Antimicrobial Testing

Antimicrobial testing is used to determine the efficacy of antimicrobial additives or inherent antimicrobial properties of a given material or product. Testing is key to cost containment and market acceptance.

As a product test laboratory, Situ Biosciences tests finished products for antimicrobial efficacy according to where and how the product is intended to be used. Preservation challenges, shelf life, and durability are a few of the considerations to make when selecting the relevant antimicrobial test for a specific product or industry.

Options include testing formulations to determine concentration levels, discovering new uses for existing antimicrobials, and testing products and applications using representative and actual pilot scale environmental conditions.

There are hundreds of methods used to test antimicrobials. Knowing which ones to use and why can help reduce the cost/time to get the product to market. Commonly used antimicrobial tests include AATCC 100 for textiles, AATCC 30-III for textiles and foam, ASTM E1259 for fuels, and ISO 22196 for plastics and coated materials.

Antimicrobial testing can become a vital part of a product’s Quality Control program and can be utilized throughout the stages of product development, or when a finished product has already hit the market for sale.

Determining the Correct Antimicrobial Test Method

Many of the methods used for antimicrobial testing are derived from Trade Organizations such as ASTM Antimicrobial Test Methods, AATCC Antimicrobial Test Methods, and ISO Antimicrobial Test Methods.  In addition to these organizations, other methods based on sound science or regulatory requirements (such as FDA Antimicrobial Test Methods or EPA Antimicrobial Test Methods) can be used.
