Exposure time

The time the disinfectant must be in contact with the targeted organism to inactivate or kill it under the conditions stated on the manufacturers label instructions. For example, if the kill time for a spore is 10 minutes, the use dilution of a liquid disinfectant must remain wet and in contact for the entire 10 minutes, and not be wiped off or dry of its own accord until the 10 minute kill time is completed.
