Abstract

Applies to the quality testing of microimages produced with a given micrographic system and allows to determine the potential legibility of documents recorded with that system. Annex A gives optional features for ISO test chart No. 1. This second edition cancels and replaces the first editions (ISO 435:1975 and ISO 446:1975), which have been merged into a single International Standard.
