A AEROSPACE RECOMMENDED PRACTICE Issued 2001-03 Revised 2007-07 Superseding ARP5448 Plain Bearing Test Methods RATIONALE ARP5448 Revision A is a five year review and update of this specification. 1. SCOP
5、E This SAE Aerospace Recommended Practice (ARP) establishes methods for testing airframe plain bearings. The purpose of ARP5448 and its associated slash sheets is to document test methods commonly used to evaluate airframe bearings. These test methods may be referenced in specifications, part standa
6、rds, purchase orders, etc. when the test is deemed appropriate to the intended use of the bearing by the end user of the bearing. These test methods are not intended to encompass every conceivable requirement for an airframe bearing. The end user of the bearing must exercise engineering judgment to
7、determine the most appropriate standard and/or nonstandard tests for the application. 2. APPLICABLE DOCUMENTS The following publications form a part of this document to the extent specified herein. The latest issue of SAE publications shall apply. The applicable issue of other publications shall be

Each slash sheet document addresses a specific test method which is designated by a slash number commencing with number 1. A different
13、slash number is assigned to each test method. 3.2 Document Format Each test method is prepared as an individual document in the format of an Aerospace Recommended Practice. The basic document identifier, ARP5448, followed by a sequential slash number identifies the individual test method. The slash
14、number is identical to the number of the test method. See Figure 1 for an example: ARP5448 / 1 Slash number -Test Method No. 1, “Plain Bearing Radial Limit and Ultimate Load Tests” Document identifier assigned to the basic standard FIGURE 1 3.3 Method of Revision The individual test method is revise
15、d and issued independent of the other parts. Revisions are identified by a capital letter immediately following the document identifier dash number.

17、3.4 Selection of Tests Both the application requirements and the bearing characteristics that affect its performance in the application should be considered when selecting tests. After these essential properties have been determined, the appropriate test should be selected and specified for each pro
18、perty. Care should be taken to specify only those tests that are needed. 3.5 3.5 Method of Reference Test methods shall be referenced by specifying: a. The test method number with the applicable slash sheet number. For example: “The bearing shall be tested in accordance with ARP5448/5“ to specify th
19、e current version. b. Test criteria or property values required. 4. DETAIL REQUIREMENTS Detail requirements shall be incorporated in the individual test method.
