METHOD OF TESTING STRUCTURAL MATERIALS FOR BIOSTABILITY Russian patent published in 2012 - IPC G01N33/38

Abstract RU 2471188 C1

FIELD: chemistry.

SUBSTANCE: method involves dipping and holding samples of the test materials at room temperature into a weakly aggressive medium - mixture of organic acids: 0.9-1.1% acetic acid, 0.9-1.1% citric acid, 0.09-0.12% oxalic acid, said acids being in ratio of 1.8:2.7:0.8-2.1:3.1:1.2. After exposure, the samples are removed and dried to constant weight and their strength characteristics are then determined.

EFFECT: high efficiency and reliability of tests.
