本标准等效采用国际标准ISO7004照相-工业射线胶片-用X和γ射线曝光时,ISO感光度和平均斜率的测定中,规定了工业X线胶片感光度和平均斜率的测定方法。由于胶片的照相性能取决于射线的能量频谱分布,为此本标准规定了感光测定用标准射线源。胶片的照相结果还取决于显影加工过程。本标准不规定冲洗加工方法。因此,提供一种胶片的感光度和平均斜率数值时,要说明加工过程。

This standard is equivalent to the international standard ISO7004 photographic - industrial radiographic film - X and γ-ray exposure, the ISO sensitivity and the average slope of the determination of the provisions of the industrial X-ray film Sensitivity and the average slope of the determination. Since the film’s photographic performance depends on the energy spectrum of the radiation, this standard specifies the standard radiation source for photographic determination. Photographic results of the film also depend on the development process. This standard does not require processing methods. Therefore, to provide a film of the sensitivity and the average slope value, to explain the process.
