Influence of materials on water intended for human consumption - GC-MS identification of water leachable organic substances

This European Standard describes a method for detecting and identifying organic chemicals that are amenable to GC-MS analysis using the procedures described and which can migrate from a product into water intended for human consumption. This European Standard does not provide all the necessary tools to completely identify all the substances that are detected. A method of semi-quantitatively estimating the concentrations of the organic substances detected is also provided, however, concentrations should only be seen as indicative.
NOTE   The method to be used for the preparation of migration waters is specified by separate EN's, as noted below.

Einfluss von Materialien auf Wasser für den menschlichen Gebrauch - Identifizierung mittels GC-MS von durch Wasser auslaugbaren organischen Substanzen

Diese Norm beschreibt eine Methode zur Detektion und Identifizierung organischer Substanzen, die der GC MS-Analyse mit den beschriebenen Verfahren zugänglich sind und von Produkten in Trinkwasser migrieren können. Diese Norm gibt nicht alle notwendigen Maßnahmen zur vollständigen Identifizierung sämtlicher gefundener Substanzen an. Ein Verfahren zur semi-quantitativen Bestimmung der Konzentrationen der ermittelten organischen Substanzen wird ebenfalls angegeben, jedoch sollten die Konzentrationen lediglich als Anhaltswerte gesehen werden.
ANMERKUNG   Das Verfahren zur Herstellung von Migrationswässern ist in anderen Europäischen Normen festgelegt, die nachfolgend genannt sind.

Influence sur l'eau des matériaux en contact avec l'eau destinée à la consommation humaine - Identification par CG-SM de substances organiques lixiviables à l’eau

La présente Norme européenne définit une méthode de détection et d’identification des substances chimiques organiques compatibles avec l’analyse par CG-SM par les modes opératoires décrits et capables de migrer d’un produit vers l’eau destinée à la consommation humaine. Elle ne fournit pas tous les outils nécessaires pour permettre l'identification complète de toutes les substances détectées. La présente norme fournit également une méthode d'estimation semi-quantitative des concentrations des substances organiques détectées. Il convient toutefois de considérer les concentrations comme étant seulement indicatives.
NOTE   La méthode de préparation des eaux de migration à utiliser est spécifiée dans d’autres Normes européennes, mentionnées ci-dessous.

Vpliv materialov na pitno vodo - Identifikacija GC-MS vodno lužljivih organskih snovi

Ta evropski standard opisuje metodo za identifikacijo organskih snovi, ki so primerne za analizo GC-MS z opisanimi postopki in ki lahko iz produkta migrirajo v pitno vodo. Navedena je tudi metoda semikvantitativne ocene koncentracij identificiranih organskih snovi
OPOMBA   Metoda, ki jo je treba uporabiti za pripravo migracijske vode, je opredeljena v ločenih standardih EN, kot so navedeni spodaj.
