Ethanol for industrial use — Methods of test — Part 6: Test for miscibility with water
The principle of the procedure consists in addition of water to a test portion, under specified conditions, and examination for opalescence against a black background with side illumination, using a second Nessler cylinder containing water as the standard. - International Standards ISO 1388/1 to ISO 1377/12 cancel and replace ISO Recommendation R 1388-1970 of which they constitute a technical revision.
ISO 1388-6:1981, developed by the International Organization for Standardization (ISO), outlines the method for testing miscibility with water in ethanol for industrial use. This standard is a critical part of the ISO 1388 series, providing internationally recognized procedures to ensure the purity and quality of industrial ethanol. By specifying exact test methods, ISO 1388-6 supports industries in confirming that ethanol blends uniformly with water, a key quality indicator for various industrial processes.
ISO 1388-6:1981 is widely utilized in industries where ethanol serves as a chemical intermediate, solvent, or processing aid. Key applications include:
ISO 1388-6:1981 is part of a comprehensive suite of ethanol testing standards, ensuring a holistic approach to ethanol quality:
