Specifies the characteristics of transparent A6 size microfiche, from both source documents and COM, meant for international interchange of information and for micropublishing. Applies to microfiche of uniform format with image arrangements of 49, 98, 270 and 420 frames and a single frame microfiche. Coverage includes definitions, cut mark, technical target, reduction ratio, symbols, and identification of the image frames.

This International Standard specifies the characteristics of transparent A6 size microfiche, from both source documents and COM, intended for international interchange of information and for micropublishing.

It is applicable to microfiche of uniform format with image arrangements of 49, 98, 270 and 420 frames and a single frame microfiche.

Depending on requirements, the microfiche may be negative-appearing or positive-appearing.

An annex specifies the characteristics of microfiche of uniform format with image arrangement of 30, 60, 63, 84, 208, 210 and 325 frames and microfiche of variable divisions of 2, 4, 8, 16, 32 and 64 frames used for certain applications.
