BS 1982-3:1990

This standard BS 1982-3:1990 Fungal resistance of panel products made of or containing materials of organic origin is classified in these ICS categories:

• 79.020 Wood technology processes
• 79.060.01 Wood-based panels in general

This Part of BS 1982 describes two methods of test for the determination of the resistance of panel products to the growth of surface mould or mildew.

The methods are applicable in particular to building materials required to present a decorative finish including particleboard, plywood and plasterboard.

Method L is applicable to situations where the material is exposed to high humidity conditions but without wetting from liquid water (low moisture) and method H is applicable to situations where the material is exposed to direct wetting (high moisture) for prolonged periods.

The tests described are also applicable to products that have received a preservative treatment.

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

The extent of surface mould growth is assessed and classified after exposure either under conditions of direct wetting or without direct wetting.
