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 c5590 weathering prior to exposure to fungi. Link to Active This link will always route to the current Active version of the standard. Negative, positive and reference controls are run in parallel.

It is hoped that a ranking of relative performance would be similar to that ranked from outdoor exposures. 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.

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.

Antimicrobial Hard Surfaces For Fungi. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

This test method should not be used by persons without at least basic microbiological training. Either or both the tests can be run in parallel depending on sponsor requirement. 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. The method is not intended to simulate or replace indoor or outdoor exposure of paint films or related coatings.

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.
