34、arging equipment, existing microfilm can be used for: a. Rescaling drawings (.e., metric conversion) b. Scissors and paste-up drafting C. Refurbishing and updating old drawings d. Recreating lost originais. 2. l .7 Security, Protection Against Loss and Damage - Mi- crofilm copies shall be stored off
35、 premises or in a separate location in a secure area to protect valuable and irreplaceable information against loss by fire, theft, deterioration and mysterious disappearances. 2.2 The design of the microfilm systems should take into consideration that: a. Everyone involved in the system from design
36、 to the end user should understand the program, the system and the benefits to be achieved. b. It satisfies the present and future requirements. c. The system and operations will be as simple as possible. d. Working drawings submitted for microfilming will be processed without undue delay (should be
37、 con- sidered when developing procedures). e. Information on drawings and associated documents have been microfilmed will be available to users as soon as possible after the operations have been completed. 3. INDEXING OF MICROFI LM 3.1 1 After the drawings have been microfilmed, the micro- form shal
38、l be accurately identified and filed. Irnproper- ly identified or misfiled microfilm is almost impossible to find as all microfilm images tend to look alike. Therefore, it is essential to design a good indexing and retrieval system for the microform to be used to full ad vantage. 4. ROLL FILM 4.1 Ea

Toutes les personnes concernes par le systme, du concepteur lutilisateur, comprennent bien le programme, le systme et les avantages offerts. b. Le
43、systme satisfait aux exigences prsentes et futurs. c. Le systme et son exploitation seront aussi simpies que possible. d.
