Influence of materials on water intended for human consumption - Influence due to migration - Part 2: Test method for non-metallic and non-cementitious site-applied materials
This European Standard specifies a procedure to determine the migration of substances from non-metallic and non-cementitious site-applied materials for use in contact with water intended for human consumption.
It is applicable to site-applied materials intended to be used under various conditions for the transport and storage of water intended for human consumption, including raw water used for the production of water intended for human consumption. It covers the extraction by water of constituents from these materials after their application on site.
The standard is applicable to materials whose physical or chemical properties alter during or after on-site application, such as coatings, paints, and adhesives. In addition, some site-applied materials that do not change in such a manner, e.g. greases or lubricants, are also included.
Einfluss von Materialien auf Trinkwasser - Einfluss infolge der Migration - Teil 2: Prüfverfahren für vor Ort aufgebrachte nicht metallische und nicht zementgebundene Materialien
Dieses Dokument legt ein Verfahren zur Bestimmung der Migration von Stoffen aus vor Ort aufgebrachten
nicht metallischen und nicht zementgebundenen Materialien fest, die für die Verwendung in Kontakt mit dem
für den menschlichen Gebrauch bestimmten Wasser vorgesehen sind.
Es gilt für vor Ort aufgebrachte Materialien, die zum Einsatz unter unterschiedlichen Bedingungen für den
Transport und die Speicherung von für den menschlichen Gebrauch bestimmtem Wasser, einschließlich von
Rohwasser, das für die Herstellung von für den menschlichen Gebrauch bestimmtem Wasser verwendet wird,
vorgesehen sind. Sie behandelt die Extraktion von Bestandteilen aus diesen Materialien durch Wasser nach
ihrer Aufbringung vor Ort.
Dieses Dokument ist auf Materialien anwendbar, deren physikalische oder chemische Eigenschaften sich bei
oder nach der Aufbringung vor Ort ändern, wie z. B. Beschichtungsstoffe, Anstrichstoffe und Klebstoffe.
Außerdem sind auch einige vor Ort aufgebrachte Materialien enthalten, die sich nicht auf diese Art und Weise
verändern, wie z. B. Schmierfette oder Schmierflüssigkeiten.
Influence sur l'eau des matériaux destinés à entrer en contact avec l'eau destinée à la consommation humaine - Influence de la migration - Partie 2 : Méthode d'essai des matériaux appliqués sur site excepté les matériaux métalliques et ceux à base de ciment
La présente Norme européenne spécifie une méthode de détermination de la migration de substances à partir de
matériaux appliqués sur site, utilisés en contact avec l�eau destinée à la consommation humaine, à l�exception des
matériaux métalliques et de ceux à base de ciment.
La présente norme s�applique à des matériaux appliqués sur site utilisés dans diverses conditions pour le transport
et le stockage de l�eau destinée à la consommation humaine, y compris les eaux brutes pour la production d�eau
destinée à la consommation humaine. Elle traite de la migration dans l�eau de constituants issus de ces matériaux
après que ceux-ci aient été appliqués sur le site.
La présente Norme s�applique aux matériaux dont les propriétés physiques ou chimiques se modifient pendant ou
après leur application sur site, tels que les enduits, peintures et adhésifs. De plus, sont également inclus certains
matériaux appliqués sur site qui ne se modifient pas de la sorte comme, par exemple, les graisses ou les lubrifiants.

Introduction
In respect of potential adverse effects on the quality of water intended for human consumption caused by the
materials, it is called to mind that, while awaiting the adoption of verifiable European acceptance criteria, the
relevant national regulations remain in force.
1 Scope
This document specifies a procedure to determine the migration of substances from non-metallic and non-
cementitious site-applied materials for use in contact with water intended for human consumption.
It is applicable to site-applied materials intended to be used under various conditions for the transport and
storage of water intended for human consumption, including raw water used for the production of water
intended for human consumption. It covers the extraction by water of substances from these materials after
their application on site.
The document is applicable to materials whose physical or chemical properties alter during or after on-site
application, such as coatings, paints, and adhesives. In addition, some site-applied materials that do not
change in such a manner, e.g. greases or lubricants, are also included.
