Laboratory chemists are needed to perform an interlaboratory study
that will determine the chromic oxide content of leather using
atomic absorption spectroscopy. The study will introduce an alternative
method to ASTM D 2807, Standard Test Method for Chromic Oxide
in Leather (Perchloric Acid Oxidation).
Participants must have the ability to perform D 2807, as well
as atomic absorption analysis, says Lori Hyllengren, secretary
of ASTM Committee D31 on Leather. Testers from the leather or
environmental industries and other laboratory chemists are invited.
The test is being coordinated by ASTM Subcommittee D31.06 on Chemical
AnalysisGeneral, part of Committee D31 on Leather. For further
technical information, contact Lori Hyllengren, lab manager, S B Foot Tanning Co., Bench St., Red Wing, MN 55066
(651/388-4731). Committee D31s next meeting is tentatively slated
for October at the ALCA Headquarters/ Leather Research Institute
of Texas Tech in Lubbock, Texas. For further meeting or membership
information, contact D31 manager Tim Brooke, ASTM (610/832-9729). //
