Standard Test Methods for Rubber - Determination of Ethylene Units in Ethylene-Propylene Copolymers (EPM) and in Ethylene-Propylene-Diene Terpolymers (EPDM) by Infrared Spectrometry
|Publication Date:||1 October 2017|
|ICS Code (Latex and raw rubber):||83.040.10|
These test methods cover the determination of the proportion of ethylene and propylene units in ethylenepropylene copolymers (EPM) and ethylene-propylenedi
Pressed Film Test Methods:
Test Method A-For EPM and EPDM between 35 and 70 mass % ethylene
Test Method B-For EPM and EPDM between 60 and 85 mass % ethylene, except for ethylene/propylene/1
Test Method C-For all EPM and EPDM polymers between 35 and 85 mass % ethylene, using near infrared
Cast Film Test Methods:
Test Method D-For all EPM and EPDM polymers between 35 and 85 mass % ethylene, except for ethylene/propylene/1
These test methods are not applicable to oil-extended EPDM unless the oil is first removed in accordance with Test Method D.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
