标准范围

ISO 7004:2002规定了测定由胶片和胶片处理组成的工业射线照相系统在直接暴露于X射线和γ射线时的感光曲线形状、ISO速度、ISO平均梯度和ISO梯度G2和G4的方法。本国际标准中没有规定工业射线照相用荧光增强屏的胶片系统特性的测量。

ISO 7004:2002 specifies methods for determining sensitometric curve shape, ISO speed, ISO average gradient and ISO gradients G2 and G4 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.
