EPA Residual Self-Sanitizing
Activity Test
Test Purpose
The purpose of this microbiology
lab test is to quantitatively
determine the residual
sanitizing efficacy of a
client's antimicrobial product
after application to inanimate,
nonporous, non-food contact hard
surfaces followed by multiple
wear and reinoculations cycles.
This method is designed to
comply with the U.S.
Environmental Protection
Agency’s requirements.
Test Summary
This method applies to products
intended for use on inanimate,
nonporous, non-food contact hard
surfaces for the evaluation of
residual antimicrobial efficacy.
These products may be sprayed or
applied by other means as
specified. This protocol
describes the microorganisms,
equipment, data collection and
procedures for evaluating a
residual sanitizer for non-food
contact surfaces. This method
includes a regimen by which each
treated surface undergoes
specific wear exposures and
reinoculation procedures to
demonstrate residual efficacy of
the test product. Appropriate
sterility, population, purity,
and neutralization controls are
performed.
