Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This method uses the translation method equivalent to ISO 18929.:2012 "image material wet processing silver rubber type black and white photographic reflective film dark Room storage specification ".

For ease of use, this standard has made the following editorial changes.

- the footnotes in 8.4.3 and 8.5.2 were deleted;

--- Change the note in Appendix B to page bets.

This standard is proposed by the China Petroleum and Chemical Industry Association.

This standard is nationalized by the National Standardization Technical Committee for Photographic Materials (SAC/TC102).

The drafting of this standard. China Lucky Group Co., Ltd., the National Photographic Materials Engineering Technology Research Center.

1 Scope

This standard has established a wet processing silver rubber black and white photographic reflective film darkroom storage specifications. Including all the weight of the silver rubber camera film.

This standard applies to wet processing of silver-based black and white photographic reflections, including chemical treatment (gold, selenium, sulfur or other) to improve the silver Image performance of the film, but also for the development of a clear combination of silver-type black and white photographic photographs, conventional washing, thiosulfate as a fixative.

This standard does not apply to directly processed black and white photographic film (undeveloped silver halide has not been removed after chemical treatment), or hot Black and white film. It is neither suitable for color and dye-type photographic film, nor is it applicable to other synthetic thiosulfates Fixing film.

This standard does not apply to those silver sulfide films that are converted to readily soluble by thiosulfate and are used for the exhibition of polyethylene as a support Pressure and attached reversal film.
