Imaging materials. Methods for the evaluation of the effectiveness of chemical conversion of silver images against oxidation Ingestion-build-224916 you can efficiently manufacture high-quality1 Scope 1. 1 This International Standard describes methods for evaluating the effectiveness of chemical conversion treatments intended to increase the resistance of wet processed silver images to oxidation. The treatment may be applied as part of the original processing, or it may be a post processing treatment. This International Standard does not recommend general or specific treatments for silver images. Likewise, treatment temperature, times and
