    Abstract - (Show below) - (Hide below)

    Specifies methods for measuring the ISO average gradient of industrial radiographic film when exposed directly to X and y radiation. Coverage includes: film holders, scattered radiation, film holders, modulation, and densitometry. Also gives detailed tables.

    Scope - (Show below) - (Hide below)

    This International Standard 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 γ-rays. The measurement of characteristics of film systems used in industrial radiography with fluorescent intensifying screens is not specified in this International Standard.

    NOTE Units of measured energy are given for information in annex A.
