Description

This Method specifies the procedure for determining the resistance of seasoned timber, including composite materials containing timber (including plywood, particleboard and cellulose-wood fibre boards) to surface growing fungi. These fungi may not physically weaken the timber or cause deep staining, but are objectionable for aesthetic reasons or for their adverse effect on surface properties.

Timbers to be tested according to this Method include treated or untreated timbers in the hazard class H2 (inside, above ground, protected from wetting and nil leaching) and hazard class H3 (outside, above ground, subject to periodic moderate wetting and leaching), as in AS 1604.

This Standard provides a laboratory test which is intended to provide severe, standardized assessment of fungal resistance under laboratory conditions. It does not include the testing of timber in the field which, although possibly more severe, is much longer in duration and also more subjective.
