Standard Test Methods for Rubber—Determination of Ethylene Units in Ethylene-Propylene Copolymers (EPM) and in Ethylene-Propylene-Diene Terpolymers (EPDM) by Infrared SpectrometryMore info
1.1 These test methods cover the determination of the proportion of ethylene and propylene units in ethylene-propylene copolymers (EPM) and ethylene-propylenediene terpolymers (EPDM) over the range from 35 to 85 mass % ethylene. Four test methods are needed to encompass the variety of commercial polymers that contain additives or polymerized diene units that interfere with the various infrared peaks. Except when interferences are present, all four test methods should give similar results. The test methods appear in the following order:
1.1.1 Pressed Film Test Methods:
| Sections |
Test Method A—For EPM and EPDM between 35 and 70 mass % ethylene | 9 – 14 |
Test Method B—For EPM and EPDM between 60 and 85 mass % ethylene, except for ethylene/propylene/1,4-hexadiene terpolymers | 15 – 19 |
Test Method C—For all EPM and EPDM polymers between 35 and 85 mass % ethylene, using near infrared | 20 – 24 |
