E2941-13 Practice for Nitric Acid-Extraction of Elements from Ores and Related Metallurgical Materials by Closed Vessel Microwave Heating is being revised with title change to include a total acid digestion method, since partial extraction with nitric acid may not provide the total metal content required for metallurgical accounting.
