This standard outlines the conditions that enhance the risk of hydrogen embrittlement of steel. It also defines the relief procedures required to minimize the risk of hydrogen embrittlement. SAE/USCAR-5 is intended to control the process.

This standard outlines the conditions that enhance the risk of hydrogen embrittlement of steel and define the relief procedures required to minimize the risk of hydrogen embrittlement. It is intended to control the process. 1.1 Hydrogen embrittlement of steel, which can cause brittle fractures under stress, occurs as a result of the absorption of hydrogen during cleaning, phosphate coating and plating processes. The susceptibility to hydrogen embrittlement increases with increasing stress (internal or externally applied stress) and increasing material strength. 1.2 Hardness readings in this specification are in Vickers scale. SAE J417 should be referred to for conversion to other scales. NOTE 1: All references to temperatures relate to part core temperature and not the indicated oven air temperature. Statistical data of verifications in temperature at the center of the oven load and oven temperature shall be established to develop the oven profile.

This specification defines the dimensional and performance requirements for aftermarket spin-on oil filters intended for use on gasoline engines. Filters meeting this specification may also be suitable for use on some diesel applications. Filters meeting these dimensional limits are intended to meet the oil filter fit and package requirements for engine and vehicle designs. Filters meeting the performance requirements are intended to maintain sufficient durability to support many of the OEM's recommended oil change intervals. Some OEM engines may require special filters for which this specification would not support.

This specification defines test methods and requirements for validation of solderless crimped connections. The purpose of this test is to simulate in the lab the stress seen in a typical life (15 years and 150000 miles) for a crimp connection and assure the crimp is mechanically strong and electrically stable. This specification was developed for use with stranded automotive copper wire. Only where specifically mentioned are other constructions or other core materials (aluminum, clad, steel core, etc.) applicable. This specification does not apply to wire types not mentioned, such as coaxial cable crimps, unless a USCAR-21 test is specifically referenced in the test specification for that wire type. This specification is based on accepted levels of environmental exposure for automotive applications.
