Round Robin Participants Sought for Leather Test By Atomic Absorption Spectroscopy

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 Analysis—General, 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 D31’s 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). //
