ASTM Pre-Saturated Towelettes Test

Test Purpose
The purpose of this microbiology lab test is to determine the efficacy of a client's pre-saturated towelette product as a hard surface disinfectant to comply with the U.S. Environmental Protection Agency and other regulatory agency requirements. The test procedure is to simulate the way in which the product is intended to be used.

Test Summary
A film of bacterial cells is dried on a surface of glass carriers and is then wiped with the towelette and exposed to the test substance for a specified contact time. After exposure, the glass carriers are transferred to vessels containing neutralizing subculture media and assayed qualitatively for survivors. Appropriate viability, dried organism population, and neutralization confirmation controls are performed.
