This method is used for accelerated study for determining the relative resistance of two or more paints or coating films to fungal growth. Negative, positive and reference controls are run in parallel.
Antimicrobial Textiles For Bacteria. This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions. Work Item s – proposed revisions of this standard. Six test pieces are required per test sample for individual and pooled fungal inoculum. Referenced Asrm purchase separately The dd5590 listed below are referenced within the subject standard but are not provided as part of the standard.
Industries that we serve.
This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions. Antimicrobial Textiles For Fungi. The method is not intended to simulate or replace indoor or outdoor exposure astk paint films or related coatings. Rapid testing and quick reliable results are of utmost importance today.
Shubhda Research Institute offers hands-on practical training programs at different levels addressing specific industries so as to hone your skills and techniques. Link d55590 Active This link will always route to the current Active version of the standard.
ASTM D5590 – Fungal Defacement Test
The test can be performed for severe challenge by use of nutritive medium and lesser challenge by using a mineral salt agar. Paint designated for service in exterior conditions should be pre-conditioned by laboratory accelerated weathering prior to exposure to fungi. Either or both the tests can be run in parallel depending on sponsor requirement.
All pre-conditioning must be detailed in the final report. Incubation is done at controlled high humidity. Shubhda Research Institute Unit No. 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.
Disinfectants And Sanitizers Testing. It does not imply that a coating that resists growth under these conditions will necessarily resist growth in the actual application. 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.
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.
Antimicrobial Hard Surfaces For Fungi. It is hoped that a ranking of relative performance would be similar to that ranked from outdoor exposures. Historical Version s – view previous versions of standard.
