Anotácia textu normy ASTM D2022-89(2016) :
These test methods detail the standard procedures for the sampling and chemical analysis of chlorine-containing bleaches including sodium hypochlorite (soda bleach) solutions, calcium hypochlorite, and chloroisocyanuric acids and their derived salts. Tests for sodium hypochlorite include the determination of available chlorine, sodium chlorate, total chorine, sodium chloride, total alkalinity as sodium oxide, and free alkali as sodium hydroxide. Tests for calcium hypochlorite include the determination of available chlorine, and water. And finally, tests for chloroisocyanuric acids and their derived salts include the determination of available chlorine by iodometric-thiosulfate and arsenite-iodometric methods, and moisture.
Keywords:
