ASTM C1338
Standard Test Method for
Determining Fungi Resistance of Insulation Materials and
Facings
This test method covers the determination of the ability of new insulation materials and their facings to support fungal growth.
Five different fungi are inoculated to the test samples and under laboratory controlled conditions favorable for the growth of mold, support or ressistance of sample to the fungi is studies over period of 28 days.
