Water quality - Multi-compound class methods - Part 2: Criteria for the quantitative determination of organic substances using a multi-compound class analytical method (ISO 21253-2:2019)
This document specifies the criteria for developing an in-house mass spectrometry-based method for quantitative analysis of multiple subgroups of organic substances in the scope of physical-chemical analysis of water.
This document supplements ISO/TS 13530 which provides guidance on the initial characterization of the measurement performances, by providing details to select the test matrix and internal standards and criteria for analyte and internal standard recoveries.
This document is not intended as a substitute for the currently applicable analytical standards dedicated to organic compounds but as a resource bringing additional characterization elements.
Wasserbeschaffenheit - Gemeinsam erfassbare Stoffgruppen - Teil 2: Kriterien für die quantitative Bestimmung organischer Stoffe mit einem Multianalyt-Verfahren (ISO 21253-2:2019)
Dieses Dokument legt die Kriterien für die Entwicklung einer massenspektrometrischen laborinternen Methode zur quantitativen Analyse multipler Untergruppen organischer Stoffe im Rahmen der physikalisch-chemischen Untersuchung von Wasser fest.
Dieses Dokument ergänzt ISO/TS 13530, die Anleitung für die erstmalige Charakterisierung der Messleistungen bereitstellt, indem es detaillierte Angaben zur Auswahl der Prüfmatrix, der internen Standards und der Kriterien für die Wiederfindungen von Analyten und internen Standards macht.
Dieses Dokument ist nicht als Ersatz für die aktuell anzuwendenden Normen vorgesehen, die für die Analyse organischer Stoffe bestimmt sind, sondern vielmehr als Hilfsmittel, das weitere Charakterisierungselemente einbringt.
Qualité de l'eau - Méthodes d'analyse de composés multi-classes - Partie 2: Critères pour la détermination quantitative de composés organiques avec une méthode d'analyse de composés multi-classes (ISO 21253-2:2019)
Le présent document spécifie les critères pour le développement en interne d'une méthode fondée sur la spectrométrie de masse pour l'analyse quantitative de multiples sous-groupes de composés organiques dans le cadre d'une analyse physicochimique de l'eau.
Le présent document complète l'ISO/TS 13530 qui fournit des recommandations sur la caractérisation initiale des performances de mesure, en détaillant la sélection de la matrice d'essai et des étalons internes, ainsi que les critères pour la récupération de l'analyte et des étalons internes.
Le présent document n'a pas vocation à se substituer aux normes analytiques dédiées aux composés organiques actuellement en vigueur, mais est destiné à apporter des éléments de caractérisation supplémentaires.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
