Disinfectant / Antimicrobial Contact (Dwell) Time Reference
Returns the label-typical wet contact (dwell) time for common EPA-registered antimicrobial classes (quat, accelerated hydrogen peroxide, bleach solution, phenolic, botanical/thymol) and the keep-wet and pre-clean rules that decide whether a disinfection claim is actually achieved. Antimicrobials are EPA-registered pesticides whose label is the legal authority (FIFRA); the ranges are guidance and S500/S520 govern.
Formula and source
Reference lookup: product class -> label-typical wet contact (dwell) time range, keep-wet rule, pre-clean rule, and the FIFRA label authority. No numeric computation beyond the lookup.
Antimicrobial contact-time principle, by name; ANSI/IICRC S500 and S520. Antimicrobials are EPA-registered pesticides whose label is the legal authority under FIFRA.
