Standard Test Methods of Sampling and Chemical Analysis of Chlorine-Containing Bleaches

2016-08-04 /Historical
Superseeded by:

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.


1.1 These test methods cover the sampling and chemical analysis of chlorine-containing bleaches. The methods appear in the following order:

Sodium Hypochlorite (Soda Bleach) Solutions:
Sampling 5
Available Chlorine6-9
Sodium Chlorate10-14
Total Chlorine15-18
Sodium Chloride19 and 20
Total Alkalinity as Sodium Oxide (Na2O)21-24
Free Alkali as Sodium Hydroxide (NaOH)25-28
Calcium Hypochlorite:
Available Chlorine31-34
Chloroisocyanuric Acids and Their Derived Salts:
Available Chlorine (IodometricThiosulfate Method)43-46
Available Chlorine (ArseniteIodometric Method)47-50
