GB/T 12355-2008Micrographics - Splices of microfilm with image - Dimensions and Operational Constraints (English PDF)

Foreword

This standard replaces GB/T 12355-1990 "Micrographics microfilm images have connections." This standard compared with GB/T 12355-1990, major technological changes as follows:

--- Increased (Chapter 4) Chapter "Connection Type";

--- Added "different type of connection application" (Article 5.6);

--- The microfiche connecting edge inclination angle, "offset value should not exceed 2.65mm" (the original

2.4 and E values \u200b\u200bin the table) to "Offset value should not exceed 2.63mm" (now

5.4 and table E value);

--- The "this shift, on the same microfilm should not be cumulative with multiple connections" (formerly 2.4) read "This bias Shift on the same microfilm with multiple connections, the cumulative offset value should not exceed 2.63mm "(now 5.4). Appendix A of this standard is an informative annex. This Standard Document Imaging Technology by the National Standardization Technical Committee (SAC/TC86) and focal points. This standard was drafted. National Information Technology Standardization Technical Committee document the images of four clubs. The main drafters. Zhang Yang, Zhang increase. This standard replaces the standards previously issued as follows:

--- GB/T 12355-1990. Micrographics There are images of microfilm connection

1 Scope

GB/T 12355-2008 is the Chinese national standard on micrographics - splices of microfilm with image - dimensions and operational constraints, in the field of image technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 16 July 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2009. Classification: ICS 37.080, CCS A14. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies that the images have 16mm and 35mm roll microfilm connection requirements. This standard is applicable to the image of 16mm and 35mm roll microfilm connection.

4 Connection Type

This standard does not limit the type of connection. In practice, the film as a whole after the connection to use. Connecting materials and connection work Arts in Appendix A.

5 Microfilm connection

5.1 microfilm connecting portions Microfilm width of joints (see Figure 1 size A) beyond the width of the portion of the original film should not exceed 0.05mm. The two are connected Microfilm edge segment lateral displacement should not exceed 0.05mm (see Figure 1 and Table 1 D size), even if the two transverse shrinkage has microfilm When differences should be kept within the allowable range. In order to maintain smooth film edges, within the allowable range of displacement can be shifted to the edge Renovations.
