This document specifies safety requirements for the construction and performance of safe breaks to be fitted to metering pumps and dispensers installed at filling stations and used to dispense liquid fuels and aqueous urea solution into the tanks of motor vehicles, boats and light aircraft and into portable containers at flow rates up to 200 l \u00b7 min\u22121. This document applies to fuels of subdivision Group IIA according to EN ISO\/IEC 80079-20-1 and also aqueous urea solution according to ISO 22241-1. The requirements apply to safe breaks at ambient temperatures from \u221220 \u00b0C to +40 \u00b0C with the possibility for an extended temperature range. This document pays particular attention to electrical, mechanical and hydraulic characteristics of, and electrical equipment incorporated within or mounted on, the safe break. This document applies mainly to hazards related to the ignition of liquid fuels being dispensed or their vapour. This document also addresses electrical and mechanical hazards. This document does not apply to equipment dispensing compressed or liquefied gases.<\/p>\n
