1.1These 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:
1.1.1Pressed 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 |
1.1.2Cast Film Test Methods:
| Test Method D—For all EPM and EPDM polymers between 35 and 85 mass % ethylene, except for ethylene/propylene/1,4-hexadiene terpolymers | 25 – 32 |
1.2These test methods are not applicable to oil-extended EPDM unless the oil is first removed in accordance with Test Method D.
1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
