1.1 This test method covers the determination of low-level (<100μ g/L) dissolved oxygen in thermal-cycle steam condensate, deaerated boiler feedwater, boiler water, and deaerated deionized water. The following test method is included:

Range, μg/LSections
Color Comparator Test
Method Using Self-Filling Glass
Ampoules
0 to 100 8 to 17

1.2 This test method may be applicable to electronic-grade, pharmaceutical-grade, and other high-purity waters, although these were not addressed in the collaborative study.

1.3 This test method is a colorimetric procedure applicable to dissolved oxygen in water in the range from 0 to 100 μg/L.

1.4 It is the user''s responsibility to ensure the validity of these test methods for waters of untested matrices.

1.5 The values stated in SI units are to be regarded as the standard.

1.6 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.

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

8.2 This test method was tested in steam condensate, deaerated boiler feedwater, and deaerated deionized water. It is the user''s responsibility to ensure the validity of the test method for waters of untested matrices.
