Organization: ASTM International
Publication Date: 1 January 2000
Status: inactive
Page Count: 9
ICS Code (Latex and raw rubber): 83.040.10
scope:

1.1 These infrared 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 65 mass % ethylene

8-13

Test Method B-For EPM and EPDM between 60 and 85 mass % ethylene, except for ethylene/propylene/1,4-hexadiene terpolymers

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/1,4-hexadiene terpolymers

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.
