1.1 These test methods cover the determination of low-level (∧lt;100 [mu]g/L) dissolved oxygen in thermal-cycle steam condensate, deaerated boiler feedwater, boiler water, and deaerated deionized water. The following test methods are included:
Range, mg/L Sections Test Method A--Color Comparator Test 0 to 100 8 to 17 Method Using Self-Filling Glass Ampoules Test Method B--Instrument Test Method 0 to 100 18 to 26 Using Self-Filling Glass Ampoules1.2 These test methods may be applicable to electronic-grade, pharmaceutical-grade, and other high-purity waters, although these were not addressed in the collaborative study.
1.3 Test Method A is a colorimetric procedure applicable to dissolved oxygen in water in the range from 0 to 100 [mu]g/L.
1.4 Test Method B is an instrumented colorimetric procedure applicable to dissolved oxygen in water in the range from 0 to 100 [mu]g/L.
1.5 It is the user's responsibility to ensure the validity of these test methods for waters of untested matrices.
1.6 The values stated in SI units are to be regarded as the standard.
1.7 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.
