Shubhda Research Institute offers hands-on practical training programs at different levels addressing specific industries so as to hone your skills and techniques. Link to Active This link 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 asm.
Shubhda Research Institute Unit No. 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 method is used for accelerated study for determining the relative resistance of two or more paints or coating films to fungal growth. All pre-conditioning must be detailed in the final report. It is hoped that a ranking of relative d559 would be similar to that ranked from outdoor exposures. Antimicrobial Textiles Aztm Fungi. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the ast.

It is the responsibility of the user of this v5590 to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Antimicrobial Hard Surfaces For Bacteria. 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. 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 should not be used by persons without at least basic microbiological training. Antimicrobial Hard Surfaces For Fungi.
Bioassays pH Simulation studies. Work Item s – proposed revisions of this standard. Either or both the tests can be run in parallel depending on sponsor requirement.
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. Historical Version s – view previous versions of standard. The method is not intended to simulate or replace indoor or outdoor exposure of paint films or related coatings. The test can be performed for severe challenge by use of nutritive medium and aatm challenge by using a mineral salt agar. This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions.
Negative, positive and reference controls are run in parallel.
