This handbook delineates the format and content criteria to be used in the preparation of test reports covering tests on systems, subsystems, equipment, components, and parts. This handbook is for guidance only. This handbook cannot be cited as a
12、requirement. If it is, the contractor does not have to comply. 1.2 Purpose. The purpose of this handbook is to foster uniformity in the portrayal of test results on items of material. It also provides for greater ease in the evaluation of the design suitability and performance capability of test ite
13、ms for use in new applications 2. APPLICABLE DOCUMENTS NOT APPLICABLE 3. DEFINITIONS 3.1 Appendixes. An appendix is defined as any portion of a report which is necessary to its completeness but which is separated from the balance of the report for convenience, or because it does not logically fall u
14、nder one of the preceding headings. 3.2 Exhibits. An exhibit is defined as any document which is furnished with a report but is not an integral portion thereof. It might consist of a separate test report on the same or similar item, or pertinent correspondence or vendor data sheets, or a memo report
15、ing important conversations. 3.3 Universal document number. That number which should identify each test report and will be furnished by the procuring activity when it is required. This number is to be assigned in addition to any existing originators report number. 4. GENERAL REQUIREMENTS 4.1 Basic d
16、ata. All test reports should contain all the collected data and all conclusions resulting therefrom for the test performed. 4.1.1 Test file. A test file should be established and maintained which should include original log sheets, diagrams such as, wiring, piping, schematics or block, as necessary
17、to completely describe the purpose, conduct and results of tests. Upon creating, this file should be given a permanent identifying number, which should appear on all subsequent documents associated with a particular test. 4.1.2 Notes. Notes of all incidents of the testing, such as adjustments made,
18、servicing performed, leaks, vibrations, and any other irregular functioning of the product and corrective measures taken, should be placed on log sheets and included in the test reports. 4.1.3 Use of supporting documents. When applicable data has been previously submitted as a result of a similar or
19、 related government-funded test, these should be quoted, excerpted, or used in whatever manner possible to direct, guide, support, substantiate, or shorten test reports. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-HDBK-831A 2 4.1.4 Authentica
20、tion. The test report should provide for the following signatures. 4.1.4.1 Responsible officer. The test report should be signed by a responsible officer of the contractors organization. 4.1.4.2 Government representative. A Government representative may witness the test and countersign the report. T
21、he latter signature should constitute verification of the data contained in the report, and should not necessarily indicate concurrence in the conclusion presented. 5. DETAIL REQUIREMENTS 5.1 Format. Test reports should be prepared in accordance with the following criteria. 5.2 Paper. Copies of docu
22、ments intended for technical data repositories or data exchange programs should be designated “data interchange submittal copies” and should be on white opaque paper. Complete text should be clear and sharp, of consistent high contrast, and preferably black-on-white. “Brownline” transparencies and “
23、Bluelines” should not be used for the above purposes. All other copies should be on carbon-backed vellum, pat, ozo-parchment, 14 pound bond or equivalent translucent material for reproduction purposes. 5.3 Pagination. 5.3.1 Page size. The size of each finished page should be 8 by 10 or 8 by 11 inche
24、s. The universal document number, page number and issue or revision date should be included on all sheets. Sketches, drawings and diagrams may exceed the 8 or 8 inch dimensions to form foldouts where the alternative would be extreme reduction in size of graphic material. 5.3.1.1 Margins. Adequate ma
25、rgins should be allowed so that the complete text can be easily read when the report is in bound form. 5.3.1.2 Numbering. Beginning with the first page, all pages of the test report should be numbered consecutively. The page number should be placed in the center of the bottom margin. 5.3.1.3 Binding
26、. The test report should be bound in such a manner that the pages can be removed without damage or mutilation to the pages. Full page tables, illustrations, etcetera, should be arranged so that the bottom of the table or illustration will be either at the bottom or at the right hand edge of the boun
27、d document. 5.4 Illustration. Where practical, illustrations should be provided when such would serve to clarify or otherwise aid in understanding the report. Illustrations should fit the required 8 by 10 or 8 by 11 inch dimensions of the report as noted in 5.3.1. Illustrations may include sketches,
28、 drawings, graphs, photographs, etcetera may be included in the main body of the report as applicable and should have dark work lines on light background. Drawings of “C” size should be avoided. However, inclusion of illustrations as appendixes under a proper group heading is preferred, provided ref
29、erences are indicated in the main body of the report. All photographic prints should be of high contrast and definition and should be page-size. When photographs are to be used as illustrations, 8 by 10 glossy prints should be included in the bond copy, and a positive transparency should be provided
30、 with the reproducible copy. In data interchange submittal copies, negatives are not acceptable in lieu of prints. 5.4.1 Color differentiation. Color differentiation should not be used for graphs, diagrams, etc. 5.5 Abbreviations. Abbreviations should be held to a minimum. Provided by IHSNot for Res
31、aleNo reproduction or networking permitted without license from IHS-,-,-MIL-HDBK-831A 3 5.6 Required elements. The report should contain the following elements in the degree of detail applicable to the size and complexity of the test item and the test performed, in the order specified. 5.6.1 Title p
32、age and cover. The cover is not mandatory, but if used should contain the information shown in figure 1, in approximately the same positions on the page. Cutouts may be used to allow the same information to show through from the title page shown in figure 2. Data interchange submittal copies should

41、y sheet, additional description should include the part manufacturers address and when available all of the following: size, type, rating, serial number(s), batch lot and date of manufacture. Vendor, trade association, federal stock, and military part number designations should be given when such nu
42、mbers exist, but none of these should be substituted for a complete description. Further description should include method of sample selection and whether tested item(s) are prototypes, pilot samples, from a model shop, or production items. When specimen(s) are components of a system, a brief descri
43、ption of the function within the system should be given.
