Influence of cementitious products on water intended for human consumption - Test methods - Part 1: Influence of factory made cementitious products on organoleptic parameters
This European Standard specifies a method to determine the influence of factory made cementitious products on the odour, flavour, colour and turbidity of test waters after contact with the products.
This European Standard is applicable to factory made cementitious products, e.g. cement mortar linings to metallic pipes, tanks, concrete pipes etc. intended to be used for the transport and storage of water for human consumption, including raw water used for the production of drinking water.
Einfluss von zementgebundenen Produkten auf Wasser für den menschlichen Gebrauch - Prüfverfahren - Teil 1: Einfluss fabrikmäßig hergestellter zementgebundener Produkte auf organoleptische Parameter
Dieses Dokument legt ein Verfahren zur Bestimmung des Einflusses fabrikmäßig hergestellter zementgebundener Produkte auf Geruch, Geschmack, Färbung, Trübung N1 und den gesamten organischen Kohlenstoff (TOC, en: turbidity and total organic carbon) von Prüfwässern nach einem Kontakt mit den Produkten fest.
Dieses Dokument ist anwendbar auf fabrikmäßig hergestellte zementgebundene Produkte, z. B. Zementmörtelauskleidungen von metallischen Rohren, Behälter, Betonrohre usw., die dazu bestimmt sind, Trinkwasser zu transportieren und aufzubewahren, einschließlich Rohwasser, das für die Herstellung von Trinkwasser eingesetzt wird.
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 1 : Influence des produits à base de ciment fabriqués en usine sur les paramètres organoleptiques et la migration des substances organiques (COT)
Le présent document spécifie une méthode permettant de déterminer l’influence des produits à base de ciment fabriqués en usine sur l’odeur, la flaveur, la couleur, la turbidité et la teneur en carbone organique total (COT) des eaux d’essai après contact avec les produits concernés.
Le présent document s’applique aux produits à base de ciment fabriqués en usine, tels que les revêtements intérieurs de mortier de ciment appliqués sur des tubes métalliques, des réservoirs, des tubes en béton, etc., destinés à être utilisés pour le transport et le stockage de l’eau destinée à la consommation humaine, y compris l’eau brute utilisée pour la production de l’eau potable.
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
Vpliv cementnih proizvodov na pitno vodo – Preskusne metode – 1. del: Vpliv industrijsko izdelanih cementnih proizvodov na organoleptične parametre
Ta evropski standard določa metodo za ugotavljanje vpliva industrijsko izdelanih cementnih proizvodov na vonj, okus, barvo in motnost preskusne vode po stiku s takšnimi proizvodi.
Ta evropski standard se uporablja za industrijsko izdelane cementne proizvode (npr. obloge iz cementne malte za kovinske cevi, cisterne, betonske cevi itd.), namenjene za prevoz in shranjevanje pitne vode, vključno z neobdelano vodo, ki se uporablja za pripravo pitne vode.

European foreword
This document (EN 14944-1:2023) has been prepared by Technical Committee CEN/TC 164 “Water
supply”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2024, and conflicting national standards shall be
withdrawn at the latest by April 2024.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 14944-1:2006.
In comparison with EN 14944-1:2006, the following changes have been made:
— provisions for testing the influence of materials on the migration of organic substances (TOC) have
been added;
— the test method for TON /TFN according to EN 1622 has been specified according to the
revised EN 1420;
— requirements for disinfection (preconditioning with 50 mg/L chlorine) have been removed;
— a procedure for extending the number of migration periods has been included.
This document describes a test method to determine the influence(s) of factory-made cement based
products on organoleptic parameters and the migration of organic substances (TOC) in water intended
for human consumption.
This document will result in one of a series of standards that support standards for the approval of
products and materials in contact with water intended for human consumption.
This document is part of a series dealing with the influence of cement based and associated non-cement
based products/materials on water intended for human consumption, including:
— Part 1: Influence of factory-made cement based products on organoleptic parameters and migration
of organic substances (TOC)
— Part 2: Influence of site-applied cement based materials and associated non-cement based
products/materials on organoleptic parameters and migration of organic substances (TOC)
— Part 3: Migration of substances from factory-made cement based products
— Part 4: Migration of substances from site-applied cement based materials and associated non-cement
based products/materials
Any feedback and questions on this document should be directed to the users’ national standards body.
