This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions.
It is generally astk 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.
Antimicrobial Textiles For Fungi. Shubhda Research Institute Complete solutions for all your Microbiology testing needs!
It is hoped that a ranking of relative performance would be similar to that ranked from outdoor exposures. Disinfectants And Sanitizers Testing.
Industries that we serve. The method is not intended to simulate or replace indoor or outdoor exposure of paint films or related coatings. Antimicrobial Textiles For Bacteria.
ASTM D5590 – Fungal Defacement Test
This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions. It does not imply that a coating that resists growth under these conditions will necessarily resist growth in the actual application. Paint designated for service in exterior conditions should be pre-conditioned by laboratory accelerated weathering prior to exposure to fungi. Incubation is done at controlled high humidity.
Shubhda Research Institute offers hands-on practical training programs at different levels addressing specific industries so as to hone your skills and techniques. Shubhda Research Institute Unit No. Either or both the tests can be run in parallel depending on sponsor requirement.
ASTM D – Fungal Defacement Test | Situ Biosciences LLC
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. Rapid testing and quick reliable results are of utmost importance today.
Six test pieces are required per test sample for individual and pooled fungal inoculum. The test can be performed for severe challenge by use of nutritive medium and lesser challenge by using a mineral salt satm. Antimicrobial Hard Surfaces For Bacteria. This test method however, should not be used as a replacement for exterior exposure that is, Practice D d55590 many d559 factors, only a few of which are listed will affect those results.
Link to Active This link will always route to the current Active version of the standard. Bioassays pH Simulation studies. This method is used for accelerated study for determining the relative resistance of two or more paints or coating films to fungal growth.
Historical Version s – view previous versions of standard. It d550 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.
This test method should not be used by persons without at least basic microbiological training. All pre-conditioning must be detailed in the final report. The values given asmt parentheses are for information only.
