BS EN 4159 discusses paints and varnishes. The aim of BS EN 4159 is to provide the best industrial practice to determine the resistance of paints and varnishes to microbial growth. BS EN 4159 specifies a method to assess the ability of biocide-containing coatings to prevent the germination of conidiospores of certain fungi known to be capable of proliferating in fuel systems for aerospace applications.
BS EN 4159 on resistance of coating against microbial growth is useful for:
Certain fungi are known to be capable of proliferating in fuel systems which can cause corrosion and blockage. Conidiospores are the dispersal form of these fungi. Germination of conidia is the first stage in the proliferation of the fungus. If the conidiospore cannot germinate, there can be no proliferation and no blockage of fuel lines, ducts etc. When it comes to the manufacturing of paints and varnishes used in aerospace applications, reliability, consistent performance, and durability are crucial.
BS EN 4159 provides principle, apparatus, and procedure, to assess the efficacy of coating against fungi. This can help to assess the effectiveness of your new candidate coating systems in inhibiting microbial (fungal) growth.EN 4159:2011
