Paints and varnishes - Laboratory method for determination of release of regulated dangerous substances from coatings in intermittent contact with water

This document specifies a laboratory method to determine the leaching behaviour of substances from coatings into water over defined time intervals.
The release of substances from coatings under natural conditions cannot be determined with this method.
This method can be applied to renders, when condition (4) of the Scope of CEN/TS 16637-1 is fulfilled.
(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) in intermittent contact to water, physical and chemical properties might be altered in permanent contact with water. These products are not covered by the Technical Specification CEN/TS 16637-1 since the test method in CEN/TS 16637-2 is not appropriate for these construction products.

Beschichtungsstoffe - Laborverfahren zur Bestimmung der Freisetzung von Substanzen aus Beschichtungen in intermittierendem Kontakt mit Wasser

Dieses Dokument legt ein Laborverfahren fest, mit dem das Auswaschverhalten von Substanzen aus Beschichtungen ins Wasser innerhalb definierter Zeitintervalle bestimmt werden kann.
Das Verfahren ist für die Bestimmung des Auswaschens von Substanzen aus Beschichtungen unter natürlichen Bedingungen nicht anwendbar.
Dieses Verfahren kann für Putze angewendet werden, wenn die Bedingung (4) im Anwendungsbereich von CEN/TS 16637 1 erfüllt ist.
(4) Es wird angenommen, dass der zeitweilige Kontakt mit Wasser (zum Beispiel Beanspruchung durch Regenwasser) nach Vereinbarung als dauerhafter Kontakt geprüft wird. Bei einigen Beschichtungen (zum Beispiel einige Putze mit organischen Bindemitteln nach EN 15824), die zeitweilig mit Wasser in Berührung kommen, könnten sich bei dauerhaftem Kontakt mit Wasser physikalische und chemische Eigenschaften verändern. Diese Produkte werden nicht durch die Technische Spezifikation CEN/TS 16637 1 abgedeckt, da das Prüfverfahren in CEN/TS 16637 2 für diese Bauprodukte nicht geeignet ist.

Peintures et vernis - Méthode de laboratoire pour la détermination de la libération de substances dangereuses réglementées provenant de revêtements en contact avec l’eau par intermittence

Le présent document spécifie une méthode de laboratoire visant à déterminer le comportement à la lixiviation par l’eau des substances contenues dans les revêtements sur des intervalles de temps spécifiés.
La libération de substances depuis les revêtements dans des conditions naturelles ne peut pas être déterminée à l’aide de la présente méthode.
Cette méthode peut être appliquée aux enduits, lorsque la condition (4) du domaine d’application de la spécification technique CEN/TS 16637-1 est remplie.
(4) Il est supposé qu’un contact avec l’eau par intermittence (par exemple une exposition à l’eau de pluie) est soumis à essai — par convention — comme un contact permanent. Pour certains revêtements (par exemple certains enduits à base de liants organiques conformément à l’EN 15824) en contact avec l’eau par intermittence, les propriétés physiques et chimiques pourraient être altérées par un contact permanent avec l’eau. Ces produits ne sont pas couverts par la spécification technique CEN/TS 16637-1 car la méthode d’essai décrite dans la CEN/TS 16637-2 n’est pas appropriée pour ces produits de construction.

and Vanishes” the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16105:2011.

Introduction

Leaching of substances from coatings into water needs to be quantified to enable an environmental risk

assessment for the use of substances in coating materials. Substances can be leached from coatings,

particularly by driving rain, and transferred into the environment.

1 Scope

This document specifies a laboratory method to determine the leaching behaviour of substances from

coatings into water over defined time intervals.

The release of substances from coatings under natural conditions cannot be determined with this

method.

This methods can be applied to renders, when condition (4) of the scope of CEN/TS 16637-1 is fulfilled.

(4) It is assumed that the temporary contact with water (e.g. exposure to rainwater) is examined as a

permanent contact by agreement. For some coatings (e.g. some plasters with organic binders according

to EN 15824) that come into temporary contact with water, physical and chemical properties may

change with prolonged contact with water. These products are not covered in this Technical

Specification because the test method in CEN/TS 16637-2 is not suitable for testing these construction

products.
