Construction products - Assessment of release of dangerous substances - Part 2: Horizontal dynamic surface leaching test
(1) This Technical Specification specifies a Dynamic Surface Leaching Test (DSLT) which is aimed at determining the release per unit surface area as a function of time of inorganic and/or non-volatile organic substances from a monolithic, plate- or sheet-like product, when it is put into contact with an aqueous solution (leachant). The test method is not suitable for substances that are volatile under ambient conditions.
(2) This test is a parameter specific test focusing on identifying and specifying parameter specific properties tested under specified conditions. It is not aimed at simulating real situations. The application of results to specific intended conditions of use may be established by means of modelling (not included in this Technical Specification).
(3) The modification for granular construction products with low hydraulic conductivity (Annex A) applies for granular particles with so little drainage capacity between the grains that percolation in percolation tests and in practice is nearly impossible.
(4) The test method applies to more or less regularly shaped test portions consisting of monolithic test pieces with minimum dimensions of 40 mm in all directions (volume > 64 000 mm3 (64 cm3)). It also applies to plate- or sheet-like products with surface areas of minimum 10 000 mm2 (100 cm2) exposed to the leachant. Products designed to drain water (e.g. draining tiles, porous asphalt) and monolithic granular products according to CEN/TS 16637-1:2014, Table 1, are also tested by this test method. All products to be tested are assumed to maintain their integrity over a time frame relevant for the considered intended use.
(5) Metals, metallic coatings and organic coatings on metals are excluded from the scope of CEN/TS 16637-2 because the principles of this test (diffusion) are not obeyed by these products. Guidance on the need for testing of these products is under consideration.
(6) For some coatings (e.g. some renders with organic binders according to EN 15824) in intermittent contact to water, physical and chemical properties might be changed in permanent contact with water. For these products CEN/TS 16637-2 is not appropriate.
(7) Guidance on the applicability of the test method to a given product is outlined in CEN/TS 16637-1.
NOTE 1 This test method is only applicable if the product is chemically stable and the matrix does not dissolve. For construction products that may be used in contact with water this usually should not be the case as construction products should then be dimensionally stable. If a product may substantially wear in its intended use, the test cannot provide proper information. If the product contains a substantial amount of water-soluble compounds, e.g. gypsum or anhydrite, the matrix may (partially) dissolve and lead to dimensional instability of the test piece. In this case the test standard also cannot be used.
NOTE 2 Volatile organic substances include the low molecular weight substances in mixtures such as mineral oil.
NOTE 3 It is not always possible to optimise test conditions simultaneously for inorganic and organic substances and optimum test conditions may also vary between different groups of organic substances. Test requirements for organic substances are generally more stringent than those for inorganic substances. The test conditions suitable for measuring the release of organic substances will generally also be applicable to inorganic substances.
Bauprodukte - Bewertung der Freisetzung von gefährlichen Stoffen - Teil 2: Horizontale dynamische Oberflächenauslaugprüfung
(1) Diese Technische Spezifikation legt eine dynamische Oberflächenauslaugprüfung (DSLT) fest, welche der Bestimmung der Freisetzung von anorganischen und/oder nicht flüchtigen organischen Stoffen je Oberflächeneinheit aus einem monolithischen, platten- oder blattartigen Produkt in Abhängigkeit von der Zeit dient, wenn diese Bauprodukte mit einer wässrigen Lösung (Auslaugmittel) in Berührung kommen. Das Prüfverfahren ist für Stoffe, die unter Umgebungsbedingungen flüchtig sind, nicht geeignet.
(2) Diese Prüfung ist eine parameterspezifische Prüfung, die auf die Identifizierung und Festlegung von parameterspezifischen Eigenschaften, die unter festgelegten Bedingungen geprüft werden, gerichtet ist. Sie hat nicht zum Ziel, reale Situationen nachzubilden. Die Anwendung der Ergebnisse auf spezifische Bedingungen der vorgesehenen Verwendung kann mittels Modellierung erfolgen (nicht in dieser Technischen Spezifikation enthalten).
(3) Die Modifikation für körnige Bauprodukte mit geringer Durchlässigkeit (Anhang A) gilt für körnige Partikel mit einem so geringen Wasserableitvermögen zwischen den Körnern, dass die Perkolation in Perkolationsprüfungen und in der Praxis nahezu unmöglich ist.
(4) Das Prüfverfahren gilt für mehr oder weniger regelmäßig geformte Untersuchungsmengen, die aus monolithischen Prüfstücken mit Mindestabmessungen von 40 mm in allen Richtungen bestehen (Volumen 64 000 mm3 (64 cm3)). Es gilt ebenso für platten- oder blattartige Produkte mit dem Auslaugmittel ausgesetzten Oberflächen von mindestens 10 000 mm2 (100 cm2). Produkte, die zur Ableitung von Wasser entwickelt wurden (z. B. Traufenpflaster, Porenasphalt) sowie monolithische körnige Produkte nach FprCEN/TS 166371:2013, Tabelle 1, sind ebenfalls mit diesem Prüfverfahren zu prüfen. Bei allen zu prüfenden Produkten wird davon ausgegangen, dass sie über einen für die betrachtete vorgesehene Verwendung maßgeblichen Zeitrahmen unversehrt bleiben.
(5) Metalle, metallische Beschichtungen und organische Beschichtungen auf Metallen sind vom Anwendungsbereich der FprCEN/TS 16637-2 ausgenommen, da die Grundsätze dieser Prüfung (Diffusion) von diesen Produkten nicht befolgt werden. Ein Leitfaden über die Notwendigkeit der Prüfung dieser Produkte steht zur Diskussion.
(6) Bei einigen Beschichtungen (z. B. einige Putze mit organischen Bindemitteln nach EN 15824), die zeitweilig mit Wasser in Berührung kommen, könnten physikalische und chemische Eigenschaften zu dauerhaftem Kontakt mit Wasser geändert werden. Für diese Produkte ist FprCEN/TS 16637-2 nicht geeignet.
(7) Eine Anleitung zur Anwendbarkeit des Prüfverfahrens für ein bestimmtes Produkt ist in FprCEN/TS 16637-1 enthalten.
ANMERKUNG 1 Dieses Prüfverfahren ist nur dann anwendbar, wenn das Produkt chemisch beständig ist und die Matrix sich nicht auflöst. Bei Bauprodukten, die bei ihrer Verwendung möglicherweise mit Wasser in Berührung kommen, sollte das üblicherweise nicht der Fall sein, da solche Bauprodukte maßbeständig sein sollten. Wenn ein Produkt bei seiner vorgesehenen Verwendung im beträchtlichen Maße abgenutzt werden kann, kann die Prüfung keine angemessenen Informationen liefern. Wenn das Produkt eine erhebliche Menge wasserlöslicher Verbindungen enthält, z. B. Gips oder Anhydrit, ist eine (teilweise) Auflösung der Matrix möglich, was zu einer maßlichen Unbeständigkeit des Prüfstücks führt. In diesem Fall kann die Prüfnorm ebenfalls nicht angewendet werden.
ANMERKUNG 2 Flüchtige organische Stoffe schließen die in Gemischen wie z. B. Mineralöl enthaltenen Stoffe mit geringem Molekulargewicht ein.
ANMERKUNG 3 Es ist nicht immer möglich, die Prüfbedingungen gleichzeitig für anorganische und organische Stoffe zu optimieren, und die optimalen Prüfbedingungen können auch zwischen verschiedenen Gruppen organischer Stoffe verschieden sein.

Gradbeni proizvodi - Ocenjevanje sproščanja nevarnih snovi - 2. del: Horizontalni dinamični preskus za izluževanje s površine
Specifikacija CEN/TS 16637-2 določa dinamični preskus za izluževanje s površine (DSLT), ki je namenjen določanju sproščanja na enoto površine kot funkcija časa anorganskih in/ali nehlapnih organskih snovi iz monolitnega proizvoda ali proizvoda v obliki plošče ali traku, kadar pride v stik z vodno raztopino (izluževalni medij). Preskusna metoda ni primerna za snovi, ki so hlapne pri okoljskih pogojih. (2) Ta preskus je preskus z določenimi parametri s poudarkom na opredelitvi in določanju lastnosti z določenimi parametri, preskušenih pod določenimi pogoji. Ni namenjen posnemanju resničnih razmer. Uporaba rezultatov za posebne nameravane pogoje uporabe se lahko določi z modeliranjem (ni vključeno v to tehnično specifikacijo). (3) Sprememba za zrnate gradbene proizvode z nizko hidravlično prevodnostjo (Dodatek A) se uporablja za zrnate delce s tako majhno zmogljivostjo odvodnjavanja med zrnci, da je precejanje pri preskusih precejanja in v praksi skoraj nemogoče. (4) Preskusna metoda se uporablja za bolj ali manj običajno oblikovane preskusne dele, ki jih sestavljajo monolitni preskusni delci z najmanjšimi merami 40 mm v vseh smereh (prostornina > 64000 mm3 (64 cm3)). Uporablja se tudi za proizvode v obliki plošče ali traku s površino najmanj 10000 mm2 (100 cm2), izpostavljene izluževalnemu mediju. Proizvodi, oblikovani za prepuščanje vode (npr. ploščice za odvodnjavanje, porozni asfalt) in monolitni zrnati proizvodi v skladu s preglednico 1 specifikacije CEN/TS 16637-1:2014 se prav tako preskusijo s to preskusno metodo. Predvideva se, da vsi proizvodi, ki se preskusijo, ohranijo svojo integriteto v časovnem okviru, ustreznem za obravnavano predvideno uporabo. (5) Kovine, kovinski premazi in organski premazi za kovine so izključeni iz obsega specifikacije CEN/TS 16637-2, ker ti proizvodi ne upoštevajo načel tega preskusa (difuzija). Navodila za potrebo po preskušanju teh proizvodov se pripravljajo. (6) Pri nekaterih premazih (npr. nekateri ometi z organskimi vezivi v skladu s standardom EN 15824) v občasnem stiku z vodo se lahko fizikalne in kemijske lastnosti spremenijo ob stalnem stiku z vodo. Specifikacija CEN/TS 16637-2 ni primerna za te proizvode. (7) Navodila za uporabnost preskusne metode za določen proizvod so podana v specifikaciji CEN/TS 16637-1.

Introduction
The informative introduction describes the interactions and interrelations between the three Technical
Specifications CEN/TS 16637-1, CEN/TS 16637-2 and FprCEN/TS 16637-3 (in preparation) developed to
assess the release of dangerous substances from construction products into soil, surface water and ground
water in the framework of the 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.
CEN/TS 16637-1 specifies how the CEN Technical Product Committees and EOTA experts are to determine
the appropriate release method for the determination of the release of Regulated Dangerous Substances from
a construction product into soil, surface water and groundwater.
