Elastomer Compatibility Testing

Elastomer Compatibility Testing Overview

With the increasing industry demand, Savant Labs has added the capability to perform seal, (also called elastomer), compatibility testing. Seal compatibility testing is an important element of oil specifications to ensure that oil formulations are compatible with the gasket and sealing materials used in modern vehicles. This testing involves a meticulous process of cutting and soaking a standardized sample of the seal material in oil for a specified number of hours at a specified temperature. Once the soak phase is complete, the elastomers are tested for tensile strength, elongation, hardness, and volume swell and compared to the limits in the relevant specification. The data undergoes a rigorous quality review process and approved reference oils are also used. The reports are prepared according to the method guidelines.

  • API SN / ILSAC GF-5 and GF-6 specification testing by ASTM D7216         
  • API CK / FA-4 specification testing by ASTM D7216
  • GM dexos1™ seal compatibility tests
  • GM dexos2™ seal compatibility tests
  • ACEA seal compatibility by CEC L-112-16
