Why should you use BS EN 10025‑4

BS 4975 specifies the design

Monitors included here are those with CRT

The measurements are to be made at an ambient temperature of (23 ± 5) °C on test specimens which have first been demagnetized

Photography. Industrial radiographic films. Determination of ISO speed, ISO average gradient and ISO gradients G2 and G4 when exposed to X- and gamma-radiation Ingestion-build-78747 Why should you use BS1 Scope This International Standard specifies methods for determining sensitometric curve shape, ISO speed, ISO average gradient and ISO gradientsG2 and G4 for industrial radiographic systems consisting of film and film processing when exposed directly to X rays and 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
