FprEN 14944-4

Influence of cement based products on water intended for human consumption - Test methods - Part 4: Migration of substances from site-applied cement based materials and associated non-cement based products/materials

This document specifies a method to determine the migration of substances from hardened cement based site-applied or site-formed materials (including pre-packaged mortars) into test waters after contact with the products. It also covers determination of migration from individual constituents of cement based products and materials (see Annexes A and B) and from associated non-cement based products for approval purposes (see Annex C).
Site-applied or site-formed cement based materials which cannot be cast as cubes or prisms e.g. some spray applied systems, fall in the scope of EN 14944−3 and not under this standard.
This document is applicable to site-applied or site-formed cement based materials intended to be used for the transport and storage of water intended for human consumption, including raw water used for the production of drinking water. It is also applicable to individual constituents of cement based products/materials and to associated non-cement based products/materials.
NOTE   Tests with the specified test water will not necessarily be representative of materials used in different kinds of waters and especially very soft waters.

Einfluss zementgebundener Produkte auf Wasser für den menschlichen Gebrauch - Prüfverfahren - Teil 4: Migration von Substanzen aus bauseits angewendeten zementgebundenen Materialien und zugehörigen nicht zementgebundenen Produkten/Materialien

Dieses Dokument legt ein Verfahren zur Bestimmung der Migration von Substanzen aus erhärteten zementgebundenen bauseits angewendeten oder bauseits geformten Materialien (einschließlich vorverpacktem Mörtel) in Prüfwässer nach einem Kontakt mit den Produkten fest. Es deckt auch die Bestimmung der Migration einzelner Bestandteile von zementgebundenen Produkten und Materialien (siehe Anhang A und Anhang B) und von zugehörigen nicht zementgebundenen Hilfsstoffen für Zulassungszwecke ab (siehe Anhang C).
Bauseits angewendete oder bauseits geformte zementgebundene Materialien, die nicht in Würfel- oder prismatische Formen gegossen werden können, wie z. B. einige aufzuspritzende Systeme, fallen in den Anwendungsbereich von EN 14944-3 und nicht unter diese Norm.
Dieses Dokument gilt für bauseits angewendete oder bauseits geformte zementgebundene Materialien, welche dazu bestimmt sind, Trinkwasser zu transportieren und zu speichern, einschließlich Rohwasser, welches für die Herstellung von Trinkwasser eingesetzt wird. Es gilt auch für einzelne Bestandteile von zement-gebundenen Produkten/Materialien und zugehörigen nicht zementgebundenen Hilfsstoffen.
ANMERKUNG Prüfungen mit dem festgelegten Prüfwasser sind nicht unbedingt repräsentativ für Materialien, die in anderen Wasserarten und insbesondere in sehr weichem Wasser verwendet werden.

Influence des produits à base de ciment sur l’eau destinée à la consommation humaine - Méthodes d’essai - Partie 4 : Migration de substances à partir de matériaux à base de ciment appliqués sur site et de produits/matériaux associés exempts de ciment

Le présent document spécifie une méthode de détermination de la migration dans les eaux d’essai des substances issues de matériaux durcis à base de ciment appliqués ou formés sur site (y compris les mortiers préconditionnés). Il couvre également la détermination de la migration à partir de constituants individuels de produits et matériaux à base de ciment (voir les Annexes A et B) et à partir de produits associés exempts de ciment à des fins d’agrément (voir l’Annexe C).
Les matériaux à base de ciment appliqués ou formés sur site qui ne peuvent pas être coulés sous forme de cubes ou de prismes, par exemple, certains produits pulvérisés, relèvent du domaine d’application de l’EN 14944−3 et non de la présente norme.
Le présent document s’applique aux matériaux à base de ciment appliqués ou formés sur site conçus pour le transport et le stockage de l’eau destinée à la consommation humaine, y compris l’eau brute utilisée pour produire de l’eau potable. Il s’applique également aux constituants individuels des produits/matériaux à base de ciment ainsi qu’aux produits/matériaux associés exempts de ciment.
NOTE Les essais menés avec l’eau d’essai spécifiée ne seront pas nécessairement représentatifs d’une utilisation des matériaux dans une autre sorte d’eau et notamment dans les eaux très douces.
