DIN EN 17818:2024-04

This document defines the minimum requirements for treatment systems, which generate the active substance - "Active chlorine" - from sodium chloride by electrolysis for on-site (in situ) operation. The in situ generated active substance (IGAS), in this case active chlorine, may be put into a solution ("off-line") or directly generated in the pipes ("in-line"). This document specifies the device construction, and test methods for the equipment used for in situ generation of active chlorine. It specifies requirements for instructions for installation, operation, maintenance, safety and for documentation to be provided with the product. This document (EN 17818:2023) has been prepared by Technical Committee CEN/TC 164 "Drinking water treatment", the secretariat of which is held by AFNOR (France). The responsible national standardization committee is DIN-DVGW Joint Working Group NA 119-07-13-01 AK "EN für Anlagen zur In-Situ-Erzeugung und Dosierung von Bioziden zur Wasserbehandlung" ("EN for devices for in-situ generation and dosage of biocides for water treatment") at DIN Standards Committee Water Practice (NAW).
