What Is AATCC 30-III?
AATCC 30-III is a qualitative test method used to determine the antifungal effectiveness of antimicrobial-treated textiles or polymers.
How Does AATCC 30-III Work?
The test uses a common environmental mold called Aspergillus niger.
Test samples are placed on nutritive agar plates covered with the test fungus. Samples are in contact with the fungus for a 7-day period. During this time, the fungus and samples are kept at 29°C and high humidity, which are optimal conditions for fungal growth.
Following the exposure time of fungus to the test material, the samples are examined to see if there is a fungal growth on the sample.
The Microban Standard: 0-3 Rating Scale
Test samples analysed under the AATCC 30-III antifungal test method are rated on a scale of 0-2. The rating is determined by the presence of fungal growth on the sample.
- Pass: Rating = 0 – no fungal growth on sample
- Fail: Rating = 1 – fungal growth that can be seen with microscope
- Fail: Rating = 2 – fungal growth that can be seen without microscope
