标准摘要
[中文适用范围]： 本国际标准规定了直接暴露于 X 射线和 γ 射线时，由胶片和胶片处理组成的工业射线照相系统的感光曲线形状、ISO 速度、ISO 平均梯度和 ISO 梯度 G2 和 64 的确定方法。 本国际标准未规定工业射线照相用荧光增感屏胶片系统特性的测量。 注：测量能量的单位在附录 A 中给出。 [外文原描述]： ISO 7004:2002 specifies methods for determining sensitometric curve shape, ISO speed, ISO average gradient and ISO gradients G 2 and G 4 for industrial radiographic systems consisting of film and film processing when exposed directly to X-rays and gamma-rays. The measurement of characteristics of film systems used in industrial radiography with fluorescent intensifying screens is not specified in this International Standard.
