Influence of materials on water intended for human consumption - Influence due to migration - Part 2: Test method for non-metallic and noncementitious site-applied materials
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.
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. Es 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 des matériaux en contact sur l’eau destinée à la consommation humaine - Influence due à la migration - Partie 2 : Méthode d’essai des matériaux appliqués sur site, excepté les matériaux métalliques et ceux à base de ciment
Le présent document 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.
Il 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. Il traite de la migration dans l’eau de constituants issus de ces matériaux après que ceux ci aient été appliqués sur site.
Le présent document 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, comme les graisses ou les lubrifiants.
Vpliv materiala na pitno vodo - Vpliv migracije - 2. del: Metoda preskušanja nekovinskih in necementnih materialov
Ta dokument določa postopek za ugotavljanje migracije snovi iz nekovinskih in necementnih materialov, ki so pri uporabi v stiku s pitno vodo.
Uporablja se za materiale na kraju samem, namenjene uporabi v različnih pogojih za prevoz in shranjevanje pitne vode, vključno z neobdelano vodo, ki se uporablja za pripravo pitne vode. Zajema vodno ekstrakcijo snovi iz teh materialov, uporabljenih na kraju samem.
Dokument se uporablja za materiale, katerih fizikalne ali kemične lastnosti se spremenijo med nanosom na mestu uporabe ali po njem, kot so premazi, barve in lepila. Uporablja se tudi za nekatere druge materiale na kraju samem, ki se ne spreminjajo na tak način, npr. masti ali maziva.

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.
This document has been drawn up with the objective to describe a test method to determine the
migration of substances from products made from, or incorporating, organic and glassy
(porcelain/vitreous enamel) material for use in contact with water intended for human consumption.
Annex A, which is normative, describes an alternative arrangement for flushing pipes having a nominal
size greater than DN 80.
Annex B, which is informative, describes additional procedures for testing non-homogeneous products
and pipes having a nominal size greater than DN 80.
Annex C, which is informative, describes a schedule for the preparation of migration waters.
Annex D, which is informative, describes procedural tests using standard additions (positive controls).
Annex E, which is informative, describes the migration test procedure in a schematic manner.
This document will result in one of a series of standards on test methods which support the appropriate
standards.
With regards to potential adverse effect on the quality of water intended for human consumption,
caused by the material testing covered by this document:
1) This document provides no information as to whether the final product tested using this
methodology may be used without restriction in any of the Member States of the EU or EFTA.
2) It should be noted that, whilst awaiting the adoption of verifiable European criteria, existing
national regulations concerning the use of this material test method remain in force.
NOTE Conformity with this document does not confer or imply acceptance or approval of the material in any
of the Member States of the EU or EFTA. The use of the methodology covered by this document is subject to
regulation or control by National Authorities.
This document, Part 2, is the second in a series of standards for dealing with the influence of migration
from materials on water intended for human consumption, including:
— Part 1: Test method for factory-made products made from or incorporating organic and glassy
(porcelain/vitreous enamel) materials;
— Part 2: Test method for non-metallic and non-cementitious site-applied products;
— Part 3: Test method for ion exchange and absorbent resins;
— Part 4: Test method for water treatment membranes.
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.
