Safety and control devices for oil burners and oil-burning appliances - Particular requirements - Part 1: Automatic and semi-automatic valves (ISO 23553-1:2022)
This document specifies safety, constructional and performance requirements and testing of automatic
and semi-automatic valves for oil.
It applies to automatic and semi-automatic valves which are:
— normally closed;
— used in combustion plants to interrupt the oil flow with or without delay on closing;
— for use with oil types (e.g. middle distillate fuel oil, crude oil, heavy fuel oil or kerosene) without
gasoline;
NOTE 1 For other oil types (e.g. oil emulsions), additional test methods can be agreed between the
manufacturer and the test authority.
NOTE 2 Oil types from petroleum refining processes are classified ISO-F-D in ISO 8216-99 and form part
of a device having other function(s), such as oil pumps. In this case, the test methods apply to those parts
or components of the device forming the automatic and semi-automatic valves, i.e. those parts which are
necessary for the closing function.
— for use on burners or in appliances using oil;
— directly or indirectly operated, electrically or by mechanical or hydraulic means;
— fitted with or without closed-position indicator switches.
This document covers type testing only
Sicherheits-, Regel- und Steuereinrichtungen für Ölbrenner und Öl verbrennende Geräte - Spezielle Anforderungen - Teil 1: Automatische und halbautomatische Ventile (ISO 23553-1:2022)
Dieses Dokument legt die Anforderungen an Sicherheit, Konstruktion und Leistung sowie die Prüfung von automatischen und halbautomatischen Ventilen für Öl fest.
Es ist anzuwenden für automatische und halbautomatische Ventile, die:
— normal schließen;
— in Verbrennungsanlagen eingesetzt werden, um den Öldurchfluss mit oder ohne Verzögerung des Schließvorgangs zu unterbrechen;
— für den Einsatz mit Ölsorten ohne Benzin (z. B. Diesel, Rohöl, Schweröl oder Kerosin) vorgesehen sind;
ANMERKUNG 1 Für weitere Ölsorten (z. B. Ölemulsionen) können zwischen Hersteller und Prüfstelle zusätzliche Prüfverfahren vereinbart werden.
ANMERKUNG 2 Ölsorten aus Raffinerieprozessen sind in ISO 8216 99 als ISO F D klassifiziert und bilden einen Teil einer Einrichtung mit (einer) anderen Funktion(en), z. B. Ölpumpen. In diesem Fall gelten die Prüfverfahren für diejenigen Bauteile oder Komponenten der Einrichtung, die die automatischen und halbautomatischen Ventile bilden, d. h. die Bauteile, die für die Schließfunktion erforderlich sind.
— für die Anwendung an Brennern oder in Geräten vorgesehen sind, die Öl nutzen;
— direkt oder indirekt elektrisch oder durch mechanische oder hydraulische Hilfsmittel betrieben werden;
— mit Anzeigen für die Geschlossenstellung ausgestattet sind oder nicht.
Dieses Dokument deckt nur Typprüfungen ab.
Dispositifs de commande et de sécurité pour brûleurs à combustible liquide et pour appareils à combustible liquide - Exigences particulières - Partie 1: Robinets automatiques et semi-automatiques (ISO 23553-1:2022)
Le présent document spécifie les exigences relatives à la sécurité, à la conception et aux performances ainsi que les essais applicables aux robinets automatiques et semi-automatiques destinés à des appareils à combustible liquide.
Il s'applique aux robinets automatiques et semi-automatiques qui sont:
— normalement fermés;
— utilisés dans des installations de combustion dans le but d'interrompre l'écoulement du combustible liquide avec ou sans retard sur la fermeture;
— conçus pour être utilisés avec des types de combustibles liquides (par exemple, fioul de distillat moyen, pétrole brut, fioul lourd ou kérosène) sans essence;
NOTE 1 Pour les autres types de combustibles liquides (par exemple, émulsions de combustible), le constructeur et l'autorité effectuant les essais peuvent convenir de méthodes d'essai supplémentaires.
NOTE 2 Les types de combustibles liquides issus de processus de raffinage du pétrole sont classés en catégorie ISO-F-D dans l'ISO 8216-99 et font partie d'un dispositif ayant d'autres fonctions, par exemple des pompes à combustible liquide. Dans ce cas, les méthodes d'essai s'appliquent aux parties ou aux composants du dispositif qui constituent les robinets automatiques et semi-automatiques, c'est-à-dire les parties qui sont nécessaires à la fonction de fermeture.
— conçus pour être utilisés sur des brûleurs ou des appareils à combustible liquide;
— actionnés directement ou indirectement par un moyen électrique, mécanique ou hydraulique;
— équipés ou non de commutateurs à indicateurs de position fermée.
Le présent document couvre uniquement les essais de type.
Varnostne in nadzorne naprave za oljne gorilnike in aparate na olje - Posebne zahteve - 1. del: Avtomatski in polavtomatski ventili (ISO 23553-1:2022)
Ta dokument določa varnostne zahteve, konstrukcijske zahteve in zahteve glede zmogljivosti ter metode za preskušanje avtomatskih in polavtomatskih ventilov za olje.
Uporablja se za avtomatske in polavtomatske ventile, ki:
– so običajno zaprti;
– se uporabljajo v kurilnih napravah za prekinitev dotoka olja z zakasnjenim zapiranjem ali brez njega;
– se uporabljajo z vrstami olja brez bencina (npr. srednje destilatno kurilno olje, surova nafta, težko kurilno olje ali kerozin);
OPOMBA 1: Pri drugih vrstah olja (npr. oljne emulzije) se lahko proizvajalec in organ za preskušanje dogovorita o dodatnih preskusnih metodah.
OPOMBA 2: Vrste olja, pridobljene z rafinacijo nafte, so uvrščene v kategorijo ISO-F-D v standardu ISO 8216-99 in so del
naprave, ki opravlja druge funkcije (npr. črpalka za olje). V tem primeru se preskusne metode uporabljajo za dele ali komponente naprave, ki tvorijo avtomatske in polavtomatske ventile, tj. tiste dele, ki so potrebni za funkcijo zapiranja.
– se uporabljajo v gorilnikih ali aparatih na olje;
– se upravljajo posredno ali neposredno, električno ali mehansko ali s hidravliko;
– vključujejo vgrajene kazalnike preklopa zaprtega položaja ali teh kazalnikov ne vključujejo.
Ta dokument obravnava samo tipsko preskušanje.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 23553-1:2014), which has been
technically revised.
The main changes compared to the previous edition are as follows:
