1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage.

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.
