Jan. 31, 2011 - PRLog -- Situ Biosciences are microbiological test experts providing expertise for the design, development, and laboratory testing of microbial performance as required for antifungal or fungal remediation technologies.

Antifungal products are those designed to provide resistance to the growth or effects of fungi, including mold and mildew.  The range of products that should be treated with an antifungal is extensive and can include the components of raw materials, formulation additives, or the ultimate finished product.

Many product types use antifungal additives; common examples include paper or paper compositions, electronics and electrical insulation or coatings, textiles and leathers, plastics and resins and their respective end product compositions. Depending on the use environment or performance desired by the product, different amounts and types of antifungal additives could be used.

Knowing which components need to be treated, and how to treat them is half of the battle, getting accurate reproducible test results can simplify the development process, cutting cost and development time.

The "microbe rule of 3"  provides guidance on whether or not fungi will begin to grow on a given material.  For product developers, how to best optimize their products will depend on the product development process and implementation of an appropriate testing strategy.
There are many test methods used to make this assessment, but the most common methods used in North America are those provided by the American Society for Testing and Materials (ASTM).  ASTM provides a standardized series of test methods that are rigorously updated and harmonized for global applicability.

For our laboratory, the most frequently requested test methods include the ASTM G 21, ASTM D 3273, and ASTM D 5590.  These antifungal test methods are targeted at specific product types (such as coatings for ASTM G21 or ASTM D5590, or drywall for ASTM D 3273), but are also used as standards in the development of a wide range of antifungal products.

ASTM G 21 -- Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi –  
ASTM D 5590 -- Determining the Resistance of Paint Films and Related Coatings to Fungal Defacement by Accelerated Four-Week Agar Plate Assay  -
ASTM D 3273 -- Standard Test Method for Resistance to Mold on the Surface of Interior Coatings in an Environmental Chamber –

Other methods commonly requested on a more seasonal basis are textile methods, principally for antifungal preservation of bulk textiles and other specialty applications such as medical and outdoor textiles.  The test methods used by Situ Biosciences for antifungal textiles include AATCC TM 30 and AATCC TM 174 and also ASTM methods or related methods specially developed for our customers that provide additional testing for textile durability or product performance and odor control.

AATCC 174 Antimicrobial Activity Assessment of Carpets

Situ Biosciences provides data tracking and ISO compliance for our testing and environmental chambers used in Military Standard testing of finished products, electrical components, textiles and items requiring ruggedness evaluations.   For ruggednes testing, the principle test method at our laboratory is the MIL-STD 810g for fungi but other international methods are tested for their compliance at our facility.
