Standard contentSome standard content:
Chemical Industry Standard of the People's Republic of China
Photographic Chemicals
Subject Content and Scope of Application
Determination of Solubility of Couplers
This standard specifies the determination method of solubility of couplers. This standard is applicable to couplers used in the production of color films, color films and color photographic papers. 2 Method Summary
Dissolve a specified amount of coupler in a certain amount of solvent at room temperature and visually observe the quality of the solution. Instrument
Colorimetric tube: 15mL in volume, with ground stopper. 4
Determination MethodwwW.bzxz.Net
HG 2258 91
Weigh 1g of sample, accurate to 0.01g: place in a colorimetric tube, add 10mL of specified solvent, and gently shake the colorimetric tube to dissolve the sample. After the sample is completely dissolved, use a white object as a background to visually inspect the transparency of the solution under natural light (avoid direct sunlight). Additional notes:
This standard was proposed by the Science and Technology Department of the Ministry of Chemical Industry of the People's Republic of China. This standard is managed by the Photographic Chemicals Standardization Technical Management Unit of the Ministry of Chemical Industry. This standard was drafted by Beijing Chemical Plant. The main drafters of this standard are Guan Ruibao and Hu Suoqin. Approved by the Ministry of Chemical Industry of the People's Republic of China on December 28, 199114
The standard was approved by the exclusive website mma.bzsoso,cetn Various standards industry information is free to download and implemented on July 1, 1992
