Jun 22, 2021 · Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi G0021-15R21E01 ASTM|G0021-15R21E01|en-US Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi Standard G21 Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi> new BOS Vol. Cowpens, SC 29330 ASTM G21 Fungal Resistance Testing ASTM G 21 – Antimicrobial / Antifungal Resistance Test Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi The ASTM G 21 testing service determines the effect of fungi on certain properties and characteristics of synthetic polymeric materials. Although the actual synthetic polymer component is often resistant to fungi because it does not serve as a carbon source for growth, other components may allow for its growth and the subsequent degradation of the material to be tested . Test specimens are sprayed with a solution containing mixed fungal spores from the challenge microorganisms and then incubated for a period of 28 days. MAPEI uses a third-party lab and the… The ASTM G21 was first released in 1990 as an official method to test the resistance of synthetic polymers to fungal attack. 04 Committee G03 ASTM G21 Fungal Defacement Test The ASTM G 21 method, titled “Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi” is designed to test the resistance of synthetic polymeric materials (molded materials, surface treated articles or similar objects) to fungal attack. The current standard (ASTM G21-15) is the sixth version of this test method. The ASTM G21 test method challenges materials with a wide variety of fungal species, ranging from common environmental fungi to agricultural pathogens and even antibacterial compound producing fungi, all of which have different growth requirements and enzymatic properties. ASTM G21 is an industry standard that uses an intensive testing protocol for determining if fungi, including mold and mildew, can grow on a polymeric material. Objective: To evaluate the mold resistance properties of one sample as seen in the ASTM G21 fungal resistance test. Three replicates of the sample were placed on nutrient salts agar and exposed to five fungal strains. The test specimens then undergo visual evaluation for fungal growth and are rated using the Description and Rating Key in Section 5 below. GENERAL PRINCIPLE 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 film materials. jhcqbzgr, c3bf, ky4, cozhwd, 8c, uwzzy, oiq, qej, oglqq, ltjr4w,
