1.1.1 Pressed Film Test Methods
| Sections | |
|
Test Method A-For EPM and EPDM between 35 and 65 mass % ethylene | 8-13 |
|
Test Method B-For EPM and EPDM between 60 and 85 mass % ethylene, except for ethylene/propylene/1 | 14-18 |
|
Test Method C-For all EPM and EPDM polymers between 35 and 85 mass % ethylene, using near infrared | 24-31 |
1.1.2 Cast Film Test Methods:
|
Test Method D-For all EPM and EPDM polymers between 35 and 85 mass % ethylene, except for ethylene/propylene/1 | 24-31 |
1.2 These test methods are not applicable to oil-extended EPDM unless the oil is first removed in accordance with Test Method D.
1.3 The values stated in SI units are to be regarded as the 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.
