AATCC 30-III Testing

Assessing the antifungal activity, mildew and rot resistance of textile and polymer materials.

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
