The proposed scope of this guide is to quantitatively assess the percent surface area coverage of wet disinfectants at a given dwell time. The working group will determine how to write the standard to include as many chemistries, materials and application methods (e.g., wipe, spray, electrostatic spray) as possible.
Disinfectant:Dwell Time:Contact Time:Surface Coverage:Surface Area Coverage:Sanitize:Antimicrobial
This standard is needed because lab methods used to qualify disinfectants and make claims do not reflect real world use conditions. This represents a critical gap in the field that will be addressed in this work. This protocol will provide instructions to assess disinfectant spreading and de-wetting at given contact times that people can use in the setting where the disinfectant will be used and using the desired application method by adding a dye to the disinfectant solution and providing quantitative analysis instructions.
The title and scope are in draft form and are under development within this ASTM Committee.
