This method is used for accelerated study for determining the relative resistance of two or more paints or coating films to fungal growth.
Bioassays pH Simulation studies. Negative, positive and reference controls are run in parallel. This test method should not be used by persons without at least basic microbiological training.
The test can be performed for severe challenge by use of nutritive medium and lesser challenge by using a mineral salt asttm. Disinfectants And Sanitizers Testing.

ASTM D5590 – Fungal Defacement Test
It does not imply that a coating that resists growth under these conditions will necessarily resist growth in the actual application. Shubhda Research Institute Unit No. Industries that we serve. Antimicrobial Textiles For Fungi.

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. Shubhda Research Institute Complete solutions for all your Microbiology aatm needs! Work Item s – proposed revisions of this standard. Antimicrobial Hard Surfaces For Fungi.
Link to Active This v5590 will always route to the current Active version of the standard. 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.
Antimicrobial Hard Surfaces For Bacteria. The method is not intended to simulate or atsm indoor or outdoor exposure of paint films or related coatings. Six test pieces are required per test sample for individual and pooled fungal inoculum. Paint designated for service in exterior conditions should be pre-conditioned by laboratory accelerated weathering prior to exposure to fungi.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Incubation is done at controlled high humidity. The values given in parentheses are for information only. Antimicrobial Textiles For Bacteria. 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.
It is hoped that a ranking of relative performance would be similar to that ranked from outdoor exposures. 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. This test method attempts to provide a means to comparatively evaluate different coating formulations for e5590 relative performance under a given set of conditions.
Either or both the tests awtm be run in parallel depending on sponsor requirement. Rapid testing and quick reliable results are of utmost importance today.
