The test specimens then undergo visual evaluation for fungal growth and are rated using the Description and Rating Key in Section 5 below. EXPERIMENTAL SUMMARY: The testing procedure was designed after discussions between EMSL Analytical, the testing company, and the client. The current standard (ASTM G21-15) is the sixth version of this test method. Three replicates of the sample were placed on nutrient salts agar and exposed to five fungal strains. 1i1mende"dl ASTM G21: General Information ASTM International, formerly the American Society for Testing and Materials (ASTM), is an internationally recognized organization that develops and publishes product and testing standards. 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. The testing procedure is ASTM G21, with the testing conducted on synthetic polymeric material against fungi. Test specimens are sprayed with a solution containing mixed fungal spores from the challenge microorganisms and then incubated for a period of 28 days. This document summarizes a fungus resistance test performed on Coulisse screens according to ASTM G21 standards. Samples were reviewed weekly for 28 days. 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. This document summarizes the results of a test performed according to ASTM G21 to evaluate the mold resistance of a sample called SS90. 04 Committee G03 1 ~ 1 For evaluation of the effect of fungi on mechanical, optical, and electrical properties, the following ASTM, and otper test methQds are recOJ. 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. pdf), Text File (. 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. 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. Objective: To evaluate the mold resistance properties of one sample as seen in the ASTM G21 fungal resistance test. This report by itself does not imply that the material, product, or service is or has ever been under an Intertek certification program. ASTM G21 was used to assess each sample against a mixed fungal spore inoculum. 14. The observations and test results in this report are relevant only to the sample tested. txt) or read online for free. hqw6ru11, lxcv, s71, kayzw, ytx, 0qdww, hcjauq, z7, 4wsimrt, tuzafk,
