Historical Standard: ASTM D2839-05 Standard Practice for Use of a Melt Index Strand for Determining Density of Polyethylene
SUPERSEDED (see Active link, below)
ASTM D2839
1. Scope
1.1 This practice covers the preparation of a sample for polyethylene density determination in accordance with Test Method D 1505. The sample consists of a strand produced by extrusion of the polyethylene in accordance with Test Method D 1238, Condition 190/2.16 (Melt Index).
1.2 The values stated in SI units are to be regarded as the standard. The values given in brackets are for information only.
1.3 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.
Note 1There is no similar or equivalent ISO standard.
