本SAE标准旨在为车辆空气制动系统中使用的SAE J844空气制动管路的压缩管接头建立统一的性能标准和测试方法。 本文件还规定了拉伸和压力能力、循环温度下的振动耐久性、维修性和配件兼容性要求的最低资格。SAE J844中规定了适用于管材的具体测试和性能标准。 注:本性能标准中包含的测试值仅用于测试目的。有关环境和使用限制，请参考SAE J844。对于配件，SAE J246中包含了一种与SAE J844非金属管道一起使用的配件；然而，这并不旨在限制或排除符合本文件的其他配件设计的使用。

This SAE Standard is intended to establish uniform performance criteria and methods of testing compression tube fittings with SAE J844 air brake tubing as used in vehicular air brake systems. This document also establishes minimum qualifications for tensile and pressure capabilities, vibration durability under cyclic temperatures, serviceability, and fitting compatibility requirements. The specific tests and performance criteria applicable to the tubing are set forth in SAE J844. NOTE: The test values contained in this performance standard are for test purposes only. For environmental and usage limitations, refer to SAE J844. For fittings, a type of fitting for use with SAE J844 nonmetallic tubing is included in SAE J246; however, it is not intended to restrict or preclude the use of other designs of fittings that comply with this document.
