This document specifies safety and environmental requirements for the construction and performance of shear valves to be fitted to metering pumps, dispensers, and/or satellite delivery systems installed at petrol 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 · min?1.

This document applies to fuels and their vapours 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 shear valves at ambient temperatures from ?20 °C to +40 °C with the possibility for an extended temperature range.

This document pays particular attention to mechanical and hydraulic characteristics.

This document does not apply to equipment dispensing compressed or liquefied gases.
