What is ISO 22610?

ISO 22610:2018 specifies a test method, with associated test apparatus, which is used to determine the resistance of a material to the penetration of bacteria, carried by a liquid, when subjected to mechanical rubbing.

Summary of tests

Resistance to wet bacterial penetration, ISO 22610

• This test uses an electrically driven turntable to rotate an agar plate while a vertical finger presses on a material inoculated with bacteria.  The inoculated material, called the donor, lies on top of the test article.  The finger is moved over the entire surface of the plate at a rate of 60 revolutions per minute for 15 minutes.  The finger exerts a 3 Newton force on the agar plate.  Due to the effect of rubbing and liquid migration, bacteria can pass from the donor through the test specimen down to the agar plate.  The results characterize the barrier capability and the penetration over time.
