Title
Standard Test Method for Measurement of Hexane Extractable Content of Polyolefins
ASTM International
Publication Date:

Scope:
Scope
This test method describes an extraction/gravimetric procedure for
determination of the amount
of hexane soluble low molecular weight material present in
polyethylene, polypropylene,
ethylene-propylene copolymers, and ethylene-vinyl acetate copolymers.
This test method is a
modification of the Food and Drug Administration (FDA) procedure for
determining hexane
extractables of polyolefins. This test method is based upon the
presumption that the weight of the
residue extract present in the solvent is equal to the amount
extracted from the film sample and
could therefore be quantified by measuring the weight loss of the
extracted film, eliminating the
complex and time-consuming evaporation process described in 21 CFR
177.1520.
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.
The values stated in SI units are to be regarded as the standard.
Units used in 21 CFR 177.1520
are also used in this test method. Units are in conformance with
Federal Code 21 CFR 177.1520, from
which this test method is derived.
