Film Viewer calibration full details are available in ASTM R 1742.

Dear Sabir,
A NDT film viewer box or station does NOT need any calibration. It needs to fullfil minimum requirements on light color, light intensity (measured in Candela/m*m and NOT in LUX!) and spatial light distributino by the used front glass. These minimum are defined in ISO 5580 and also very shortlyt in ASTM E 1742 (only light intensity). These requirerments have to be checks e.g. semi-annuially according to your QA system, but this is NOT a calibration.
Greetings
Uwe Z.
