为了控制、比较和提高感光材料产品的质量,必须研究并制订感光材料性能测定方法标准。多年来在化工部科技局标准处领导下,化工部第一胶片厂、化工部第二胶片厂、上海感光胶片厂、无锡胶片厂、辽源胶片广等作了大量的工作。在此基础上,化工部感光材料标准化技术归口单位、全国感光
In order to control, compare and improve the quality of photosensitive material products, we must study and formulate standards for the determination of photosensitive material properties. Over the years, under the leadership of the Standards Department of the Bureau of Science and Technology of the Ministry of Chemical Industry, a great deal of work has been done on the first film factory of the Ministry of Chemical Industry, the second film factory of the Ministry of Chemical Industry, the photographic film factory in Shanghai, the film factory in Wuxi and the Guangyuan Film factory in Liaoyuan. On this basis, the Ministry of Chemical Industry photosensitive material standardization focal point, the National Sensitivity
