This document is applicable to devices for the generation and dosing of ozone. The ozone is generated in these devices according to the technology of dielectric barrier discharge. According to EN 1278 and EN 15074, ozone is suited for the use of the treatment of water intended for human consumption (drinking water), and for the treatment of swimming pool water respectively. Ozone can be added to the water for disinfection and for oxidative purposes. This document can also be applied for other technologies to generate ozone, e.g. electrolysis or UV irradiation, as far as reasonable or applicable.
This document specifies device’s construction, and test methods for the equipment used for in situ generation of ozone. It also specifies requirements for instructions for installation, operation, maintenance, safety and for documentation to be provided with the product.

This document specifies a method for the determination of the dissolved fraction of selected perfluoroalkyl and polyfluoroalkyl substances (PFAS) in non-filtrated drinking water using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The applicability of the method to other types of water like fresh waters (e.g. ground water, surface water) or treated wastewater can be validated separately for each individual case.
For each target compound both, eventually occurring branched isomers and the respective non-branched isomer, are quantified together. The selected set of substances determined by this method is representative for a wide variety of PFAS. This method has been validated for the analytes specified in Table 1. The list given in this table can be modified depending on the purpose and focus of the method. The lower application range of this method can vary depending on the sensitivity of the equipment used and the matrix of the samples. For many substances to which this document applies a limit of quantification (LOQ) of 1 ng/l can be achieved. Using high volume direct injection as described in part A or SPE as described in part B of the method allows lower LOQs. Analytical limitations can occur with short-chain PFAS or PFAS with more than ten carbon atoms in the carbon chain. Actual LOQs can depend on the blank values realized by individual laboratories as well.
NOTE This document enables the analysis of those 20 PFAS which are listed in point 3 of Part B of Annex III of the EU Drinking Water Directive, EU 2020/2184 [4], for the surveillance of the parametric limit value of 0,10 µg/l for the sum of PFAS.
Furthermore, alternatives and substitutes for these PFAS substances can be analysed using this document as well.

This European Standard specifies the characteristics and the requirements for sulfamic acids and salts.
Similar to antiscalants as phosphonic acids and its salts (EN 15040) and polycarboxylates and its salts (EN 15039), sulfamic acid and its salts can be used alone or in combination with others drinking water substances as antifoulants (antiscalant effect) for membranes for the treatment of water intended for human consumption.
Sulfamic acid and salts are used in mixtures with sodium hydroxide and sodium hypochlorite or other drinking water chlorine based oxidizing agents as biofilm remover especially for reverse osmosis (RO) and nanofiltration membranes to prevent biofouling by microbiological contamination. The components will not pass the membrane and are rejected to the wastewater with the concentrate. For the other components EN standards are already exist.

This document specifies methods to determine 226Ra concentration by inductively coupled plasma mass spectrometry (ICP-MS). The mass concentrations obtained can be converted into activity concentrations. The method is applicable to test samples of drinking water, rainwater, surface and ground water, after proper sampling and handling, and test sample preparation. The detection limit depends on the sample volume, the instrument used, the background count rate, the detection efficiency, the counting time and the chemical yield. The detection limit of the method described in this document, using currently available equipment, is approximately 10 mBq·l-1, which is better than the WHO criteria for safe consumption of drinking water (1 Bq·l-1). This method covers the measurement of 226Ra in water at activity concentrations between 0,001 Bq·l−1 and 100 Bq·l−1. Samples with concentrations higher than 1 Bq·l−1 can be measured if a dilution is performed. The method described in this document is applicable in the event of an emergency situation. In this method, filtration of the test sample is necessary. The analysis of 226Ra adsorbed to suspended matter is not covered by this method. The analysis of the insoluble fraction requires a mineralization step that is not covered by this document. In this case, the measurement is made on the different phases obtained. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

This document specifies a method for the determination of the elements aluminium, antimony, arsenic,
barium, beryllium, bismuth, boron, cadmium, caesium, calcium, cerium, chromium, cobalt, copper,
dysprosium, erbium, gadolinium, gallium, germanium, gold, hafnium, holmium, indium, iridium, iron,

thulium, tin, titanium, tungsten, uranium and its isotopes, vanadium, yttrium, ytterbium, zinc and
zirconium in water (e.g. drinking water, surface water, ground water, waste water and eluates).
Taking into account the specific and additionally occurring interferences, these elements can be
determined in water and digests of water and sludge (e.g. digests of water as described in ISO 15587-1
or ISO 15587-2).
The working range depends on the matrix and the interferences encountered. In drinking water and
relatively unpolluted waters, the limit of quantification (LOQ) lies between 0,002 μg/l and 1,0 μg/l for
most elements (see Table 1). The working range typically covers concentrations between several ng/l
and mg/l depending on the element and specified requirements.
The quantification limits of most elements are affected by blank contamination and depend
predominantly on the laboratory air-handling facilities available on the purity of reagents and the
cleanliness of glassware.
The lower limit of quantification is higher in cases where the determination suffers from interferences
(see Clause 5) or memory effects (see ISO 17294-1).
Elements other than those mentioned in the scope can also be determined according to this document
provided that the user of the document is able to validate the method appropriately (e.g. interferences,
sensitivity, repeatability, recovery).

This document specifies the derivation of biological equivalence (BEQ) concentrations for results of in vitro bioassays which are based on measuring effects on a biological process such as enzyme induction or cellular growth. The concept described here can be used for any biological assay after the proof of its applicability.
To derive BEQ concentrations, the effect on a biological process caused by a sample – i.e. the activity of the sample – is expressed in terms of a concentration of a reference compound which results in an equivalent effect on the process. The term "sample" used in this document addresses environmental samples as well as defined mixtures and pure compounds used as test item in a bioassay.

This document specifies a method for the simultaneous measurement of 3H and 14C in water samples by liquid scintillation counting of a source obtained by mixing the water sample with a hydrophilic scintillation cocktail. The method presented in this document is considered a screening method because of the potential presence of interfering radionuclides in the test sample. However, if the sample is known to be free of interfering radionuclides then 3H and 14C can be measured quantitatively. The method can be used for any type of environmental study or monitoring. This method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater having an activity concentration ranging from 5 Bq∙l-1 to 106 Bq∙l-1 (upper limit of the liquid scintillation counters for direct counting). For higher activity concentrations, the sample can be diluted to obtain a test sample within this range.
