Fill the bath ¾ full with deionized water add the appropriate amount of FREIGUARD 315 for your application. Fill to final working volume and mix. Heat the solution to operating temperature.
Concentration: Using a 50ml volumetric pipette or graduated cylinder, transfer a 50ml sample of the FREIGUARD 315 bath into a clean 250ml Erlenmeyer flask. Add 5-10 drops of Indicating Solution #4 (0.1 % Methyl Orange) and 50mls of distilled or deionized water. Titrate with Testing Solution 60 (1.0 N HCL) from a marigold to permanent rose endpoint. Record the buret reading as the Total Alkalinity. For bath samples greater than 10% v/v titrate a 10ml sample size and multiply the result by 5 and record as Total Alkalinity.
Calculate the concentration of FREIGUARD 315 using the formula:
%V/V FREIGUARD 315 = mls of TS60 X 0.55
