Rubber and plastic hoses and hose assemblies with internal vapour recovery for measured fuel dispensing systems - Specification

This document specifies the requirements and test methods for verification 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 need to be capable of withstanding anticipated mechanical, thermal and chemical stressing and be resistant to the combustible liquids used in these applications as well as their vapour and vapour air mixtures. It is imperative that the assemblies be constructed in such a way that actions during normal operation cannot give rise to dangerous electrostatic charges nor that there will 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 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.
NOTE   This document is not applicable to multi chamber fuel dispensing hoses.
As part of the certification of a new dispenser, testing of fuel samples in accordance with EN 228 are carried out at least eight weeks after the first use of the equipment to avoid unrepresentative sulphur content results.

Tuyaux et assemblages flexibles à récupération interne de vapeur pour systèmes de livraison mesurée de carburant - Spécification

Le présent document spécifie les exigences et les méthodes d’essai pour la vérification des assemblages flexibles à récupération de vapeur des systèmes de distribution équipant les stations-service.
Il est nécessaire que les assemblages flexibles à récupération de vapeur pour les systèmes de distribution équipant les stations-service supportent les contraintes mécaniques, thermiques et chimiques prévues et soient résistant aux combustibles liquides utilisés dans ces applications ainsi qu'à leur vapeur et aux mélanges air-vapeur. Il est impératif que les assemblages soient construits de manière à ce que des actions effectuées en fonctionnement normal ne puissent pas provoquer des charges électrostatiques dangereuses, ni réduire les performances de récupération de vapeur.
Les assemblages sont destinés à être utilisés à des températures ambiantes comprises entre –30 °C et +55 °C pour une classe de températures normales et entre –40 °C et +55 °C pour une classe de basses températures à une pression de service  16 bar .
Les tuyaux peuvent être fabriqués à partir de caoutchouc ou d'élastomères thermoplastiques (TPE) et le présent document spécifie les exigences pour trois types de tuyaux avec deux catégories et deux classes d’assemblages flexibles pour les systèmes de livraison mesurée de carburant, y compris les carburants oxygénés (≤ 15 % mélanges oxygénés) avec tube ou tuyau interne de récupération de vapeur.
NOTE   Le présent document ne s’applique pas aux tuyaux multi-chambres pour distribution de carburants.
Dans le cadre de la certification d’un nouveau distributeur, des essai d’échantillons de carburant selon l’EN 228 sont à réaliser au moins huit semaines après la première utilisation de l'équipement afin d'éviter des résultats en teneur en soufre peu représentatifs.

European foreword

This document (prEN 13483:2021) has been prepared by Technical Committee CEN/TC 218 “Rubber

and plastics hoses and hose assemblies”, the secretariat of which is held by BSI.

This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13483:2013.
In comparison with EN 13483:2013, the following changes have been made:
a) the normative references have been updated;
b) in 7.3 the concentricity tolerance has been narrowed from 1,0 mm to 0,7 mm;

c) in Table 4 the “Low temperature class” has been increased from 18 ml to 22 ml;

d) Clause 9 “End fittings” has been amended so that mechanically suitable, conductive plastics may be

used as an alternative to metallic materials;

e) the document has been aligned with the 2017 issue of the guidance document prepared by

ISO/TC 45/SC 1 on the layout of ISO and CEN standards on rubber and plastics hoses and hose

assemblies (most notably with respect to Clause 11 “Frequency of testing”, Clause 12 “Marking”,

and the pressure units used);
f) Informative Annex E concerning environmental aspects has been added.

WARNING — Persons using this document are assumed to be familiar with normal laboratory

practice. This document does not purport to address all of the safety problems, if any, associated

with its use. It is the responsibility of the user to establish appropriate safety and health

practices and to ensure compliance with any national regulatory conditions.

1 Scope

This document specifies the requirements and test methods for verification 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 need to be

capable of withstanding anticipated mechanical, thermal and chemical stressing and be resistant to the

combustible liquids used in these applications as well as their vapour and vapour air mixtures. It is

imperative that the assemblies be constructed in such a way that actions during normal operation

cannot give rise to dangerous electrostatic charges nor that there will 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 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.
NOTE This document is not applicable to multi chamber fuel dispensing hoses.

As part of the certification of a new dispenser, testing of fuel samples in accordance with EN 228 are

carried out at least eight weeks after the first use of the equipment to avoid unrepresentative sulphur

content results.
