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

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

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. Approved by the Ministry of Chemical Industry of the People’s Republic of China on May 23, 1997 and implemented on October 1, 1997
