ASTM Specifications (9)
Most quality manufacturers of Orings specify the physical properties of their product through ASTM (American Society of Testing and Materials) and/or SAE (Society of Automotive Engineers) designations. The purpose of doing so is to provide a standardized method of calling-out the required physical properties of a rubber product, based primarily on its Type (Heat Resistance) and Class (Oil Resistance). An example of an ASTM Specification for a general purpose, sulfur-cured, 70 Duro Nitrile may be:
ASTM D2000-99 M2BG714 B14 EA14 EF11 EF21 EO34 Z1 |
