scope:
This International Standard specifies a method for measuring the diffuse visual density of diazo films and projection visual density of vesicular films. It also determines density values of second generation microforms. This International Standard applies to second generation duplicates made from first generation microfilm of source documents and COM microforms. It does not apply to the printing density of the second generation of the diazo and vesicular duplicates.
