By combining a slav
23、e card with an aperture card containing a microimage on 35 mm film, the information content is increased, handling of the aperture card is reduced, and it is possible to use the slave card for data processing. 1 Scope and field of application This standard specifies the aperture card for 35 mm micro
24、film and the column allocation and data entry of the control and identification characteristics for aerospace using card code A (see clause 4). 2 References ISO 1681:1973, Information processing Unpunched paper cards Specification.
