Full Description

This standard specifies requirements for aperture cards, the mounting of 35 mm microfilm of technical drawings, camera cards, and copy cards used to reproduce 35 mm microfilm images from those cards.

This standard applies to the microcopying of all documents prepared by drawing offices, such as technical drawings, architect's plans, specifications, vocabularies, and parts lists. It deals with the requirements for the microcopying of such data onto single frames of 35 mm microfilm mounted individually in cards, bearing in mind their subsequent use for the interchange of information by reproduction, enlargement and viewing.
