CB/808-1598 GB/T8UUJ-1388 GB/T17739,2-2C06 Each machine shall exchange technical samples and technical documents, and There is no ambiguity when the microfilm is printed. Microfilming technology is more convenient for the inspection, transmission, processing and storage of technical samples and technical documents. Microfilms should meet the precise requirements of size and quality so that they can be processed. If the original is sent strictly according to the size and shrinkage ratio of the microfilm, the quality requirements of the microfilm can be easily recognized. 1 Scope Microfilming of technical drawings and technical documents GB/T17739.2—2006 Part 2 35 Quality criteria and inspection of 35mm silver gelatin microforms This part of GBT17739 specifies the quality requirements and inspection methods for 35mm sawn gelatin black self-produced microfilms and technical documents. This part is applicable to the first generation, second generation and issuance of silver gelatin microforms of various technical drawings and technical documents. 2 Normative references The provisions of the following documents become the provisions of this part through reference to this part of GB/T17739: For any dated referenced document, all subsequent documents (excluding the contents of the period block) or versions thereof are not applicable to the technical part.
