This Code applies to deaerating heaters and deaerators equipped
with either shell-and-tube or direct contact, vent-condensing
sections.
The Code describes the test method and procedures for thed
etermination of dissolved oxygen in water for deaerating equipment
at concentrations up to 75 μg/L (ppb). This Code also
describes the method for determining the terminal temperature
difference (TTD).
Other methods of dissolved oxygen measurement are included in
Appendices A, B and C. These may be used as an adjunct to the
Code.
