Water quality - Determination of selected highly volatile organic compounds in water - Method using gas chromatography and mass spectrometry by static headspace technique (HS-GC-MS) (ISO 20595:2018)
ISO 20595:2018 specifies a method for the determination of selected volatile organic compounds in water (see Table 1). This comprises among others volatile halogenated hydrocarbons as well as gasoline components (BTXE, TAME, MTBE and ETBE).
The method is applicable to the determination of volatile organic compounds (see Table 1) in drinking water, groundwater, surface water and treated waste water in mass concentrations >0,1 µg/l. The lower application range depends on the individual compound, the amount of the blank value and the matrix.
Wasserbeschaffenheit - Bestimmung ausgewählter leichtflüchtiger organischer Verbindungen in Wasser - Verfahren mittels Gaschromatographie und Massenspektrometrie nach statischer Headspacetechnik (HS-GC-MS) (ISO 20595:2018)
Dieses Dokument legt ein Verfahren für die Bestimmung von ausgewählten leichtflüchtigen organischen Verbindungen in Wasser (siehe Tabelle 1) fest. Hierbei handelt es sich z. B. um leichtflüchtige Halogenkohlenwasserstoffe (LHKW) sowie um Benzininhaltstoffe (BTXE, TAME, MTBE und ETBE).
Das Verfahren ist anwendbar auf die Bestimmung von leichtflüchtigen organischen Verbindungen (siehe Tabelle 1) in Trink , Grund , Oberflächenwasser und Abwasser in Massenkonzentrationen >0,1 µg/l. Der untere Anwendungsbereich ist von der individuellen Verbindung, der Höhe des Blindwerts und der Matrix abhängig.
Die Anwendbarkeit des Verfahrens auf weitere, in Tabelle 1 nicht genannte, leichtflüchtige organische Verbindungen ist nicht ausgeschlossen, sie muss jedoch im Einzelfall geprüft werden.

Qualité de l'eau - Dosage de composés organiques hautement volatils sélectionnés dans l'eau - Méthode par chromatographie en phase gazeuse par la technique de l'espace de tête statique et spectrométrie de masse (HS-GC-MS) (ISO 20595:2018)
ISO 20595:2018 spécifie une méthode pour le dosage de composés organiques volatils sélectionnés dans l'eau (voir Tableau 1). Ceux-ci comprennent, entre autres, des hydrocarbures halogénés volatils ainsi que des constituants de l'essence (BTXE, TAME, MTBE et ETBE).
La méthode est applicable au dosage de composés organiques volatils (voir Tableau 1) présents dans l'eau potable, les eaux souterraines, les eaux de surface et les eaux résiduaires traitées à des concentrations massiques > 0,1 µg/l. La limite inférieure du domaine d'application dépend du composé particulier, de l'importance de la valeur du blanc et de la matrice.
Kakovost vode - Določevanje izbranih lahko hlapnih organskih spojin v vodi - Metoda s plinsko kromatografijo s statično "headspace" tehniko in z masno spektrometrijo (HS-GC-MS) (ISO 20595:2018)
Standard ISO 20595:2018 določa metodo za določanje izbranih hlapnih organskih spojin v vodi (glej preglednico 1). To med drugim vključuje hlapne halogenirane ogljikovodike ter sestavine bencina (BTXE, TAME, MTBE in ETBE).
Metoda se uporablja za določanje hlapnih organskih spojin (glej preglednico 1) v pitni vodi, podtalnici, površinski vodi in očiščeni odpadni vodi v masnih koncentracijah >0,1 µg/l. Spodnje področje uporabe je odvisno od posamezne spojine, vrednosti slepega vzorca in matrice.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
