This test method was developed primarily for the determination of traces of mercury in chlorine produced by the mercury-cell process.

1. Scope

1.1 This test method covers the determination of mercury in liquid chlorine with a lower limit of detection of 0.1 μg/L.

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. Specific precautionary statements are given in Sections 7, 6.3, 6.4, 6.5, and Note 2.

1.4 Review the current material safety data sheet (MSDS) for detailed information concerning toxicity, first-aid procedures, and safety precautions.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
