GB/T1773 Microfilming of samples and technical documents is divided into two parts: Part 1: Operation and inspection of 35 mm microfilm products Part 2: Quality standards and inspection of 15 mm microfilm cards Part 3: Photography of special and larger-scale images Part 4: Inspection procedures for microfilm images Part 5: General requirements Part 6: Quality criteria and control of 35 mm microfilm systems. CB/T 17739.3—2004www.bzxz.net This part is the third part of GBT17739. The amendment to this part is 15032723.2C0: Microfilm of technical drawings and other documents for office use Part 3: 35m microfilm opening card (English version). The difference from 1S03272-2:2J01 is: —This part is normative [use 4 GT/T6154.1—203. GT3/T5119.3-2053, GB/T6159.42003 are all international standards adopted in accordance with GB/T.19081983 and GB/T6159.222000 are equivalent to international standards; change the product share of 4.3 to \1.%, 1 general speed of the original 4,3,1.1,5.2,4.3.3 sections It is changed to 4.3.21.3.3.4.3.4 in sequence; according to the actual situation in my country, the "should be on the tape for a long time to protect the tape" in 1.3.3 was changed to "should be on the tape for a long time to protect the tape" in the next two years. The following code modification was also made to this part: "International standard" is changed to "this part", and the white before the standard is deleted: "Use small drum points", "Replace decimal points with commas", ". Appendix A of this part is a scientific appendix. This part is the same as the document imaging technology standardization committee (SAC) proposed and attributed to 1. The originating unit of this part is the National Document Imaging Technology Standardization Technical Committee, and the main initiators of this part are: the construction and consumption, and this part is secondary confidential. CR/T 17739.3—2004 Technical drawings and other technical documents may be photographed on microfilm cards, which may be cut and made into microfilms. 1 Microfilming of technical drawings and technical documents Part 3: 35 mm microfilm microfilm cards GB/T 17739.3—2004 (H/117739) This part specifies the technical characteristics of window cards with specified size and type. This type of card can be installed with a whole glue or microfilm. This part is applicable to adhesive window cards and envelope cards, including standard cards. This part is not applicable to size 2 Normative references The following references are used as the references of this part through the "T" section.

Figure 1 The size and position of the rectangular window hole on the card 4.3 Adhesive open-face cards 4.3.1 Overview The position is the same as the standard. .5.62±5.25 In this form, the adhesive tape is placed on the film through the hole of the card and the film is fixed at the hole. 4.3.2 Position of adhesive tape The approximate position of adhesive tape is shown in Figure 2. For front-side adhesive cards: For digital microfilm products, the adhesive tape should be placed on the front of the card, while for printed microfilm products, the adhesive tape should be placed on the back of the card. Unit is meter Direction station area: Card. Outside service. Base, esty u! Figure 2 Adhesive tape of adhesive structure 4.3.3 Adhesion of adhesive tape protective paper B/117739.3—2004 Before placing the microfilm on the opening card, a semi-transparent or opaque adhesive tape is pasted on the bottom of the opening card. The adhesive tape protective paper and the commercial hole adhesion test should meet the requirements of TSC6343:1981: to enable the protective paper to be removed by hand or by dynamic method. Student: The width of the adhesive section increases with the increase of the time, and the removal of the protective plate will become more difficult. 4.3.4 Thickening The thickness refers to the difference between the thickness of the card itself and the total thickness of the card after processing. According to the method of 5, the thickness should not exceed 1000 mm. 4.4 Envelope-type window card 4.4.1 As mentioned above, the surface of the envelope-type window card has a supporting sheet to form an envelope with a hole: the sheet is fixed in this envelope, and the supporting sheet should be made of a colorless and transparent thin film. 4.4.2 Position of the supporting sheet The position and size of the supporting sheet should be as shown in the figure. The single is m 2:, 55 base line. Note: The outer water side and vertical side of the wind increase are not fixed at the north of the station (center). Figure 3 Position and size of the envelope support piece 1≤19.63 GB/17739.3—2004 A.1 Shape and cut angle of angle (Informative Appendix) Window card. Angle and color The card should have one angle and a closed angle. From the card! If the angle is good, I can also be on the right. A.2 Unique microfilms shall be distinguished by printing the same colour or by printing the lower part with a colour mark. A.3 Colour mark The colour mark may be placed at any position on the card. If the microfilm is monochromatic, the most effective method is to print the colour mark at 6.5cm below the top of the card. The colour mark should be printed on the lower part of the card without any obvious reverse thickness. 4 [1] 1S(32721:1983 GB/T 1//33.3—20C4 Microphotography of technical drawings and other documents for laboratory use—Part 1: Procedure [2 IS0 $272 2-1133 Microphotography of technical drawings and other documents for laboratory use—Quality standards and controls for printing microfilms Part 2: 35 mm silver-gelatin type microfilms Tip: This standard content only shows part of the intercepted content of the complete standard.
