Specifies a method of determining the resolving power of a given camera, film and development combination used in a microcopying system or the resolution achieved in microcopies therefrom. It provides, for this purpose, a test pattern and a test chart (ISO test chart No. 2). The test chart should be used as part of a test target in the manner prescribed by each relevant International Standard covering various applications of microcopying. It does not specify a method of determining the resolving power of microfilm readers or print-producing equipment. It also specifies the manner in which the resolving power is to be quoted or defined.
