SUITABILITY OF ASTM TEST METHOD D-2369 FOR DETERMINATION OF VOC IN HIGH SOLIDS COATINGS

The Technical Committee of the Philadelphia Society for Coatings Techn ology conducted a ''round-robin'' study of ASTM D 2369-89, the method used to determine volatile organic content (VOC) in coatings. Initiall y seven laboratories undertook the testing of five coatings. Two of th ese coatings were single component and the remaining three were two-co mponent, high solids coatings. An analysis of variance was performed o n the data obtained. The results indicated that the procedure can prod uce reliable results, when single-component coatings are tested. Howev er, data from two-component coatings yielded higher results than expec ted with large standard deviations.
