Construction products: Assessment of release of dangerous substances - Part 1: Guidance for the determination of leaching tests and additional testing steps
(1) This document allows the identification of the appropriate leaching test method for the determination of the release of RDS from construction products into soil, surface water and groundwater. This document provides a stepwise procedure for the determination of appropriate release tests, including:
a) determination of the test method based on general product properties;
b) choice of the test method using specific product properties.
(2) Furthermore, this document gives general guidance for CEN Technical Product Committees and EOTA WGs on basic aspects (sampling, sample preparation and storage, eluate treatment, analysis of eluates and documentation) to be specified in the relevant product standards or ETAs.
(3) Metallic products and coatings on metallic products are not considered in the determination scheme of this document since the test methods in prEN 16637 2:—1) (tank test) and prEN 16637 3:—2) (column test) are not appropriate for the testing of these construction products due to a different release mechanism (solubility control).
NOTE See Annex F.
(4) It is assumed that intermittent contact with water (e.g. exposure to rainwater) is tested – by convention – as permanent contact. For some coatings, (e.g. some renders with organic binders according to EN 15824 [7]) in intermittent contact to water, physical and chemical properties might be altered in permanent contact with water. These products are not considered in the determination scheme of this document since the test method in prEN 16637 2 is not appropriate for the testing of these construction products (in this case EN 16105 [8] might be an alternative method).
Bauprodukte - Bewertung der Freisetzung von gefährlichen Stoffen - Teil 1: Leitfaden für die Festlegung von Auslaugprüfungen und zusätzlichen Prüfschritten
Dieses Dokument ermöglicht die Identifizierung des geeigneten Auslaugprüfverfahrens für die Bestimmung der Freisetzung regulierter gefährlicher Stoffe aus Bauprodukten in den Boden, das Oberflächenwasser und das Grundwasser. Dieses Dokument enthält ein schrittweises Verfahren zur Ermittlung geeigneter Freisetzungsprüfungen, einschließlich:
a) Bestimmung des Prüfverfahrens auf der Grundlage allgemeiner Produkteigenschaften;
b) Wahl des Prüfverfahrens durch Anwendung spezieller Produkteigenschaften.
Darüber hinaus enthält dieses Dokument einen Leitfaden für die Technischen Produktkomitees von CEN und Arbeitsgruppen (WG) der Europäischen Organisation für Technische Bewertung EOTA zu grundlegenden Aspekten (Probenahme, Probenvorbereitung und -lagerung, Eluatbehandlung, Analyse von Eluaten und Dokumentation), die in den maßgebenden Produktnormen oder Europäischen Technischen Bewertungen (ETA) festzulegen sind.
Metallische Produkte und Beschichtungen auf metallischen Produkten werden in diesem Dokument nicht berücksichtigt, da die Prüfverfahren in EN 16637 2 (Trog-Prüfverfahren) und EN 16637 3 (Perkolationsprüfung) für die Prüfung dieser Bauprodukte aufgrund eines anderen Freisetzungsmechanismus (Löslichkeitssteuerung) nicht geeignet sind.
ANMERKUNG Siehe Anhang F.
Es wird angenommen, dass der zeitweilige Kontakt mit Wasser (z. B. Beanspruchung durch Regenwasser) nach Vereinbarung als dauerhafter Kontakt geprüft wird. Bei einigen Beschichtungen (z. B. einige Putze mit organischen Bindemitteln nach EN 15824 [7]), die zeitweilig mit Wasser in Berührung kommen, könnten physikalische und chemische Eigenschaften sich bei dauerhaftem Kontakt mit Wasser verändern. Diese Produkte werden nicht in diesem Dokument berücksichtigt, da das Prüfverfahren in EN 16637 2 für die Prüfung dieser Bauprodukte nicht geeignet ist (in diesem Fall könnte EN 16105 [8] ein geeignetes alternatives Prüfverfahren sein.)
Produits de construction - Évaluation du relargage de substances dangereuses - Partie 1 : Guide pour la spécification des essais de lixiviation et des étapes supplémentaires d’essai
Le présent document permet l’identification de la méthode d’essai de lixiviation appropriée pour déterminer le relargage de SDR issues de produits de construction dans le sol, les eaux de surface et les eaux souterraines. Le présent document fournit un mode opératoire par étapes pour la détermination des essais de relargage appropriés, comprenant :
a) la détermination de la méthode d’essai basée sur les propriétés générales du produit ;
b) le choix de la méthode d’essai reposant sur des propriétés spécifiques du produit.
En outre, le présent document donne des recommandations générales pour les Comités techniques de produits du CEN et les groupes de travail de l’EOTA sur des aspects de base (échantillonnage, préparation des échantillons et stockage, traitement des éluats, analyse des éluats et documentation) à spécifier dans les normes de produits ou évaluations techniques européennes (ETE) correspondantes.
Les produits métalliques et revêtements de produits métalliques ne sont pas pris en compte dans le schéma de détermination du présent document, car les méthodes d’essai de l’EN 16637 2 (essai en réacteur) et de l’EN 16637 3 (essai en colonne) ne sont pas appropriées pour les essais de ces produits de construction du fait d’un mécanisme de relargage différent (contrôle de la solubilité).
NOTE Voir l’Annexe F.
Il est présumé que le contact intermittent avec l’eau (par exemple, exposition à l’eau de pluie) est considéré, par convention, comme un contact permanent. Pour certains revêtements (tels que certains enduits de maçonnerie organiques conformément à l’EN 15824[7]) en contact intermittent avec l’eau, certaines propriétés physiques et chimiques peuvent être altérées en cas de contact permanent avec l’eau. Ces produits ne sont pas pris en compte dans le schéma de détermination du présent document, car la méthode d’essai dans l’EN 16637 2 n’est pas appropriée pour les essais de ces produits de construction (dans ce cas, l’EN 16105[8] peut être une méthode alternative).
Gradbeni proizvodi - Ocenjevanje sproščanja nevarnih snovi - 1. del: Navodilo za določanje preskusov izluževanja in dodatnih korakov preskušanja
(1) Ta evropski standard omogoča opredelitev ustrezne preskusne metode izluževanja za določanje sproščanja reguliranih nevarnih snovi (RDS) iz gradbenih proizvodov v tla, površinsko vodo in podtalnico. Ta dokument določa korake postopka za določanje ustreznih preskusov sproščanja, vključno z:
a) določanjem preskusne metode na podlagi splošnih lastnosti proizvodov;
b) izbiro preskusne metode z uporabo posebnih lastnosti proizvodov.
(2) Poleg tega ta evropski standard določa splošna navodila za tehnične odbore za proizvode CEN in delovne skupine EOTA v zvezi z osnovnimi vidiki (vzorčenje, priprava vzorcev in shramba, obdelava izlužkov, analiza izlužkov in dokumentacija), ki se določijo v ustreznih standardih za proizvode ali evropskih tehničnih soglasjih ETA.
(3) Kovinski proizvodi in premazi na kovinskih proizvodih niso obravnavani v shemi določanja te tehnične specifikacije, saj preskusne metode iz standarda EN 16637-2 (preskus s cisterno) in EN 16637-3 (preskus v stolpcu) niso primerne za preskušanje teh gradbenih proizvodov zaradi drugačnega mehanizma sproščanja (nadzor topljivosti).
OPOMBA: glej dodatek F.
4) Domneva se, da je občasen stik z vodo (npr. izpostavljenost deževnici) preskušen – po dogovoru – kot stalen stik.
Pri nekaterih premazih (npr. nekateri ometi z organskimi vezivi v skladu s standardom EN 15824 [4]) v občasnem stiku z vodo se lahko fizikalne in kemijske lastnosti spremenijo ob stalnem stiku z vodo. Ti proizvodi niso obravnavani v shemi določanja te tehnične specifikacije, saj preskusna metoda iz standarda EN 16637-2 ni primerna za preskušanje teh gradbenih proizvodov (v tem primeru je lahko standard EN 16105 alternativna metoda).

Introduction
The European Standards EN 16637-1, EN 16637-2 and EN 16637-3 are developed to assess the release
of regulated dangerous substances (RDS) from construction products into soil, surface water and
groundwater in the framework of Mandate M/366. The horizontal test methods developed under the
Mandate M/366 are intended to be used to show compliance with notified regulations. The tests cover
the release of substances from construction products and in particular, those that are regulated in
notified regulations in one or more EU Member States.
EN 16637-1 specifies how the CEN Technical Product Committees and EOTA experts should determine
the appropriate leaching test for the determination of the release of RDS from a construction product into
soil, surface water and groundwater. EN 16637-1 gives background information for CEN Technical
Product Committees on the following aspects:
— description of the intended conditions of use of the construction product (e.g. above ground exposed
to the precipitation, or shielded from direct infiltration, in surface or groundwater) with respect to
the release of RDS into soil, surface water and groundwater;
— identification of main release mechanisms, and the appropriate leaching test for a given construction
product.
EN 16637-2 specifies a horizontal test to assess surface dependent release from monolithic, plate-like or
sheet-like construction products (tank test).
EN 16637-3 specifies a horizontal test to assess release from granular construction products.
The test methods can be used for both steps in the hierarchy (type testing (TT) and factory production
control (FPC)) and form the reference tests for the intended uses and conditions specified in EN 16637-1.
In this hierarchy of testing conditionally “indirect
