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.

Industries that we serve. It is the responsibility of the user of this standard f5590 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Historical Version s – view previous versions of standard. Bioassays pH Simulation studies. 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. Paint designated for service in exterior conditions should be pre-conditioned by laboratory accelerated weathering prior to exposure to fungi.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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 test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions.

Six test pieces are required per test sample for individual and pooled fungal inoculum. Antimicrobial Hard Surfaces For Fungi. The method is not intended to simulate or replace indoor wstm outdoor exposure of paint films or related coatings.

It does not imply that a coating that resists growth under these conditions will necessarily resist growth in the actual application.
