ASTM D5543 - 15 Standard Test Method for Low-Level

1.1 This test method covers the rapid determination of low-level (<100 μg/L) dissolved oxygen in thermal-cycle steam condensate, deaerated boiler feedwater, boiler water, and deaerated deionized water. Color comparators allow the estimation of concentrations ranging from 0 to 100 μg/L (ppb) oxygen.

Steam Boilers | HVAC Heating Systems | Hydronics

The steam boiler must super-heat the water inside the water cavity to more than 212 degrees F. If the proper controls are not in the system a steam boiler can reach dangerous temperatures and possibly cause a fire. For a steam boiler to operate at the proper temperatures it needs some basic safety controls. Some of these are:
