Pressure regulators and associated safety devices for gas appliances - Part 1: Pressure regulators for inlet pressures up to and including 500 mbar

This European Standard specifies the safety, construction and performance requirements for pressure regulators, (hereafter referred to as regulators), intended for use with gas burners and gas burning appliances using fuel gases of the 1st, 2nd and 3rd families. This European Standard covers type testing only. It also gives information necessary for the purchaser and user.
This European Standard is applicable to regulators, which may be tested independently of these appliances, having a connection size up to and including DN 250 and a declared maximum working pressure up to and including 500 mbar.
The methods of test given in this European Standard are intended for product type testing only. Tests intended for production testing are not specifically included.
Regulators intended to be used on installations for the 3rd family gases are also covered by EN 13785 and EN 13786.
This European Standard does not cover:
a)   pressure regulators connected directly to mains pipework or to a container that maintains a standard distribution pressure;
b)   pressure regulators intended for gas appliances to be installed out-of-doors and exposed to the environment;
c)   pressure regulators which use electrical auxiliary energy.

Diese Europäische Norm legt die Sicherheits , Konstruktions  und Leistungsanforderungen an Druckregler (nachstehend Regler genannt) fest, die für die Verwendung mit Gasbrennern und Gasgeräten mit einer Auslegung für Brenngase der ersten, zweiten oder dritten Gasfamilie vorgesehen sind. Diese Europäische Norm bezieht sich nur auf die Baumusterprüfung. Sie enthält auch Informationen, die für Käufer und Anwender erforderlich sind.
Diese Europäische Norm gilt für Regler für Gasbrenner und Gasverbrauchseinrichtungen mit Anschluss¬nennweiten bis einschließlich DN 250 und einen angegebenen höchsten Betriebsdruck bis einschließlich 500 mbar, die unabhängig von den Gasverbrauchseinrichtungen geprüft werden können.
Die in dieser Europäischen Norm angegebenen Prüfverfahren sind lediglich für die Baumusterprüfung des jeweiligen Produkts vorgesehen. Spezielle Verfahren für die Produktionsprüfung werden nicht erfasst.
Regler, die für eine Anwendung an Einrichtungen für die 3. Gasfamilie bestimmt sind, werden auch in EN 13785 und EN 13786 behandelt.
Diese Europäische Norm gilt nicht für:
a)   Regler, die unmittelbar an eine Versorgungsleitung oder an einen Behälter mit genormtem Verteilungsdruck angeschlossen sind;
b)   Regler für Gasgeräte in Freiluftausführung, die Umwelteinflüssen ausgesetzt sind;
c)   Regler, die elektrische Hilfsenergie benötigen.

Régulateurs de pression et dispositifs de sécurité associés pour appareils à gaz - Partie 1: Régulateurs de pression pour pression amont inférieure ou égale à 500 mbar

La présente norme spécifie les exigences de sécurité, de construction et de fonctionnement des régulateurs de pression, (désignés ci-après régulateurs), destinés à être utilisés avec des brûleurs à gaz et des appareils à gaz alimentés par des combustibles gazeux des 1re, 2e et 3e familles. La présente Norme européenne couvre uniquement les essais de type. Elle fournit également des informations nécessaires pour l’acheteur et l’utilisateur.
La présente Norme européenne s’applique aux régulateurs, qui peuvent être essayés indépendamment de ces appareils, d’un diamètre nominal de raccordement jusqu’à DN 250 inclus, ayant une pression maximale de service déclarée inférieure ou égale à 500 mbar.
Les méthodes d’essai données dans la présente norme sont destinées uniquement à l’essai de type du produit. Les essais destinés à en contrôler la production n’y sont pas particulièrement compris.
Les régulateurs destinés à être utilisés dans des installations utilisant les gaz de 3e famille sont également couverts par l’EN 13785 et l’EN 13786.
La présente norme ne traite pas :
a)   des régulateurs raccordés directement au réseau de distribution ou à un récipient qui maintient en aval une pression de distribution normalisée ;
b)   des régulateurs destinés à des appareils à gaz devant être installés à l’extérieur et exposés aux intempéries ;
des régulateurs alimentés par une source d’énergie électrique auxiliaire.

Foreword
This document (EN 88-1:2007) has been prepared by Technical Committee CEN/TC 58 “Safety and
control devices for gas burners and gas burning appliances”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2008, and conflicting national standards shall be
withdrawn at the latest by May 2008.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
This document supersedes EN 88:1991.
EN 88 consists of the following parts:
Part 1: Pressure regulators for inlet pressures up to and including 500 mbar;
Part 2: Pressure regulators for inlet pressures above 500 mbar up to and including 5 bar.
This European Standard was revised to make reference to EN 13611 and to increase the pressure
range to 500 mbar and connection up to and including DN 250, but not because of any “shortcoming”.
This European Standard is intended to be used in conjunction with EN 13611.
SIL classification according to EN 61508 cannot automatically be claimed based upon compliance
with this European Standard. Valves with SIL classification do not automatically meet the
requirements of this European Standard.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
Introduction
This European Standard is a particular standard for pressure regulators for gas burners and gas-
burning appliances which cites EN 13611 wherever possible. This European Standard supplements or
modifies the corresponding clauses of EN 1 3611. The construction and performance requirements
are as far as applicable in total conformity with EN 13611.
