What is BS EN 15458 – Method for testing the efficacy of film preservatives in a coating against algae about?
BS EN 15458 discusses paints and varnishes. BS EN 15458 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 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. BS EN 15457 helps to determine the effectiveness of film preservatives against algae in the coatings.
Note1: BS EN 15458 does not apply to coatings not susceptible to algal growth.
Note2: BS EN 15458 not applicable to marine coatings.
Note3: Safety, health and environmental aspects are not in the scope of BS EN 15458.
Note4: Determination of the performance of film preservatives in coatings by applying ageing procedures is not within the scope of BS EN 15458.
Who is BS EN 15458 – Method for testing the efficacy of film preservatives in a coating against algae for?
BS EN 15458 on paints and varnishes is useful for:
- Paint manufacturers
- Preservatives manufacturers
- Civil engineers
- Architectures
- Regulatory bodies
Why should you use BS EN 15458 – Method for testing the efficacy of film preservatives in a coating against algae?
Biocides are used in formulations to keep bacteria from spoiling paint during storage or to keep fungi, algae, and other micro-organisms from growing on the applied paint. BS EN 15458 provides test method to assess efficacy of film preservatives in a coating against algae. This will ensure that you product has the capability of protecting from the algae.
