1.1This test method covers the determination of molecular weight distributions and molecular weight averages of linear polyolefins by high temperature gel permeation chromatography (GPC). This test method uses commercially available polystyrene standards and equipment and is applicable to polyethylenes (excluding high pressure low density polyethylene–LDPE) and polypropylenes soluble in 1,2,4-trichlorobenzene (TCB) at 140°C. This test method is not absolute and requires calibration.

Note 1Size exclusion chromatography (SEC) often is used as an alternative name for gel permeation chromatography (GPC).
Note 2Specific methods and capabilities of users may vary with differences in columns, instrumentation, applications software, and practices between laboratories.
Note 3One general method is outlined herein; alternative analytical practices can be followed and are attached in notes where appropriate.
Note 4There is no known ISO equivalent to this standard.

1.2The values stated in SI units, based on IEEE/ASTM S1-10, are to be regarded as the standard.

1.3This 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.
