8 SS-EN ISO 11885:2009 (E) Provläsningsexemplar / Preview ISO 11885:2007(E) Introduction When applying this International Standard, it is necessary in each case, depending on the range to be tested, to determine if and to what extent additional conditions should be established. v ISO 2007 All rights reserved v

9 SS-EN ISO 11885:2009 (E) Water quality Determination of selected elements by inductively coupled plasma optical emission spectrometry (ICP-OES) WARNING Persons using this International Standard should be familiar with normal laboratory practice. This International Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. IMPORTANT It is absolutely essential that tests conducted according to this International Standard be carried out by suitably trained staff. 1 Scope This International Standard specifies a method for the determination of dissolved elements, elements bound to particles ( particulate ) and total content of elements in different types of water (e.g. ground, surface, raw, potable and waste water) for the following elements: aluminium, antimony, arsenic, barium, beryllium, bismuth, boron, cadmium, calcium, chromium, cobalt, copper, gallium, indium, iron, lead, lithium, magnesium, manganese, molybdenum, nickel, phosphorus, potassium, selenium, silicon, silver, sodium, strontium, sulfur, tin, titanium, tungsten, vanadium, zinc and zirconium. Taking into account the specific and additionally occurring interferences, these elements can also be determined in digests of water, sludges and sediments (for example, digests of water as specified in ISO or ISO ). The method is suitable for mass concentrations of particulate matter in waste water below 2 g/l. The scope of this method may be extended to other matrices or to higher amounts of particulate matter if it can be shown that additionally occurring interferences are considered and corrected for carefully. It is up to the user to demonstrate the fitness for purpose. Recommended wavelengths, limits of quantification and important spectral interferences for the selected elements are given in Table 1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Accuracy includes precision and trueness. 3.2 analyte element(s) to be determined 3.3 background equivalent concentration BEC elemental concentration required to produce an analyte signal with the same intensity as a background signal 3.4 calibration blank solution prepared in the same way as the calibration solution but leaving out the analyte 3.5 calibration solution solution used to calibrate the instrument, prepared from (a) stock solution(s) or from a certified standard 3.6 calibration check solution solution of known composition within the range of the calibration solutions, but prepared independently 3.7 determination entire process from preparing the test sample solution up to and including measurement and calculation of the final result 3.8 instrument performance check solution solution used to determine and control the instrument drift for relevant analytes 3.9 linearity straight line relationship between the (mean) result of measurement (signal) and the quantity (concentration) of the component to be determined 2 ISO 2007 All rights reserved

Precision depends only on the distribution of random errors and does not relate to true value or the specified 3.14 reagent blank solution prepared by adding to the solvent the same amounts of reagents as those added to the test sample solution (same final volume) 3.15 reproducibility precision under reproducibility conditions [ISO :2006, definition ] 3.16 reproducibility conditions observation conditions where independent test/measurement results are obtained with the same method on identical test/measurement items in different test or measurement facilities with different operators using different equipment [ISO :2006, definition ] ISO 2007 All rights reserved 3
