Metallic tube connections for fluid power and general use - Part 1: 24 degree cone connectors (ISO 8434-1:2007)
ISO 8434-1:2007 specifies the general and dimensional requirements for 24° cone connectors using cutting ring and O‑ring seal cone (referred to as DKO) suitable for use with ferrous and non‑ferrous tubes with outside diameters from 4 mm to 42 mm inclusive. These connectors are for use in fluid power and general applications within the limits of pressure and temperature specified in ISO 8434-1:2007.
It also specifies a performance and qualification test for these connectors.
Metallische Rohrverschraubungen für Fluidtechnik und allgemeine Anwendung - Teil 1: Verschraubungen mit 24°-Konus (ISO 8434-1:2007)
Dieser Teil der ISO 8434 legt allgemeine und maßliche Anforderungen an 24°-Rohrverschraubungen mit Schneidring und O-Ring-Dichtkegel (kurz als DKO bezeichnet) fest, die für die Verwendung mit Stahlrohren und Rohren aus Nichteisenmetallen mit einem Außendurchmesser von 4 mm bis einschließlich 42 mm ge¬eignet sind. Diese Rohrverschraubungen sind für die Fluidtechnik und allgemeine Anwendungen in dem in diesem Teil der ISO 8434 festgelegten Temperatur- und Druckbereich vorgesehen.
Sie sind für die Verbindung von Rohren mit geraden Enden und Schlaucharmaturen an Einschraublöchern nach ISO 6149 1, ISO 1179 1 und ISO 9974 1 vorgesehen. (Festlegungen für Schlaucharmaturen, siehe ISO 12151 2).
Diese Rohrverschraubungen sorgen in Hydraulikanlagen mit Arbeitsdrücken nach Tabelle 1 für Verbindungen mit vollem Durchfluss. Da der Druck, bei dem eine Anlage zufriedenstellend funktionsfähig ist, durch viele Faktoren beeinflusst wird, sind diese Werte nicht als abgesicherte Mindestwerte zu betrachten. Für jeden Anwendungsfall müssen ausreichend Prüfungen durchgeführt werden, die sowohl vom Anwender als auch vom Hersteller zu bewerten sind, um sicherzustellen, dass die geforderten Leistungsstufen eingehalten werden.
ANMERKUNG 1 Für Neukonstruktionen in hydraulischen Anlagen der Fluidtechnik gelten die Anforderungen in 9.6. Sofern nach den Anforderungen für den jeweiligen Anwendungsfall die Verwendung von Elastomerdichtungen zulässig ist, werden für die Rohrverschraubung Ausführungen nach Internationalen Normen mit Elastomerdichtungen bevorzugt.
ANMERKUNG 2 Für Anwendungsfälle außerhalb des in dieser Norm festgelegten Druck- und/oder Temperaturbereichs, siehe 5.4.
Dieser Teil der ISO 8434 legt ferner eine Prüfung der Funktionsfähigkeit und Eignung dieser Rohr¬verschraubungen fest.
Raccordements de tubes métalliques pour transmissions hydrauliques et pneumatiques et applications générales - Partie 1: Raccords coniques à 24 degrés (ISO 8434-1:2007)
L'ISO 8434-1:2007 spécifie les exigences générales et dimensionnelles relatives à la conception et à la performance des raccords à compression à 24° utilisant une bague de compression et un cône à joint torique (référencé comme DKO) qui sont adaptés à l'utilisation avec des tubes en métaux ferreux et non ferreux de diamètre extérieur de 4 mm à 42 mm inclus. Ces raccords sont utilisés dans les transmissions hydrauliques et pneumatiques et les applications générales dans les limites de pression et de température spécifiées dans l'ISO 8434-1:2007.

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 8434-1 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 4,
Connectors and similar products and components.
This second edition of ISO 8434-1 cancels and replaces ISO 8434-1:1994 and ISO 8434-4:1995, of which it
