Either or both the tests can be run in parallel depending on sponsor requirement. Paint designated for service in exterior conditions should be pre-conditioned by laboratory accelerated weathering prior to exposure to fungi.
The test can be performed for severe challenge by use of nutritive medium and lesser challenge by using a mineral salt agar. Work Item s – proposed revisions of this standard. It is hoped that a ranking of relative performance would be similar to that ranked from outdoor exposures.
The values d55590 in parentheses are for information only. Antimicrobial Hard Surfaces For Bacteria. Six test pieces are required per test sample for individual and pooled fungal inoculum.
ASTM D5590 – Fungal Defacement Test
Incubation is done at controlled high humidity. 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. Bioassays pH Simulation studies. Negative, positive and reference controls are run in parallel. 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.
The method is not intended to simulate or r5590 indoor or outdoor exposure of paint films or related coatings. Shubhda Research C5590 Complete solutions for all your Microbiology testing needs!
This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions. Historical Version s – view previous versions of asm.

Shubhda Research Institute Unit No. This method is used for accelerated study for determining the relative resistance of two or more paints asgm coating films to fungal growth. Disinfectants And Sanitizers Testing. Link to Active This link will always route to the current Active version of the standard. Rapid testing and quick reliable results are of utmost importance today.
This test method attempts sstm provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions. 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 offers hands-on practical training programs at different levels xstm specific industries so as to hone your skills and techniques. All pre-conditioning must be detailed in the final report.
This test asrm 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.
