Paints and varnishes - Laboratory method for testing the efficacy of film preservatives in a coating against algae
This European Standard specifies a laboratory test method for determining the biocidal/biostatic efficacy of single active substances or combinations thereof used in film preservatives in a coating against algal growth. The standard does not apply to coatings not susceptible to algal growth. The test method comprises only active substances for film preservation, not the protection of the substrate itself, e.g. wood, which is dealt with in another standard. The test method is applicable for active substances used for wood and masonry coatings. It is not applicable to marine coatings.
Safety, health and environmental aspects are not in the scope of this standard.
Determination of the performance of film preservatives in coatings by applying ageing procedures is not within the scope of this standard.
Beschichtungsstoffe - Laborverfahren für die Prüfung der Wirksamkeit von Filmkonservierungsmitteln in einer Beschichtung gegen Algen
Dieses Dokument legt ein Laborverfahren zum Bestimmen der bioziden/biostatischen Wirksamkeit von Wirkstoffen oder einer Kombination aus mehreren Wirkstoffen zur Anwendung in Filmkonservierungsmitteln in Beschichtungen gegen Algenbewuchs fest. Dieses Dokument gilt nicht für Beschichtungen, die unempfindlich gegen Algenbewuchs sind. Das Prüfverfahren deckt nur die Wirkstoffe zur Filmkonservierung der Beschichtung ab, nicht zum Schutz des Substrats, z. B. Holz. Dieser wird in einer anderen Norm behandelt. Das Prüfverfahren ist anwendbar für Wirkstoffe, die in Beschichtungen für den Schutz von Holz und für mineralische Substrate verwendet werden. Die Norm gilt nicht für Beschichtungen im maritimen Bereich.
Sicherheits-, Gesundheits- und Umweltaspekte liegen nicht im Anwendungsbereich dieses Dokuments.
Die Bestimmung der Wirksamkeit von Filmkonservierungsmitteln in Beschichtungen nach Anwendung von Alterungsverfahren liegt nicht im Anwendungsbereich dieses Dokuments.
Peintures et vernis - Méthode d'essai en laboratoire permettant de déterminer l'efficacité des préservateurs du feuil d'un revêtement contre les algues
Le présent document spécifie une méthode d’essai en laboratoire permettant de déterminer l’efficacité biocide ou biostatique de substances actives individuelles, ou de combinaisons de ces substances, utilisées dans les préservateurs du feuil de revêtements contre la prolifération d’algues. Ce document ne s’applique pas aux revêtements qui ne sont pas sensibles à la prolifération d’algues. Cette méthode d’essai concerne uniquement les substances actives utilisées pour la protection du feuil et non du subjectile lui même, par exemple le bois, laquelle fait l’objet d’une autre norme. Cette méthode d’essai est applicable aux substances actives utilisées pour la protection des peintures pour bois et pour maçonnerie. Elle ne s’applique pas aux peintures marines.
Les aspects de sécurité et de santé, ainsi que les aspects environnementaux, ne relèvent pas du domaine d’application du présent document.
La détermination des performances des produits de préservation du feuil de revêtements par des méthodes de vieillissement n’est pas traitée dans le présent document.
Barve in laki - Laboratorijska metoda za preskušanje učinkovitosti konzervansov filma v premazih proti algam
Ta evropski standard določa laboratorijsko preskusno metodo za določanje biocidne/biostatične učinkovitosti posamezne aktivne snovi ali kombinacij aktivnih snovi, ki se uporabljajo v konzervansih filma v premazih proti algam. Standard se ne uporablja za premaze, ki niso občutljivi na alge. Preskusna metoda vključuje samo aktivne snovi za ohranjanje filma in ne za zaščito same podlage, npr. lesa, ki jo obravnava drug standard. Preskusna metoda se uporablja za aktivne snovi, ki se uporabljajo za lesne in zidne premaze. Ne uporablja se za ladijske premaze.
Na področje uporabe tega standarda niso vključeni vidiki varnosti, zdravja in varstva okolja.
Določanje učinkovitosti konzervansov filma v premazih z izvajanjem postopkov staranja ne spada na področje uporabe tega standarda.

4 Principle
To determine the algicidal efficacy of film preservatives in a coating, the coating material is applied to a
substrate, conditioned according to EN 23270, placed onto an agar surface, inoculated with a standard
algal suspension and incubated over a certain period of time under conditions appropriate for algal
growth. Conclusions can be drawn with regard to the algicidal efficacy of the film preservatives in a
coating from the intensity of the algal growth on the coated surface of the test specimen after incubation.
The method described in this document is a semiquantitative, comparative method between coatings
with and without film preservatives.
