DIN EN ISO 11885:2009-09 EN ISO 11885:2009 (E) 4 Introduction When applying this International Standard, it is necessary in each case, depending on the range to be tested, to determine if and
37、to what extent additional conditions should be established. DIN EN ISO 11885:2009-09 EN ISO 11885:2009 (E) 5 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 an
38、y, 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
39、 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 el
40、ements: 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, v
41、anadium, 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 15587-1 or ISO 15587-2). The method is suitable for mass concent
42、rations 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
43、 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.
