ISO 2240:2003

ISO 2240:2003 specifies the method for determining the ISO speed of colour reversal camera films producing continuous-tone pictorial images that are intended to be viewed on transparency illuminators or by projection as slides. It also applies to 8 mm and 16 mm motion-picture films used in non-professional applications. ISO 2240:2003 is not applicable to professional motion-picture films regardless of their applications.
