1.1.2 Sample Tube Insertion
Tubes with the nominal dimensions of 1-7/16' I.D. and two inches (2') s 1/4'
in length will be made. Maximum departure from perpendicularity to the as;s by
either end: 1.0 degree. Maximum out of plane allowance for ends; 0.025 inch.
After the specimens have been cast, the test specimens will be sealed and allowed
to remain undisturbed for a seven (7) day period to permit the polymer/waste
mixture to cure. At the end of the curing period, each specimen will be opened
and the core tube removed. Labeling will be accomplished using the procedure
with the exception that each specimen is not directly labeled, but placed in a
prelabeled, sealed container. For example, the second specimen from the tube
of specimen LZ will carry a label LZA2 on the container. Six (6) specimens
obtained from each solidification, three (3) will be leached in distilled water and
three (3) will be leached in synthetic sea water (per ANSI 16.1 and Section 2.2).
All six ( 6) samples per specimen will be used for the ninety (90) day immersion
test (Section 2.3).
1.13 Mibng of the waste streams and polymer will be accomplished using a high shear
energy mixing technique.
In preparing for the solidification, the polymer will be mixed. This is done to
minimiz e introduction of a random variable into any solidification. The
surrogated waste will be mixed to minimize introduction of a random variable into
any solidification. All components will be preweighed prior to the start of
solidi5cation.
1.1.4 Specimen Cast Preparation
After mixdttg of all the components, the polymer/waste mixture will be poured
into the tubes. All the specimens generated will be covered and allowed to cure
for seven (7) days. The remainder of the polymer/waste mixnue will be used to
obtain a esothertn profile and to determine Free L'quids ( Section 2.7).
