Mildew Fungistatic Test for Fabrics or Hard Surfaces
Purpose of Test
The Mildew Fungistatic Test method is used to evaluate the mildew resistance of treated ceramic tiles or fabrics. This method is generally used to substantiate non-public health related claims with the U.S. EPA.
Summary of Test
In this method, ceramic tile or cotton muslin carriers are treated with the product and the carriers are allowed to dry. Following drying, the carriers are inoculated with Aspergillus niger. The treated carriers are incubated in a high humidity environment and are visually rated for mold growth. For a product to be considered an effective mildew fungistat, the treated surfaces must demonstrate no mold growth following incubation.
