For types requiring corrosion resistance (primarily Types B through F), effective sealing of the porous oxide layer is mandatory. The standard outlines methods to evaluate the quality of the seal, ensuring the aluminum is protected against staining and degradation.
Most coatings (except some Type A hard coats) must be sealed in water or chemical solutions to maximize corrosion resistance. astm b580-79 pdf
While this guide covers the core structure of the specification, accessing the official is essential for production and legal compliance because it contains: Precise chemical formulas for sealing test solutions. Exact tolerances for measurement instruments. For types requiring corrosion resistance (primarily Types B
