ASTM International - ASTM D5462-13
Standard Test Method for On-Line Measurement of Low-Level Dissolved Oxygen in Water
Organization: | ASTM International |
Publication Date: | 15 June 2013 |
Status: | inactive |
Page Count: | 6 |
ICS Code (Examination of water for chemical substances): | 13.060.50 |
significance And Use:
5.1 DO may be either a corrosive or passivating agent in boiler/steam cycles and is therefore controlled to specific concentrations that are low relative to environmental and wastewater treatment... View More
scope:
1.1 This test method covers the on-line determination of dissolved oxygen (DO) in water samples primarily in ranges from 0 to 500 μg/L (ppb), although higher ranges may be used for calibration. On-line instrumentation is used for continuous measurements of DO in samples that are brought through sample lines and conditioned from high-temperature and high-pressure sources when necessary.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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. For specific hazards statements, see 6.5.
