|Publication Date:||10 December 1999|
|ICS Code (Examination of water for chemical substances):||13.060.50|
1.1 This test method covers the determination of dissolved and total recoverable elements in water, which includes drinking water, lake water, river water, sea water, snow, and reagent water Type II by d-c argon plasma atomic emission spectroscopy.
1.2 The information on precision and bias may not apply to other waters.
1.3 Table A1.1 of Annex A1 as shown in the ranges given in Table 1 but is not limited to the elements or ranges listed.
1.4 This test method is not applicable to brines unless the sample matrix can be matched or the sample can be diluted by a factor of 200 up to 500 and still maintain the analyte concentration above the detection limit.
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 and health practices and determine the applicability of regulatory limitations prior to use.
