Defacement of paint and coating films by fungal growth mold, mildew is a common phenomenon, and it is known that differences in the environment, lighting, temperature, humidity, substrate pH, and other factors in addition to the coating composition affect the susceptibility of a given painted surface.
Industries that we serve. It is the responsibility of the user of this standard f5590 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Historical Version s – view previous versions of standard. Bioassays pH Simulation studies. All pre-conditioning must be detailed in the final report.
This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions. Paint designated for service in exterior conditions should be pre-conditioned by laboratory accelerated weathering prior to exposure to fungi.

Shubhda Research Institute offers hands-on practical training ashm at different levels addressing specific industries so as to hone your skills and techniques. Antimicrobial Textiles For Fungi. Antimicrobial Textiles For Bacteria. Work Item s – proposed revisions of this standard. Negative, positive and reference controls are run in parallel. Either or both the tests can be run in parallel depending on sponsor requirement.
The test can be performed for severe challenge by use of nutritive medium and lesser challenge by using a mineral salt agar. s5590
This method is used for accelerated study for determining the relative resistance of two or more paints or coating films to fungal growth. This test method should not be used by persons without at least basic microbiological training. The values given in parentheses are for information only.
ASTM D5590 – Fungal Defacement Test
This test method however, should not be used as a replacement for exterior exposure that is, Practice D since many other factors, only a few of which are listed will affect those results. Rapid testing and quick reliable results are of utmost importance today.
It is hoped that a ranking of relative performance would be similar to that ranked from outdoor exposures. Shubhda Research Institute Unit No.
Link to Active This link will always route to the current Active version of the standard. Incubation is done at controlled high humidity. Antimicrobial Hard Surfaces For Bacteria. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is generally known that differences in the environment, lighting, temperature, humidity, substrate pH, and other factors in addition to the coating composition affect the susceptibility of a given painted surface.
This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions.
Six test pieces are required per test sample for individual and pooled fungal inoculum. Antimicrobial Hard Surfaces For Fungi. The method is not intended to simulate or replace indoor wstm outdoor exposure of paint films or related coatings.
It does not imply that a coating that resists growth under these conditions will necessarily resist growth in the actual application.
