This Part of BS 3900 describes a method for assessing the fungal (mould) resistance of paints, varnishes and lacquers with or without fungicidal additives, applied either as part of a multi-coat system or separately.

In addition to the information given in the method certain supplementary information detailed in clause 3 is necessary before this method can be used.

WARNING When carrying out this method it is essential to avoid inhalation of spores by the operator and contamination by the spores of the laboratory. Guidance on precautions is given in Appendix A and attention is drawn to BS 2011-2.2J for more detailed advice.

NOTE 1 The method has been prepared to assess the resistance to fungal growth of paints applied in the laboratory to specified panels. The principle may also be applied to production applied coatings on sheet materials having established a criterion for assessment but a claim to comply with this Part of BS 3900 cannot be made.

NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
