scope:

This document specifies the requirements and test methods for verification for hose assemblies with vapour recovery for delivery systems on petrol filling stations.

Hoses can be constructed from rubber or thermoplastic elastomer (TPE) and this document specifies the requirements for three types of hoses in two grades and two classes of hose assemblies for measured fuel dispensing systems, including oxygenated fuels (≤15 % oxygenated compounds) with internal vapour recovery tubing or hose made out of rubber or thermoplastic elastomer (TPE).

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 ¹.

This document is not applicable to multi chamber fuel dispensing hoses.

NOTE As part of the certification of a new dispenser, testing of fuel samples in accordance with EN 228 is carried out at least eight weeks after the first use of the equipment to avoid unrepresentative sulphur content results.

¹ 1 bar = 0,1 MPa.
