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 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 document specifies the apparatus and analytical method for determining the content of in-can isothiazolinone preservatives in water-dilutable coating materials or related products.
Note   The document is also applicable for polymer dispersions.

The method describes the quantitative determination of the in-can total formaldehyde content in water-dilutable coating materials. Main sources of formaldehyde are preservatives.
NOTE: The standard is also applicable for polymer dispersions.

The method describes the quantitative determination of the concentration of in-can free formaldehyde in water-dilutable coating materials.
Note: The standard can also be applied for polymer dispersions.
The determination method for in-can free formaldehyde can be only of limited suitability for pigmented systems, as the inherent coloration of the material may have an influence on the detection method.

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.
Safety, health and environmental aspects are not in the scope of this standard.

This European Standard 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.
