NBN EN 15458:2007

This European standard specifies a laboratory test method for determining the biocidal/biostatic efficacy of 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 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 wood and masonry coatings. It is not applicable to marine coatings.
Safety, health and environmental aspects are not in the scope of this standard.
