GB/T 17293-2008Micrographics -- Planetary camera systems -- Test target for checking performance (English PDF)

Foreword

This revised standard adopts ISO 10550:1994 "Micrographics internet camera system --- --- Test target for checking performance." (In English).

This standard and ISO 10550:1994 as compared to the main technical differences are as follows.

--- Remove the ISO 3272-1. 1983, ISO 3272-2:1994, ISO 6199:1991 and ISO 9923:1994 and other four references file;

--- In GB/T 6161-2008 (ISO 3334:2006, IDT) instead of the ISO 3334. 1989;

--- To GB/T 18405-2008 (ISO 446:2005, IDT) instead of ISO 446:1991;

--- In GB/T 7973-2003 instead of the ISO 2469:1994.

This standard and ISO 10550:1994 compared to modify the main editorial as follows.

--- The "scope" of the discussion concerning the applicability of the chapter to read "for the production of 35mm roll film and aperture cards in the form of first generation microfiche System "product used;

--- Modify the "Normative references" introductory phrase chapter.

This standard replaces GB/T 17293-1998 "Micrographics inspection platform microfilm camera system performance using standard test board".

This standard and GB/T 17293-1998 compared to major technological changes are as follows.

--- Remove the GB/T 7517-1987, GB/T 8988-1988, GB/T 8989-1998, GB/T 8990-1998, GB/T 12356-1990, ISO 3272-1. 1983, ISO 6191:1991 and ISO 9923:1994 eight reference documents;

--- In GB/T 6161-2008 instead of GB/T 6161-1994;

--- To GB/T 18405-2008 instead of GB/T 18405-2001;

--- In GB/T 7973-2003 instead of the ISO 2469:1994.
