CEN/TC 139/WG 10 - Laboratory methods for testing the efficacy of film preservatives according tothe requirements of the biocide product directive (BPD)

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.

This document specifies a laboratory test method for determining the biocidal or biostatic efficacy of single active substances or combinations thereof used in film preservatives of coatings against algal growth. The document does not apply to coatings unsusceptible to algal growth. The test method covers only active substances for film preservation, not the substrate itself, e.g. wood, which is dealt with in another standard. The test method is applicable for active substances used for wood protection and masonry coatings. It is not applicable to marine coatings.
Safety, health and environmental aspects are not in the scope of this document.
Determination of the performance of film preservatives in coatings by applying ageing procedures is not within the scope of this document.

This document specifies a laboratory test method for determining the biocidal or biostatic efficacy of single active substances or combinations thereof used in film preservatives of coatings against fungal growth. This document does not apply to coatings unsusceptible to fungal growth. The test method covers only active substances for film preservation. It does not indicate the efficacy of the coating film to protect itself or an underlying material. The test method is applicable for active substances used for the protection of wood and masonry coatings. It is not applicable to marine coatings.
Safety, health and environmental aspects are not in the scope of this document.
Determination of the performance of film preservatives in coatings by applying ageing procedures is not within the scope of this document.

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 fungal growth. This standard does not apply to coatings not susceptible to fungal 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.
