FTM 3604 (FED-STD-701 Method 3604.2) Swelling of Synthetic Rubber by Aircraft Turbine Lubricants

Aircraft turbines contain seals, O-rings and other synthetic rubber pieces for connecting and sealing turbine components.  The synthetic rubber in these systems must be compatible with the fluid lubricants – they should absorb enough lubricant to achieve proper sealing, but not so much that the elastomers become less effective.  This test determines the amount that an elastomer swells in the presence of a test lubricant.  

Elastomers are weighed in air and water to determine the elastomer volume, submerged in the test fluid and heated to the test temperature for the test time.  Rubber components are then removed, cleaned and weighed again in both air and water to determine volume.  Reported is the percent swelling as calculated from the volume changes observed.
