For rolls wider than 100 mm nominal, the preferred nominal length, exclusive of leaders and trailers, shall be 60 m. 5 Films in sheets 5.1 Dimensions 5.1.1 Preferred sizes Dimen
24、sions for preferred sizes shall conform to the values given in Table 3.ISO 5655:2000(E) ISO 2000 All rights reserved 3 5.1.2 Temporarily recognized sizes The sizes listed in Table 4 are becoming obsolete. Equipment manufacturers are advised to design future cassettes and screens for use with the pre
25、ferred sizes, so that the recognized sizes will be replaced by the preferred sizes. 5.1.3 Cutting and tolerance rules For the current sizes of sheets shown in Tables 3 and 4 and for new sizes, the cutting and tolerance rules shall be as follows. a) For the current sizes shown in Table 3 and for new
26、sizes (metric), the cutting and tolerance rules shall be as i n di ca tedinTa b l e5. b) For the sizes shown in Table 4, there is no general cutting rule and the tolerances on the cutting dimensions (aim values) shown in Table 4 shall be up to and including 11,4 cm nominal: 0,4 mm, and greater than
