6、UAIIM Improperly spliced microfilm can result in numerous difficulties when making subsequent microfilm copies or when used in readers and reader-printers. It is the in- tent of this standard to prevent splice related problems by establishing adequate splice requirements. The splices described in th

7、is standard may not be suitable for use with automated retrieval equipment. Table 1, Dimensions - figures 1 through 4, is included to accompany the figures in this standard. Table 1 lists the dimensions that are used in figures 1, Fim width at splice; figure 2, Over- lap splice; figure 3, Butt-splic

8、e; and figure 4, Enlarge- ment of alignment dimensions. This standard is a revision of ANSI/AIIM MS18-1987, Splices for Imaged Film-Dimensions and Operational Constraints. Suggestions for improvements of this standard are wel- come. They should be sent to the Chair, AIIM Standards Board, Association

Samples shall be conditioned to this environment for 24 hours before testing. 5.6 Qpes of splices In most cases, heat-weld splices are recommended for films with triacetate base and ultrasonic splices for films wit

12、h polyester base. If cemented splices are used, the cement shall contain no acetic acid or other chemicals that will be injurious to the long-term keeping qualities of the film. Cellophane tape and tape of the pressure- sensitive type shaii not be used for making splices unless the adhesive is formu

13、lated so that it is not injurious to the long-term keeping qualities of the film, and the adhesive will not migrate from under the splice. 6 Number of splices per roll For best results in viewing and duplicating equipment, it is recommended that there be no more than six splices within the image are

14、a of the film. This is especially important with preservation microfilm.

15、s for Imaged Microfilm - Dimensions and Operational Constraints.) 1. If cemented splices are used, the cement shall not contain any chemicals that will be injurious to the long-term keeping qualities of the film or film images. 2. If tape is used, the tape should be of high transparency if placed ov

16、er an imaged area. Opaque tape can be also used if it is placed on a non-imaged area. There should be no adhesive oozing, migration or bleeding under the conditions of use, such as provided by a hard acryIic adhesive. The tape should be of material that will not shrink with age or environmental cond

17、itions - thus exposing the adhesive. There should be no air bubbles or foreign particles under the splice. The edges of the tapes must firmly adhere to the film. Avoid overlapping of the ends of the tape. To ensure a strong splice, it is recommended to place the tape on both sides of the film. See s

18、ection 5.2, Film thickness at the splice. 3. If tape is used to repair a section of film which is damaged (torn) in an imaged area, it may be necessary, if duplicates may be required, to limit the tape to the base side only. If tape is placed on the emulsion side of the film, the duplicate image may

19、 be out of focus. 4. Splicing shall be done so as not to impair the integrity of images nor interfere with blip or other coding methods. Whenever possible, at least 25.0mm (0.98 inch) of space shall be allowed between an image and the splice. 5. Splicers must be maintained in good working order. It

20、is advisable to test the strength of the splices each day using the same film stock as that being employed for the film being spliced. 3 AIIM MS1B 92 m LO12348 0500235 T31 m ANSI/AIIM MS18-1992 O by Association for Information and Image Management 1100 Wayne Avenue, Suite 1100 Silver Spring, MD 20910-5699 Tel: 301/587-8202 Fax: 301/587-2711 I SB N-0-89258-248-0 Printed in the United States of America
