This standard specifies the minimum test target elements and their criteria to be used in determining the uniformity of illumination on the copyboard of a 35mm planetary camera. The layout of the test target and the procedure to obtain a uniform density of microfilm images from a planetary camera are established to assist in the achievement of high-quality, first-generation silver-gelatin microfilm of engineering drawings.
