自动变速器进气滤清器测试程序

[中文适用范围]： 本测试程序适用于汽车自动变速器中包含液压动力泵的液压泵吸滤器和过滤器。第5节中的各段包括各种测试和替代测试，这些测试并不适用于所有过滤器和应用，因此工程师必须为特定应用指定要执行的测试。这些测试程序仅用于评估过滤器的功能性能特征，耐久性不在本标准中评估。 过滤设计要求必须由工程师在过滤器装配图、适用的工程规范或类似于本推荐实践中找到的应用数据表上指定。参见图6。 压力回路过滤器，包括屏障和系统污染控制类型，不在本标准范围内。它们在设计和构造上与许多液压和润滑应用中使用的过滤器相似。压力过滤器的测试由第2节中列出的ISO和SAE标准涵盖。 [外文原描述]： This test procedure is intended to apply to hydraulic pump suction filters and strainers used in automotive automatic transmissions that include hydraulic power pumps. The various paragraphs of Section 5 include a variety of tests and alternative tests that are not applicable to all filters and applications, so the engineer must specify which tests are to be performed for a particular application. These test procedures are intended to evaluate filter functional performance characteristics only, durability is not evaluated under this standard.Filter design requirements must be specified by the engineer on the filter assembly drawing, an applicable engineering specification, or summarized on an application data sheet similar to that found in this recommended practice. See Figure 6 .Pressure circuit filters, both barrier and system contamination control types, are not covered under this standard. They are similar in design and construction to filters used in many hydraulic and lubricating applications. Testing for pressure filters are covered by the ISO and SAE StandardDetails listed under references in Section 2 .Cross Reference: 900561,930016,960535,AE-29,ASTMC778-12,ASTMMNL32,ISO11171,ISO11841-1,ISO11841-2,ISO11943,ISO12103/1,ISO1219-1,ISO16889,ISO3722,ISO3968,ISO4021,ISO4405,ISO4406,ISO5598,MIL-F-8815,MIL-H-5606,NFPAT3.10.8.7
