10、tion Microfilm jackets are a means of arranging units of information in microfilm form into inter-related groups of units or chapters. This arrangement permits correction and addition of information without completely refilming the contents. Microfilm jackets are mainly used in active microfilm syst
11、ems but may serve as enclosures for storage of strips or single frames of microfilm. In order to help the user and manufacturer of microfilm equipment, standardization of the basic requirements for microfilm jackets has been necessary. Jackets are used in information systems composed of not only jac
12、kets but also jacket loaders, file cabinets, readers, reader-printers, and duplicators. When planning a system using more than one microform, appropriate International Standards should be consulted and suitable hardware should be chosen with the view to ensuring system compatibility. The microfilm j
13、acket consists of a support sheet and a thinner emulsion sheet affixed to the support sheet at a channel separation area to form the film channel into which microfilm can be inserted. The emulsion sheet is the contact printing surface. There are two types of jackets: those with registration holes an
14、d those without. Some jacket loading devices can handle either type of jacket while other loading devices can only handle one type of jacket. All jackets are, however, interchangeable in readers, duplicators, and enlargers. There are two versions of these types of jackets: one with the emulsion shee
15、t on the back and the other with the emulsion sheet on the front to accommodate a different generation of microfilm. Jackets with an emulsion sheet on the back are the more common. They are used for first generation or camera microfilm from a planetary camera or a rotary camera with an even number o
16、f mirrors. Microfilm is always inserted in the jacket so that the imaged side of the film is in contact with the emulsion sheet. When inserted in this way, the microfilm is right-reading from the support sheet side and the heading is facing the viewer and is also right reading. It is not recommended
17、 and not usual to put second generation microfilm in jackets. If, however, it is necessary, specific requirements for microfilming of the original documents should be followed. International Standard ISO 8127 defines the dimensions and other basic characteristics of the A6 size microfilm jackets. It
18、 is applicable to all microfilm jackets composed of a transparent support sheet and an emulsion sheet bonded together and divided in multiple channels to accommodate single or multiframe 16 mm or 35 mm microfilm, with a heading area incorporated. 1 Scope This part of ISO 8127 specifies the character
19、istics of five channel jackets for 16 mm microfilm. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 8127.

25、hannel arrangement The jacket shall contain five horizontal channels capable of accepting 16 mm microfilm. 4.3 Film channel width The minimum width of the film channel shall be 16,3 mm, thus permitting easy insertion of the 16 mm microfilm. 4.4 Insertion openings The insertion openings or slots shal
26、l be wider than the width of the film, and arranged symmetrical to the film channel centre line. The location and dimensions of the insertion openings are shown in Figure 1. When the heading is right-reading and the support sheet is facing the observer, the insertion openings shall be at the right-h
27、and end of jackets. NOTE The shape of the openings is optional. 2) To be published. 105 mm 148 mm 0,25 mm. 0 0,75BS ISO 8127-1:1989 BSI 15 May 2002 3 4.5 Jacket registration holes The registration holes are optional. When used, the diameter of the circular holes shall be 1,4 mm 0,03 mm and in the lo
28、cation shown in Figure 1. The hole further from the insertion openings may be circular or oblong. 4.6 Centre lines of film channels The spacing between the centre lines of the film channels and the spacing between the centre line of the top film channel and the centre line of the registration holes
29、(when used) or the bottom edge (when registration holes are not used) shall be as specified in Table 1. All centre lines shall be parallel to the bottom edge of the jacket. NOTE In jackets with registration holes, the 11,8 mm dimension is mandatory and the 84 mm dimension is optional. In jackets wit
30、hout registration holes, the 84 mm dimension is mandatory and there is no 11,8 mm dimension.

31、ding area shall be above the top film channel. Its minimum width, measured from the top of the jacket, shall be 8,5 mm. 4.8 Heading area coating (optional) Any coating or treatment shall be applied to the right reading face, and shall extend from the top of the support sheet to approximately the top
32、 of the first channel separator. It shall be translucent and shall accept mechanical or manual methods of titling without smudging or feathering. The coating shall transmit sufficient actinic radiant energy to facilitate duplication. 4.9 Colour stripe The colour stripe, when used, shall be 1,2 mm 0,
33、4 mm wide along the top edge of the heading area. 4.10 Emulsion sheet identification If any identification mark is used to indicate the emulsion sheet, it shall be located in the upper right-hand corner when the jacket is held with the longer side in a vertical position and the emulsion sheet toward
34、s the observer. The use of a rounded or straight corner cut or a notch for filing or indexing purposes is not precluded by this part of ISO 8127. 4.11 Code notch When a code notch is used, it shall be cut out of the top of the microfilm jacket to a depth of 4.12 Parallelism The channel separation ar
35、ea shall be parallel to the centre line of the two registration holes or to the bottom edge of the jacket within 0,2 mm over the entire length of the jacket. 4.13 Squareness Jackets shall have straight smooth edges which lie wholly within a rectangle having sides equal to the maximum length and widt

The total dimensions of the jacket shall be not less than the minimum dimensions. 4.14 Curl or bow When placed on a flat surface and measured by the method described in clause 5, the empty microfilm jacket shall not bow or curl in any direction by more than 6,5 mm above the surface. 4.

The material shall be in a
40、ccordance with the requirements of ISO 5466 and ISO 7830. The jacket material shall permit insertion and removal of the film strips without causing damage that would affect either the viewing or reproduction of the image and the jacket itself. 5 Methods of test 5.1 Curl or bow The curl of bow shall
41、be measured in accordance with method C, ISO 4330. Place an empty microfilm jacket convex side down on a flat surface for at least 6 h in an atmosphere of 23 C 2 C and (50 5) % relative humidity after which no part of the jacket shall be more than 6,5 mm above the surface. Measure the curl or bow by
42、 holding a scale perpendicular to the flat surface and as close as possible to where a curl or bow occurs. Measure the amount of curl or bow at eye level. 5.2 Optical clarity of jacket material Because of the loss of legibility due to the emulsion sheet, the legibility of a duplicate made from a fil
43、m inserted in a jacket cannot be identical to that of the same film obtained by direct contact. To control the legibility, make duplicates of a microfilm containing ISO test chart No. 1 or No. 2 in conformity with ISO 446 and ISO 3334. Make the first duplicate by direct contact between the original
44、microfilm and the print film. Make the second duplicate from the same original microfilm in a microfilm jacket. Compare both copies with the help of a microscope. The difference in legibility between the two duplicates shall not be more than one test chart pattern or number.BS ISO 8127-1:1989 6 BSI
