Loss of mass after partial burial in natural garden soil is used to determine the inherent resistance of panel products, the resistance conferred by preservative chemicals, or the comparative resistance of treated or untreated panel products.

This Part of BS 1982 describes a method for subjecting panel products to attack by cellulose-decomposing microfungi and assessing the significance of the results obtained.

The method is applicable to rigid sheet materials which do not disintegrate upon exposure to moisture alone. It is applicable to the determination of the inherent resistance of such panel products to attack by cellulose-decomposing microfungi or the resistance to such attack conferred by the use of preserving chemicals during manufacture or subsequently.

The method of test is designed solely to meet the above objectives and is not intended to simulate any form of conditions in service. The test results in themselves cannot be used directly to predict service life in practice.
