现提供SAE J1401标准全内容;SAE J1401是关于用于道路汽车液压系统的液压制动软管的测试标准，SAE J1401同时也指出了区分各大生产厂商的标准方法。本版本标准为J1401-2003，后续数字指定的是最近标准修改被采用的年份。SAE J1401标准英文原文1.ScopeThis SAE Standard specifies the performance tests and requirements for hydraulic brake hose assemblies used in the hydraulic braking system of a road vehicle. It also specifies the methods used for identification of the hose manufacturer. This document applies to brake hose assemblies made of a hose fabricated from yarn and natural or synthetic elastomers and assembled with metal end fittings for use with nonpetroleum-base brake fluids as specified in SAE J1703 and SAE J1705.The nominal internal diameter of the brake hose shall fall within one of the following values:a. 3.5 mm or less (1/8 in or less)b. 4 to 5 mm (3/16 in)2.References2.1 Applicable Publications—The following publications form a part of this specification to the extent specified herein. Unless otherwise indicated, the latest issue of SAE publications shall apply.2.1.1 SAE PUBLICATIONS—Available from SAE, 400 Commonwealth Drive, Warrendale, PA 15096-0001.

Definitions3.1 Brake Hose Assembly—A brake hose equipped with end fittings for use in a brake system.3.2 Brake Hose—A flexible conduit manufactured for use in a brake system to transmit and contain the fluid pressure medium used to apply force to the vehicle"s brakes.3.3 Brake Hose End Fitting—A coupling, other than a clamp, designed for attachment to the end of a brake hose.3.4 Permanently Attached End Fitting—A coupling designed for permanent attachment to the ends of a brake hose by crimping or swaging.3.5 Free Length—The linear measurement of brake hose exposed between the end fittings of a brake hose assembly while maintained in a straight position.3.6 Leaks, Burst—The loss of test fluid from the brake hose assembly other than by the designed inlet(s) and outlet(s).3.7 Cracking—The interruption of a surface due to environment and/or stress.3.8 Hose Internal Diameter—A dimensional description of the nominal inside diameter that is printed on the hose cover. This dimension is to be used to calculate the gage size for the constriction test.EXAMPLE—3 mm4. Performance TestsPerformance tests for hydraulic brake hose assemblies include all of the tests listed in Table 1. These tests shall be conducted on each I.D. size and type1 from each hose manufacturer. A change in hose construction, that is, a change in material or a change in the manufacturing method, shall require a complete performance test. Accordingly, each coupler shall conduct the perfor
