Designation: G 21 – 96 (Reapproved 2002) Standard Practice forDetermining Resistance of Synthetic Polymeric Materials to Fungi 1 This standard is issued under the ?xed designation G 21; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. Anumber in parentheses indicates the year of last reapproval. Asuperscript epsilon ( e) indicates an editorial change since the last revision or reapproval. 1. Scope This practice 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 ?lm materials. Changes in optical, mechanical, and electrical prop- erties may be determined by the applicable ASTM methods. The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use. 2.
