The USP <62> Test for Specified Microorganisms, like the USP <61>, is a product safety test from the United States Pharmacopeia. The USP <62> test evaluates a product for the presence or absence of potential pathogens. USP <62> tests are necessary for cosmetic and personal products to determine that any...
The MIL-STD-810G are a series of laboratory standards designed by the United States military to test the endurance capabilities of materials based on the expected field conditions they will meet during their lifetimes. Method 508.6 is a material fungal resistance test developed to determine if the material components comprising the...
Below, you will find a summary of the AOAC Germicidal Spray Products Test method, modified for use with fungi. The method is sometimes modified for use with fungi to support supplemental efficacy (fungicidal) label claims for pesticides registered with the United States Environmental Protection Agency. Trichophyton mentagtrophytes is the preferred test...
The ASTM D3273 method is meant to evaluate fungal defacement of coated interior surfaces in an accelerated manner. The ASTM D3273 test specifically aims to establish the relative resistance of paint films to the propagation of mold and mildew under optimum fungal growth conditions. Incubation occurs in a highly...
The ASTM D3274 Method details a standardized rating system designed to evaluate the degree of fungal resistance of surface coatings (e.g. paint films). This method is used for tests such as the ASTM D3273. Ratings are based on the percentage of surface fungal coverage and qualitative descriptions. While this...
Some materials may become discolored or stained when microorganisms grow on them in the environment. The ASTM E1428 standard is used to evaluate the ability of synthetic polymeric materials containing antimicrobial agents to resist such staining, using the indicator staining organism Streptoverticullium reticulum. The ASTM E1428 method is straightforward and...
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. It is a popular method, used by industry to evaluate the resistance...
The EN 1650 test method, titled "Chemical disinfectants and antiseptics - Quantitative suspension test for the evaluation of fungicidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic, and institutional areas", is a European Standard, used to determine the anti-fungal efficacy of chemical disinfectants and antiseptics used in...
Assessment of Antimicrobial Finishes on Carpet The American Association of Textile Chemists and Colorists (AATCC) 174 method, titled "Antimicrobial Activity Assessment of Carpets", is designed to test the antimicrobial activity of new carpet materials. Within the official standard method, there are 3 procedures – qualitative and quantitative assessments of the...
The AATCC 30 method, titled "Antifungal Activity, Assessment on Textile Materials: Mildew and Rot Resistance of Textile Materials" is designed to determine how susceptible textile materials (cloth, gauze, or similar objects) are to mildew and fungal growth and evaluate the efficacy of the fungicides applied to the selected materials. The...
Yeast and molds are types of fungal cells that can cause various degrees of deterioration and decomposition of cosmetics and personal care products. Since yeast and molds are ubiquitous (occurring everywhere) in nature just as bacteria are, cosmetics and personal care products are just as susceptible to fungal contamination...
This test is used to assess the fungicidal activity of a disinfectant. In this test, a typical fungus strain of Trichophyton mentagrophytes is cultured and resuspended in order to attain spore producing mycelium; however, the method can be modified to meet the needs of the study sponsor's requirements. The...
