EN 17658:2022

This document specifies a test method and the minimum performance requirements for the microbicidal efficacy of a chemical product intended for use in a wash process in a domestic environment, in a domestic wash equipment at low temperatures (≤40 °C). This procedure does not apply to certain types of laundry disinfection technologies which require specific devices (i.e. active substances generated in situ using specific devices). This method is not limited to certain types of textiles, types of products or steps in the washing cycle.According to a phase 2, step 2 test definition, this document establishes the efficacy in laboratory test simulating practical use conditions of a chemical product.This document cannot be applied when the disinfection is medical indicated (medical area) or in hygiene-sensitive areas where professional reprocessing of laundry is required (i.e. food, healthcare, medical and cleanroom sectors, PPE, and workwear). In those cases, EN 16616 and EN 14065 will apply.NOTEThis method corresponds to a phase 2, step 2 test (see EN 14885).EN 14885 specifies in detail the relationship of the various tests to one another and to “use recommendations”.
