AIR FORCE MIL-M-9868E NOTICE 1 Document Information:
Title
MICROFILMING OF ENGINEERING DATA 35MM, REQUIREMENTS FOR
Command Standardization Office (COMSO)
Publication Date:
Jun 1, 1995
Scope:
The principal objective is to prescribe microfilming requirements and testing guidance for engineering data (see 6.4.1) source document filming and delivery of the filmed images to primary DoD repositories (see 3.1.2.2). MIL-M-9868 contractual requirements, Sections 3, 4, and 5, only cover Type I film (silver-halide). Type II (diazo) and Type III (vesicular) film requirements are not covered but, where appropriate, their relationships are discussed for clarification purposes. Additionally, source document imaging accomplished through the use of an engineering data Computer-output Microfilm (COM) device (see 3.3.1) is covered. Other COM devices are not covered.
DoD, other government agencies, civil agencies, contractors, engineering data suppliers (see 6.4.3), and any other users are cautioned that all requirements in the previous issue have been rewritten, some have been renumbered, combined, or deleted (see 6.8 and 6.9), and new requirements have been added. Requirements may be stratified throughout; so, it is necessary to read the entire specification (i.e., text, tables, figures, text footnotes, table footnotes, and figure footnotes). Stratification depends on the requirement being discussed. It must also be understood that the figures are representative; i.e., not drawn to scale.
User comments and recommendations for improvement are invited. Please use Standardization Document Improvement Proposal, DD Form 1426, when submitting your comments or recommendations. A sample form with the Preparing Activity (PA) information entered is located on page 45. If a DD Form 1426 is not available, a letter will suffice. Mail the DD Form 1426 or letter to: HQ AFMC/ENC, Wright-Patterson AFB OH 45433-5001.
a. MIL-M-9868 is one in a group of publications (i.e., military, Federal Government, non-government, and international) associated with engineering data source document microfilming. If additional noncontractual information is desired, several explanatory notes within Section 3 and Section 5 identify some of the associated publications.
b. MIL-M-9868 is a specification within the DoD EDRS (formerly designated EDMS) Standardization Area. Related information in other DoD standardization areas and Federal Supply Classes (FSCs) should not be overlooked (e.g., 6750, 6760, 8115, CMAN, DRPR, GDRQ, ILSS, IPSC, and PACK).
c. MIL-M-9868 requirements are intended to promote, not inhibit, philosophies of Total Quality Management (TQM) when a supplier (see 6.4.3) or any other user is tasked with implementing the requirements (see 3.4 and 4.2).
d. MIL-M-9868 reflects the present Defense Management Review (DMR) cost-effective standardization efforts (see 6.2). One of the efforts is to use Non-Government Standards (NASs) to the maximum extent when they are available and practical. The development, coordination (consensus), and adoption of the referenced NGSs (see 2.2) is a result of the Government-Industry Equal Partner process.
Throughout MIL-M-9868, the term "MIL-D" is used when referring to aperture, camera, copy, and image cards. These cards are a series of unique military 80-column tabulating cards with a "D" size aperture (i.e., DD Form 1562, Dual Purpose Engineering Document Card series). The "D" size aperture is a rectangular hole designed for 35mm microfilm. Commercial 80-column tabulating cards (popularly referred to as aperture cards) with either a C, D, E, or F size aperture are also available. However, the most commonly used commercial tabulating card is the card with a "D" size aperture. A commercial nontabulating A6 Aperture Card with either a C, D, E, or F size aperture is also available. The commercial A6 card size is metric (105mm width × 148mm length) but cards with a "D" size aperture are most commonly used.
Even though the width of the raw stock is 35mm, MIL-M-9868 is assigned an inch-pound designation. All functional microfilm dimensional requirements are inch-pound units. However, within the textual paragraphs, metric dimensions (i.e., mathematical equivalents) are shown in parentheses. It must be understood that these mathematical equivalents are only a soft conversion of the inch-pound dimensional requirements.
MIL-M-9868 by itself does not generate engineering data source documents. Therefore, an AMSC number is not applicable (see 6.3).
General microfilm classifications (i.e., type and class) are assigned in accordance with the film's photographic characteristics and functional usage. Within all classifications, Kind N (Negative) or Kind P (Positive) film is available. During processing, a clear line negative-appearing image is used with Kind N film and a opaque line positive-appearing image is used with Kind P film. For MIL-M-9868 purposes, generic expressions for the various classifications are shown in parenthesis. There are three general microfilm classifications:
a. Type I (silver-halide).
. Class 1 - Camera film, roll form or camera card. (First generation camera master.)
. Class 2 - Duplicating film, roll form. (Second generation noncamera silver duplicate master.)
. Class 3 - Duplicating film, roll form. (Third generation noncamera silver duplicate master.)
. Class 4 - Duplicating film, roll form. (Fourth generation noncamera silver duplicate master.)
b. Type II (diazo).1/
. Class 2 - Duplicating film. (Second generation distribution copy.)
. Class 3 - Duplicating film. (Third generation distribution copy.)
. Class 4 - Duplicating film. (Fourth generation distribution copy.)
c. Type III (vesicular).1/
. Class 2 - Duplicating film. (Second generation distribution copy.)
. Class 3 - Duplicating film. (Third generation distribution copy.)
. Class 4 - Duplicating film. (Fourth generation distribution copy.)
