Scope:
1.1 This Standard provides an evaluation method for
assessing the resistance of surfaces of wood products,
treated or untreated, coated or uncoated, to the growth of
molds. The main objective of the method is to determine
the relative resistance of wood products to surface growth
of molds in an environment favorable for growth of fungi.
Resistance to mold growth is evaluated relative to reference
products and unprotected sapwood of a species of pine.
Pine sapwood is included as an untreated control substrate
to indicate viability of molds in the test chamber and
severity of growth conditions. This test method may also be
used to evaluate compounds or formulations that may
inhibit fungal growth and the aggregate levels for their use.
Products evaluated with this method would be intended for
use in interior environments where the products may be
unintentionally subjected to conditions favorable to the
growth of molds. This Standard is based on the ASTM
Standard Test Method D 3273-00, Standard Test Method
for Resistance to Growth of Mold on the Surface of Interior
Coatings in an Environmental Chamber. This test method
is intended to be a screening test.
1.2 The method is applicable to the testing of commercial
or experimental wood products designed to be resistant to
the growth of molds. Performance at a certain rating does
not imply any specific period of time for a fungal free
surface in service, however products with a better rating
would likely perform better in actual end use.
