This document specifies the requirements for hose assemblies with vapour recovery for delivery systems on petrol filling stations.
The hose assemblies with vapour recovery for delivery systems on petrol filling stations shall be capable of withstanding anticipated mechanical, thermal and chemical stressing and shall be resistant to the combustible liquids used in these applications as well as their vapour and vapour air mixtures. The assemblies shall be constructed in such a way that actions during normal operation cannot give rise to dangerous electrostatic charges nor shall there be any reduction in the performance of the vapour recovery.
The assemblies are intended for use at ambient temperatures between –30 °C and +55 °C for normal temperature class and –40 °C and +55 °C for low temperature class at a working pressure =16 bar. Hoses may be constructed from rubber or thermoplastic elastomer (TPE) and this document specifies the requirements for three types of hoses in two categories and two classes of hose assemblies for measured fuel dispensing systems, including oxygenated fuels (= 15 % oxygenated compounds) with internal vapour recovery tubing or hose.
NOTE This document does not apply to multi chamber fuel dispensing hoses.
