Doplňujúce informácie
| Significance and Use | ||||||||||
|
5.1 Chlorine is used to destroy or deactivate a variety of unwanted chemicals and microorganisms in water and wastewater. 5.2 An uncontrolled excess of chlorine in water, whether free available or combined, can adversely affect the subsequent use of the water. |

| 1. Scope | ||||||||||
|
1.1 This test method covers the determination of residual chlorine in water by direct amperometric titration. 1.2 Within the constraints specified in Section 1.3 Precision data for this test method were obtained on estuary, inland main stem river, fresh lake, open ocean, and fresh cooling tower blowdown water. Bias data could not be determined because of the instability of solutions of chlorine in water. It is the user's responsibility to ensure the validity of the test method for untested types of water. 1.4 In the testing by which this standard was validated, the direct and back starch-iodide titrations and the amperometric back titration, formerly part of this standard, were found to be unworkable and were discontinued in 1986. Historical information is presented in Appendix X1. 1.5 The values stated in SI units
are to be regarded as standard. No other units of measurement are
included in this 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. |
