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 Technical Specification 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 Technical Specification since the test methods in CEN/TS 16637-2 (tank test) and CEN/TS 16637-3 (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 [4]) 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 Technical Specification since the test method in CEN/TS 16637-2 is not appropriate for the testing of these construction products (in this case EN 16105 [5] might be an alternative method).
Bauprodukte - Bewertung der Freisetzung von gefährlichen Stoffen - Teil 1: Leitfaden für die Festlegung von Auslaugprüfungen und zusätzlichen Prüfschritten
(1) 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. Das vorliegende 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.
(2) Darüber hinaus enthält diese Technische Spezifikation einen Leitfaden für die Technischen Produktkomitees des CEN und Arbeitsgruppen (WG) der Europäische 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.
(3) Metallische Produkte und Beschichtungen auf metallischen Produkten werden in dieser Technischen Spezifikation nicht berücksichtigt, da die Prüfverfahren in CEN/TS 16637-2 (Trog-Prüfverfahren) und CEN/TS 16637-3 (Perkolationsprüfung) für die Prüfung dieser Bauprodukte aufgrund eines anderen Freisetzungsmechanismus (Löslichkeitssteuerung) nicht geeignet sind.
ANMERKUNG Siehe Anhang F.
(4) 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 [4]), die zeitweilig mit Wasser in Berührung kommen, könnten physikalische und chemische Eigenschaften sich bei dauerhaftem Kontakt mit Wasser ändern. Diese Produkte werden nicht in dieser Technischen Spezifikation berücksichtigt, da das Prüfverfahren in CEN/TS 16637-2 für die Prüfung dieser Bauprodukte nicht geeignet ist. (In diesem Fall könnte EN 16105 [5] ein geeignetes alternatives Prüfverfahren sein.]

Gradbeni proizvodi - Ocenjevanje sproščanja nevarnih snovi - 1. del: Navodilo za določanje preskusov izluževanja in dodatnih korakov preskušanja
(1) Ta tehnična specifikacija 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 tehnična specifikacija 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 specifikacij CEN/TS 16637 2 (preskus s cisterno) in CEN/TS 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 specifikacije CEN/TS 16637 2 ni primerna za preskušanje teh gradbenih proizvodov (v tem primeru je lahko standard EN 16105 [5] alternativna metoda).
