ASTM D5815-95(2001)e1

Withdrawn Rationale:

This test method covered a liquid-chromatographic procedure for the separation of some additives currently used in linear low-density polyethylene. These additives are extracted with either isobutanol or isopropanol prior to liquid-chromatographic separation. The ultraviolet absorbance (200 nm) of the compound(s) is measured; quantitation is performed using the internal standard method.

Formerly under the jurisdiction of Committee D20 on Plastics, this test method was withdrawn in February 2009 and replaced by Test Method D 6953 for Determination of Antioxidants and Erucamide Slip Additives in Polyethylene Using Liquid Chromatography (LC).

1.1 This test method covers a liquid-chromatographic procedure for the separation of some additives currently used in linear low-density polyethylene. These additives are extracted with either isobutanol or isopropanol prior to liquid-chromatographic separation. The ultraviolet absorbance (200 nm) of the compound(s) is measured; quantitation is performed using the internal standard method.

1.2 This 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. Specific precautionary statements are given in Section 9.

Note 1—There is no equivalent ISO standard.
