ASTM G21-15 pdf can be downloaded here.The title of the standard is Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi.
ASTM G21-15 covers determination of the effect of fungi on the properties of synthetic polymeric materials in the form of molded and fabricated articles, tubes, rods, sheets, and film materials.
The procedure described in this practice consists of selection of suitable specimens for determination of pertinent properties, inoculation of the specimens with suitable organisms, exposure of inoculated specimens under conditions favorable to growth, examination and rating for visual growth.and removal of the specimens and observations for testing,either before cleaning or after cleaning and reconditioning.
NOTE 1:Since the procedure involves handling and working with fungi, it is recommended that personnel trained in microbiology performthe portion of the procedure involving handling of organisms and inoculated specimens.
