本燃油滤清器试验方法的目的是提供通过台架试验方法评估燃油滤清器性能特性的标准化方法。当通过这些标准方法进行测试时，结合应用测试获得的数据，可用于建立过滤器的性能标准。为了保护发动机上的燃油供应设备，过滤要求的许多变化以及工作条件的变化使得很难指定有意义的“在用”性能标准，根据这些标准判断过滤器。通过使用这些标准试验方法，试验条件总是相同的，并且可以在高度置信的情况下对过滤器的性能进行比较。一旦知道特定应用的要求，可通过这些试验方法确定合适过滤器的性能标准，并可确定过滤器在工作中的性能充分性。 为了实现测试结果的最高可靠性，程序和设备必须符合本规范中规定的程序和设备。没有规定过滤器的最低性能要求，因为这是用户和制造商的责任。本文件仅适用于确定、解释和报告绩效特征的方法。单独的章节涵盖了评估过滤器的几种功能能力和机械性能所需的测试方法。每章都有推荐的材料、仪器和测试和评估程序。

The purpose of this fuel filter test method is to provide standardized methods for evaluating the performance characteristics of fuel filters by bench test methods. This, combined with data obtained from application tests, may be used to establish standards of performance for filters when tested by these standard methods. Many variations in requirements of filtration to protect fuel supply equipment on engines and variations in operating conditions make it difficult to specify meaningful "in-service" performance standards by which a filter may be judged. By the use of these standard test methods, test conditions are always the same, and comparisons of the performance of filters may be made with a high degree of confidence. Once the requirements of a particular application are known, performance standards for suitable filters may be established by these test methods, and adequacy of performance of filters for the job may be determined.In order to achieve the highest degree of reliability of test results, the procedures and equipment must conform to those specified in this code. No minimum performance requirements for filters have been specified, since these are the responsibility of the user and manufacturer. Only the methods of determining, interpreting and reporting performance characteristics are the proper province of this document.Separate chapters cover the test methods mecessary to evaluate the several functional capabilities and mechanical properties of the filter. Each chapter is complete with recommended materials, apparatus, and procedures for testing and evaluation.
