FTM-3603 (FED-STD Method 7913603.5) – Swelling of Rubber NBR-L (AMS3217/2D) @ 168 hours 

Synthetic rubbers may offer thermal and chemical stability superior to natural rubbers, making them attractive for use in o-rings, hoses, valves and other applications.  During use, the synthetic rubbers may be exposed to lubricating oils or greases.  If the lubricant is absorbed, it may cause the synthetic rubber to swell, aiding in the prevention of leaks.   If a large amount of lubricant is absorbed and the rubber swells excessively, the seal may soften, weaken and break. The lubricant might also cause the synthetic rubber to shrink, defeating the purpose of the seal.  This test determines the amount of swelling (or shrinking) that takes place in a synthetic rubber exposed to lubricants.  

The volume is determined for each synthetic rubber coupon.  The coupons are then immersed in the test grease or oil and stored at the test temperature for the test time.  The coupons are then removed, cleaned and the volume is again determined.  Reported is the average percentage change in the volume.  Optionally, hardness before and after exposure may also be made and reported.
