Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 13919-1992 "35mm Film Magnetic sound test strip technical specifications." This standard compared with GB/T 13919-1992, in addition to editorial changes outside the main technical differences are as follows. --- Modify the normative references; "Minimum duration of the signal," --- Table 1 was revised to "duration of the signal," and modify the value; --- Table 2 "duration of the signal" was changed to 30s; --- Table 3 in the "shortest duration of the signal" to "signal duration", and modify the frequency corresponding to the reference value; repair Changed "for all the frequencies of the maximum output level difference" value; modifying the frequency of 31.5Hz, 40Hz relatively short-circuiting of the magnetic flux Value. This standard uses redrafted modification method using ISO 4834-1997 (E) "movie does not include the coating of magnetic release prints, including magnetic vocal cords The basic technical characteristics of the test piece. " This Standard ISO 4834-1997 (E) technical differences are. --- The Normative references in international standards replaced by national and industry standards; --- Delete the contents of about 17.5mm and 16mm, 35mm test piece retained only a portion; --- Delete the contents of about 185 test strip, which is applicable to 60Hz frequency of the power supply; --- Deleted Table 3 the time constant characteristic. For ease of use, this standard also ISO 4834-1997 (E) made the following editorial changes. --- Changing the name of the standard; --- Remove the foreword and introduction; --- Remove the informative Appendix A and Appendix B; --- Removed some table note.
