Photography — Colour reversal camera films — Determination of ISO speed

Cancels and replaces the first edition (1982). Gives 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. Also applies to 8 mm and 16 mm motion-picture films used in non-professional applications. Does not apply to professional motion-picture films regardless of their applications.
