Influence of metallic materials on water intended for human consumption - Method to evaluate the passive behaviour of stainless steels
This European Standard specifies a procedure to evaluate the passive behaviour of stainless steels used in construction products intended to come into contact with drinking water. The passive state of stainless steels is the reason why no relevant amounts of metals are released from these materials into the drinking water. This test is used to verify whether the stainless steel under consideration is passive under conditions which can occur in drinking waters.
Einfluss metallischer Werkstoffe auf Wasser für den menschlichen Gebrauch - Verfahren zur Ermittlung des Passivverhaltens von nichtrostenden Stählen
Diese Europäische Norm legt ein Verfahren zur Ermittlung des Passivverhaltens von nichtrostenden Stählen fest, die in Bauprodukten eingesetzt werden, die dafür vorgesehen sind, mit Trinkwasser in Kontakt zu kommen.
Der Passivzustand von nichtrostenden Stählen ist der Grund, weshalb keine relevanten Mengen an Metallen aus diesen Werkstoffen in das Trinkwasser abgegeben werden. Diese Prüfung wird angewendet, um zu verifizieren, ob der betreffende nichtrostende Stahl unter den Bedingungen passiv bleibt, die in Trinkwässern vorliegen können.
Influence des matériaux métalliques sur l'eau destinée à la consommation humaine - Méthode d'évaluation du comportement passif des aciers inoxydables
La présente Norme européenne spécifie un mode opératoire pour évaluer le comportement passif des aciers
inoxydables employés dans des produits de construction destinés à entrer en contact avec de l'eau potable.
C'est en raison de leur passivité que les aciers inoxydables ne relarguent pas de quantités significatives de
métaux dans l'eau potable. Cet essai sert à évaluer la passivité de l'acier inoxydable à l'étude dans des
conditions semblables à celles rencontrées dans l'eau potable.
Vpliv kovinskih materialov na pripravo pitne vode - Metoda za ovrednotenje pasivnega vedenja nerjavnih jekel
Ta evropski standard določa postopek za vrednotenje pasivnega vedenja nerjavnega jekla, ki se uporablja za gradbene proizvode, ki so namenjeni stiku s pitno vodo. Pasivno stanje nerjavnega jekla je razlog, da se v pitno vodo ne izločijo pomembne količine kovin iz teh materialov. Ta preskus se uporablja za preverjanje, ali je obravnavano nerjavno jeklo pasivno pod pogoji, do katerih lahko pride v pitni vodi.

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 January 2013, and conflicting national standards shall be withdrawn at the latest by January 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document is one of a series of test methods which support associated product standards. This document has been prepared under the mandate given to CEN by the Commission of the European Communities and the European Free Trade Area.
With respect to the potential adverse effects on the quality of water intended for human consumption caused by metallic materials, attention is drawn to the fact that the relevant national regulations remain in force until the adoption of verifiable European acceptance criteria. Water intended for human consumption is hereafter referred to as "drinking water" and means the same as the definition given at Article 2(1) of the Council Directive 98/83/EC on the quality of water intended for human consumption. This document describes the method to evaluate the passive behaviour of stainless steels in contact with water. The passive layer is the cause for the negligible release of metal ions from stainless steels into the drinking water.

When tested in a test rig as described in EN 15664-1 stainless steels show very low metal release rates and the resulting metal concentrations in the water are in most cases below the detection limits of available analytical instruments. The reason for these small metal release rates is the formation of a passive layer on the surface on stainless steels. It was therefore decided to test stainless steels for the properties of the passive layer and not metal release. The material under consideration is tested in an electrochemical test. For verification of the correct performance of the test protocol, the test is also performed in parallel on material 1.4404 which is passive in contact with drinking water but shows a clear pitting potential under the conditions of this test.

Foreword
This document (prEN 16056:2010) has been prepared by Technical Committee CEN/TC 164 “Water supply”,
the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This European Standard is one of a series of test methods which support associated product standards.
The standard has been prepared under the mandate given to CEN by the Commission of the European
Communities and the European Free Trade Area and supports essential requirements of the relevant EU
Directives.
With respect to the potential adverse effects on the quality of water intended for human consumption caused
by metallic materials, attention is drawn to the fact that the relevant national regulations remain in force until
the adoption of verifiable European acceptance criteria. Water intended for human consumption is hereafter
referred to as "drinking water" and means the same as the definition given at Article 2(1) of the Council
Directive 98/83/EC on the quality of water intended for human consumption.
This European Standard has been drafted in accordance with the CEN Internal Regulations, Part 3.
This European Standard is part of a series dealing with the test method to evaluate the influence of metals on
drinking water:
— Part 1: Dynamic Rig Test – Design and operation;
— Part 2: Dynamic Rig Test – Test waters;
1)
— Part 3: Dynamic Rig Test – Guidance on interpretation of results ;
— Determination of residual surface lead (Pb) — Extraction method;
— Method to evaluate the passive behaviour of stainless steels (this standard).
This document describes the method to evaluate the passive behaviour of stainless steels in contact with
water. The passive layer is the cause for the negligible release of metal ions from stainless steels into the
drinking water.

The material under consideration is tested in an electrochemical test. For verification of the correct
performance of the test protocol, the test is also performed in parallel on material 1.4404 for which the
relevant data are well known.
This test is terminated when the pitting potential of the material or the break-through potential is reached.
