The selection of fasteners in the design and c
8、onstruction phase of weapons systems and equipment and the analysis of fasteners used therein for parameters, such as suitability, standardization, and simplification requires the evaluation and correlation of test data and critefia. In evaluating these fbnctions, it has become increasingly evhent t
9、hat the data and criteria received from prime contractors, fastener producers, private laboratories, military documents, and military laboratories cannot be adequately correlated. The chief reason for this is the absence of unified standards prescribing test methods, procedures, fixtures, data analy
10、sis, and data presentation. This disparity encourages and often requires duplication of testing and reduces reliability of weapons systems and equipments, thereby impairing operations involving engineering control, design maintenance, quality assurance, standardization, and logistics simplification.
11、 To correct this situation it was established that a unified set of test methods and procedures is required to serve as a basic engineering tool for obtaining and presenting engineering data. As a result, this document was developed and prepared to satisQ this vital need. This standard delineates st
12、andard test methods, procedures, conditions, fixtures, and methods of recording, analyzing and presenting test data. The purpose of the resulting test data is to determine the capability of fasteners to withstand the various environmental and mechanical conditions encountered when used in military w
13、eapons systems. 2. Benefits. Many benefits are to be expected by unified standard tests for fasteners. The following is a list of benefits that can be expected to accrue from using this standard. a. Availability of testing techniques and criteria qecessary for the design and development of increasin
14、gly superior structural fasteners. In the past, when a new fastener was needed to solve a problem, the necessary test procedures had to be developed and written; also, the necessary fixtures had to be designed. This always imposed delays, additional expenses, variations in test methods and in test r
15、esults. b. Increasing incidences of correlation among fadtener test data and design engineering techniques and design criteria for weapons systems and equipments. As new systems are designed to achieve higher performance for a given volume and mass of material, it is essential that design data for s
16、tructural joints (a large portion of which is obtained by testing fasteners) maintain a i close correlation with engineering techniques and design criteria. Where weight is of importance, such as in aircraft structures, such close correlation will provide a substantial reduction in weight. SHEET 2 A

Reduction in the time and effort required for the development of procurement specifications for fasteners by having a series of standard tests

Elimination of duplication in the development of test methods and documents by individual fastener producers, Government contractors, and military activities. f Elimination of duplication of effort in research and evaluation due to lack of unified standard test methods. When test meth
21、ods are not standard, results cannot be correlated; therefore, producers, prime contractors, and military activities will not accept each others results and will duplicate research, development, and evaluation work. g. For logistics simplification, fastener attributes must be reduced to a common den
22、ominator so that variation in type can be compared. Data and the presentation thereof, by means of this standard, will be provided in such form that various types and variations in types of fasteners may be compared to determine their degree of interchangeability, substitutability, and replaceabilit
23、y. h. Time and effort required to reach agreement in regard to specific engineering changes will be reduced by providing unified standard tests for use in evaluating new fasteners. i.
