ASTM D3273-12, “Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber,” has just been released and is available from Document Center Inc. This standard is an accelerated test for determining the resistance of interior coatings to mold growth. It is used by the building products industry to test the performance of their products with regards to mold and fungus.
ASTM D3273 is useful in estimating the performance of coatings designed for use in interior environments that promote mold growth and in evaluating compounds that may inhibit such growth and the aggregate levels for their use. It should preferably be used by persons who have had basic microbiological training.
This 8-page test method describes a small environmental chamber and the conditions of operation to evaluate reproducibly in a 4-week period the relative resistance of paint films to surface mold fungi and mildew growth in a severe interior environment. The apparatus is designed so it can be easily built or obtained by any interested party and will duplicate results obtained in a large tropical chamber.
