Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 4126-7 was prepared by the European Committee for Standardization (CEN) in collaboration with
Technical Committee ISO/TC 185, Safety devices for protection against excessive pressure, in accordance
with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
Throughout the text of this document, read “.this European Standard.” to mean “.this International
Standard.”.
ISO 4126 consists of the following parts, under the general title Safety devices for protection against
excessive pressure:
— Part 1: Safety valves
— Part 2: Bursting disc safety devices
— Part 3: Safety valves and bursting disc safety devices in combination
— Part 4: Pilot-operated safety valves
— Part 5: Controlled safety pressure relief systems (CSPRS)
— Part 6: Application, selection and installation of bursting disc safety devices
— Part 7: Common data

Foreword
This document (EN ISO 4126-7:2004) has been prepared by Technical Committee CEN/TC 69 “Industrial valves”,
the secretariat of which is held by AFNOR, in collaboration with Technical Committee ISO/TC 185 “Safety devices
for protection against excessive pressure”.
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 August 2004 , and conflicting national standards shall be withdrawn at the latest
by August 2004 .
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
This document includes a bibliography.
Annexes A and B are informative.
This European Standard for safety devices for protection against excessive pressure consists of seven parts of
which this is part 7. The various parts are:
Part 1 : Safety valves
Part 2 : Bursting disc safety devices
Part 3 : Safety valves and bursting disc safety devices in combination
Part 4 : Pilot operated safety valves
Part 5 : Controlled Safety Pressure Relief Systems (CSPRS)
Part 6 : Application, selection and installation of bursting disc safety devices
Part 7 : Common data
This Part 7 contains data, which is common to more than one of the parts of this standard to avoid unnecessary
repetition. This part is referenced in the other parts of this standard where appropriate.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de
droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable de ne
pas avoir identifié de tels droits de propriété et averti de leur existence.
L'ISO 4126-7 a été élaborée par le Comité européen de normalisation (CEN) en collaboration avec le comité
technique ISO/TC 185, Dispositifs de sûreté pour la protection contre les excès de pression, conformément à
l'Accord de coopération technique entre l'ISO et le CEN (Accord de Vienne).
Tout au long du texte du présent document, lire «… la présente Norme européenne …» avec le sens de
«… la présente Norme internationale …».
L'ISO 4126 comprend les parties suivantes, présentées sous le titre général Dispositifs de sécurité pour
protection contre les pressions excessives:
— Partie 1: Soupapes de sûreté
— Partie 2: Dispositifs de sûreté à disque de rupture
— Partie 3: Soupapes de sûreté et dispositifs à disque de rupture combinés
— Partie 4: Soupapes de sûreté pilotées
— Partie 5: Dispositifs de sûreté à décharge contrôlés contre les surpressions (DSDCS)
— Partie 6: Application, sélection et installation des dispositifs de sûreté à disque de rupture
— Partie 7: Données communes

Avant-propos
Le présent document EN ISO 4126-7:2004 a été élaboré par le Comité Technique CEN/TC 69 “Robinetterie
industrielle”, dont le secrétariat est tenu par AFNOR, en collaboration avec le Comité Technique ISO/TC 185
“Dispositifs de sûreté pour la protection contre les surpressions”.
Cette Norme européenne devra recevoir le statut de norme nationale, soit par publication d'un texte identique, soit
par entérinement, au plus tard en août 2004, et toutes les normes nationales en contradiction devront être retirées
au plus tard en août 2004.
Selon le Règlement Intérieur du CEN/CENELEC, les instituts de normalisation nationaux des pays suivants sont
tenus de mettre cette Norme européenne en application : Allemagne, Autriche, Belgique, Danemark, Espagne,
Finlande, France, Grèce, Irlande, Islande, Italie, Luxembourg, Malte, Norvège, Pays-Bas, Portugal, République
Tchèque, Royaume-Uni, Suède et Suisse.
La présente Norme européenne relative aux dispositifs de sécurité pour la protection contre les pressions
excessives comprend sept parties dont celle-ci est la partie 7. Les diverses parties sont :
¾ Partie 1 : Soupapes de sûreté
¾ Partie 2 : Dispositifs de sûreté à disque de rupture
¾ Partie 3 : Dispositifs de sûreté associant soupapes de sûreté et disques de rupture
¾ Partie 4 : Soupapes de sûreté pilotées
¾ Partie 5 : Dispositifs de sécurité à décharge contrôlés contre les surpressions (DSDCS)
¾ Partie 6 : Application, sélection et installation des dispositifs de sûreté à disque de rupture
¾ Partie 7 : Données communes.
La partie 7 contient des données qui sont communes à plus d’une des parties de la présente norme pour éviter les
répétitions inutiles. Cette partie est référencée dans les autres parties de la présente norme de façon appropriée.
Les Annexes A et B sont informatives.
Ce document comprend une bibliographie.
