4.1 Trace amounts of water may be detrimental to the use of chlorine in some applications. The amount of water in the chlorine must be known to prevent problems during its use.

1.1 This test method is designed for the on-line determination of the content of water in liquid chlorine in the concentration range of 0.5 mg/kg (ppm) to 15 mg/kg (ppm). Consider water in chlorine can be analyzed over a range with an upper limit of 2030 µg/kg by this method, but may be applicable to a wider range.

1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.3 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.

1.4 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 7 and Note 3.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
