Standard Test Method for Determining Automotive Gear Oil Compatibility with Typical Oil Seal Elastomers

Importancia y uso:

5.1 There are several major causes of automotive lubricant-related seal failures. This test method addresses only those failures caused by excessive elastomer hardening, elongation loss, and volume swell and attempts to determine the likelihood that an oil might cause premature sealing system failures in field use. This test method may be used as a requirement of a performance specification, such as Specification D5760 and J2360.

5.2 Another major cause of seal failure is the formation of carbon, varnish, and sludge-like deposits on the seal lip. The deposit-forming characteristics of automotive gear oils are evaluated in Test Method D5704. That procedure is intended in part to evaluate the potential for oils to cause premature seal failure in field service.
