Petroleum, petrochemical and natural gas industries - Venting of atmospheric and low-pressure storage tanks (ISO 28300:2008)
ISO 28300:2008 covers the normal and emergency vapour venting requirements for aboveground liquid petroleum or petroleum products storage tanks and aboveground and underground refrigerated storage tanks designed as atmospheric storage tanks or low-pressure storage tanks. Discussed in ISO 28300:2008 are the causes of overpressure and vacuum; determination of venting requirements; means of venting; selection, and installation of venting devices; and testing and marking of relief devices.
ISO 28300:2008 is intended for tanks containing petroleum and petroleum products but it can also be applied to tanks containing other liquids; however, it is necessary to use sound engineering analysis and judgment whenever ISO 28300:2008 is applied to other liquids.
ISO 28300:2008 does not apply to external floating-roof tanks.
Erdöl-, petrochemische und Erdgasindustrie - Be- und Entlüftung von Lagertanks mit atmosphährischem Druck und niedrigem Überdruck (ISO 28300:2008)
Diese Internationale Norm legt die Anforderungen für die normale Be- und Entlüftung und für die Not-Be- und Entlüftung von oberirdischen Tanks für die Lagerung von flüssigen Erdöl oder Erdölprodukten sowie von oberirdischen und unterirdischen Lagertanks mit Kühlung fest, die sowohl bei atmosphärischen Bedingungen als auch bei niedrigem Druck betrieben werden. In dieser Internationalen Norm werden die Ursachen von Über und Unterdruck, die Festlegung von Lüftungsanforderungen, die dazu erforderlichen Einrichtungen sowie Auswahl und Einbau und die Prüfung und Kennzeichnung von Be- und Entlüftungseinrichtungen behandelt.
Diese Internationale Norm ist für Tanks vorgesehen, die Erdöl und Erdölprodukte enthalten; sie gilt aber auch für Tanks mit anderen Flüssigkeiten; vor ihrer Anwendung auf andere Flüssigkeiten sollte jedoch immer eine fachmännische technische Analyse und Beurteilung vorgenommen werden.
Die vorliegende Internationale Norm gilt nicht für Tanks mit äußerem Schwimmdach.
Industries du pétrole, de la pétrochimie et du gaz naturel - Ventilation des réservoirs de stockage à pression atmosphérique et à basse pression (ISO 28300:2008)
L'ISO 28300:2008 couvre les exigences de ventilation de vapeur (gaz), normale et en situation d'urgence, des réservoirs de surface de stockage de pétrole liquide et de produits pétroliers et des réservoirs de surface et enterrés de stockage réfrigérés (frigorifiques), conçus comme réservoirs de stockage à pression atmosphérique et à basse pression. Elle aborde les causes de surpression et de dépression, la détermination des exigences de ventilation, les moyens de ventilation, le choix et l'installation des dispositifs de ventilation ainsi que les essais et le marquage des limiteurs de pression.
L'ISO 28300:2008 concerne les réservoirs contenant du pétrole et des produits pétroliers, mais peut également s'appliquer aux réservoirs contenant d'autres liquides. Il est cependant nécessaire d'utiliser une analyse et un raisonnement techniques solides lorsqu'elle est appliquée à d'autres liquides.
L'ISO 28300:2008 ne s'applique pas aux réservoirs extérieurs à toit flottant.

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 28300 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 6, Processing equipment and
systems.

Introduction
th
This International Standard was developed from the 5 edition of API Std 2000 and EN 14015:2005, with the
th
intent that the 6 edition of API Std 2000 be identical to this International Standard.
This International Standard has been developed from the accumulated knowledge and experience of qualified
engineers of the oil, petroleum, petrochemical, chemical and general bulk liquid storage industry.
Engineering studies of a particular tank can indicate that the appropriate venting capacity for the tank is not
the venting capacity estimated in accordance with this International Standard. The many variables associated
with tank-venting requirements make it impractical to set forth definite, simple rules that are applicable to all
locations and conditions.
In this International Standard, where practical, US Customary (USC) units are included in parentheses or in
separate tables, for information.
