ICS37.100.99 Registration No. 412-1997 Chemical Industry Standard of the People's Republic of China HG/T2908—1997 idtISo6407:1992 Film dimensions for printing plates Photography-Film dimensions-Graphic arts1997-05-23Promulgated Ministry of Chemical Industry of the People's Republic of China Implementation on 1997-10-01 HG/ T 2908 —1997 This standard is equivalent to ISO6407:1992 "Photography-Film dimensions-Graphic arts". Appendix A of this standard is the standard appendix, and Appendix B and C are suggestive appendices. This standard was proposed by the Technical Supervision Department of the Ministry of Chemical Industry. This standard is under the jurisdiction of China Lucky Film Company, the technical unit responsible for photosensitive material standardization under the Ministry of Chemical Industry. This standard was drafted by China Lucky Film Company, the Second Film Factory of the Chemical Department of China Lucky Film Group, China Printing and Equipment Industry Association, and Gongyuan Photosensitive Material Corporation. Drafters of this standard: Wu Xiankai, Wang Lei, Zhang Boling, Huang Linwei, HG/T2908—1997 ISO Foreword ISO (International Organization for Standardization) is a worldwide federation of national standardization bodies (ISO member bodies). The work of formulating international standards is usually completed through ISO technical committees. Each member body interested in the disciplines for which technical committees have been established has the right to participate in the technical committees. Governmental and non-governmental international organizations can also participate in this work after contacting ISO. In all matters of electrotechnical standardization, ISO works closely with the International Electrotechnical Commission (IEC). Draft international standards confirmed by technical committees are circulated to member bodies for voting, and at least 75% of the members participating in the voting must agree to publish them as international standards. International Standard ISO6047 was developed by ISO/TC42 Technical Committee for Photography. Appendix A of this international standard is a standard appendix, and Appendix B and C are informative appendices. 1 Scope Chemical Industry Standard of the People's Republic of China Dimensions of Film for Printing Platemaking Photography-Film dimensions-Graphic artsHG / T 2908 -- 1997 idt Is0 6407 -- 1992 This standard specifies the nominal and target dimensions of sheet film and roll film used for printing platemaking and their cutting deviations. This standard also specifies the shape requirements of loose-leaf film, the core size of roll film, and the requirements for winding and packaging marks. This standard does not apply to document copying film. This standard uses metric units 2 Referenced Standards The provisions contained in the following standards constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, the versions shown are valid. All standards are subject to revision. Parties using this standard should investigate the possibility of using the latest versions of the following standards: ISO 1:1975 Standard reference temperatures for industrial measurements ISO 216:1975 A and B series of cut sizes for writing paper and certain types of printed matter 1S0554:1976 Specification for standard atmospheres for conditioning and/or testing 3 Conditions for dimensional measurement bzxZ.net The dimensions and deviations specified in this standard are applicable to film manufacturing when measured under atmospheric conditions specified in ISO 5541 (see Appendix B), with a temperature of (232°C) and a relative humidity of (50±5)%. 4 Fluorescent film 41 Dimensions 4.1.1 Recommended dimensions The nominal and national standard dimensions of the recommended dimensions shall comply with Table 1 and 2. The recommended dimensions are listed in Table 1. Table 2 lists the "A" dimensions converted from the writing paper series specified in 1S0216, which will be widely adopted. “A10 measurement system” is shown in Appendix A. 1) All instruments should be calibrated at 20°C (as specified in ISO1) and 50% relative humidity.
