FCBA-BIO-M-006, Screening test of Bravery

The various methods aim to carry out rapid tests for initial screening of treatment products or materials. These are orientation tests used to determine an initial range of potentially effective concentrations for a new treatment. This type of test is also used to assess the durability (resistance) potential of new materials against rot fungi.

The Bravery screening test is a rapid orientation test designed to assess the potential effectiveness of a preservative product against basidiomycete fungi. The treated wood test tubes are exposed to basidiomycete fungi for 6 weeks. At the end of the test, the mass losses of the samples are compared with the mass losses of untreated wood, which makes it possible to assess the potential effectiveness of an innovative treatment or a range of concentrations of a wood treatment product against rot fungi.

The FCBA-BIO-M-006 method aims to assess the potential resistance of wood or composite materials to lignivorous basidiomycete fungi in a shorter time frame than EN 113 or the CEN/TS15083-2 method.

The wood or material samples are exposed to basidiomycete fungi for 6 weeks. At the end of the test, the mass losses of the samples are compared with the mass losses of reference species of known durability. This is a preliminary step (which does not replace EN113 or CEN TS/15083-2) enabling the manufacturer to obtain preliminary results on the material’s resistance to wood-destroying fungi compared to reference species or materials.
