Scope:

This test method evaluates the compatibility of lubricating greases and fluids with coupons cut from standard elastomer sheets (Practice ASTM D 3182) or, optionally, from SAE Specification AMS 3217/2A (NBR-L) and AMS 3217/3A (CR) sheets.

Compatibility is evaluated by determining the changes in volume and Durometer A hardness that occur when elastomer coupons are totally immersed in a lubricant sample for 70 h at either 100 or 150 °C or as required by the lubricant specification.
