"This method determines the resistance of textile materials to disfiguration by growth of fungi that derive their assimilable carbon not from the pure textile fibres but from nonfibrous substances present in or on the fibres. Under normal conditions of use, suitable nonfibrous sources of carbon are usually present on most textiles materials, e.g., applied finishing agents, natural constituents of raw cellulosic fibres, or contaminants. Therefore, to possess resistance to surface-growing fungi under damp or humid conditions, textile materials normally require treatment with a fungicide. This method evaluates the efficacy of the fungicidal treatment"--Purpose and Scope.
