Metallic tube connections for fluid power and general use - Test methods for hydraulic fluid power connections (ISO 19879:2010)
ISO 19879:2010 specifies uniform methods for the testing and performance evaluation of metallic tube connections, stud ends for ports and flange connections for use in hydraulic fluid power applications. ISO 19879:2010 does not apply to the testing of hydraulic quick-action couplings, which is covered by ISO 7241-2.
Tests outlined in ISO 19879:2010 are independent of each other and document the method to follow for each test. See the appropriate component International Standard for which tests to conduct and for performance criteria.
For qualification of the connector, the minimum number of samples specified in ISO 19879:2010 is tested, unless otherwise specified in the relevant connector standard or as agreed upon by the manufacturer and the user.
Metallische Rohrverschraubungen für Fluidtechnik und allgemeine Anwendung - Prüfverfahren für hydraulische Rohrverschraubungen in der Fluidtechnik (ISO 19879:2010)
Diese Internationale Norm legt einheitliche Verfahren für die Prüfung und die Bewertung von metallischen
Rohrverbindungen, Einschraubzapfen und Flanschverbindungen für Hydraulikanwendungen fest. Diese
Internationale Norm gilt nicht für die Prüfung von Hydraulik-Schnellkupplungen, die in ISO 7241-2 festgelegt
ist.
Die in dieser Internationalen Norm festgelegten Prüfungen sind voneinander unabhängig und beschreiben das
für die jeweilige Prüfung durchzuführende Verfahren; Prüfanforderungen und Leistungskriterien sind in der
jeweiligen Internationalen Norm über das entsprechende Bauteil enthalten.
Für den Eignungsnachweis der Verbindungsteile muss die in dieser Internationalen Norm festgelegte
Mindestanzahl an Proben einer Prüfung unterzogen werden, sofern in der entsprechenden Norm über die
Verbindungsteile nichts anderes festgelegt ist oder zwischen Hersteller und Anwender vereinbart wurde.
Raccords de tubes métalliques pour transmissions hydrauliques et pneumatiques et applications générales - Méthodes d'essai pour raccords pour transmissions hydrauliques (ISO 19879:2010)
L'ISO 19879:2010 spécifie des méthodes uniformes pour les essais et l'évaluation des performances des raccordements de tube métalliques, des éléments mâles pour orifices et des brides de raccordement destinés à être utilisés dans les applications de transmissions hydrauliques. L'ISO 19879:2010 ne s'applique pas aux essais des raccords rapides pour transmissions hydrauliques, qui font l'objet de l'ISO 7241-2.
Les essais décrits dans l'ISO 19879:2010 sont indépendants les uns des autres et documentent la méthode à suivre pour chaque essai; pour les exigences d'essai et les critères de performance, se référer à la Norme internationale appropriée couvrant le composant.
Pour la qualification du connecteur, le nombre minimal d'échantillons spécifiés dans l'ISO 19879:2010 doit être soumis à l'essai, sauf spécification contraire dans la norme de connecteurs appropriée ou accord entre le fabricant et l'utilisateur.
Kovinski cevni priključki za fluidno tehniko in splošno uporabo - Preskusne metode za hidravlične omrežne priključke (ISO 19879:2010)
Ta mednarodni standard določa enotne metode za preskus in vrednotenje delovanja kovinskih cevastih povezav, stojnih vijakov za kanale ter prirobničnih spojev za hidravlične omrežne priključke. Ta mednarodni standard se ne uporablja za preskušanje hitro delujočih hidravličnih spojev, ki so zajeti v standardu ISO 7241-2. Preskusi, ki so navedeni v tem mednarodnem standardu, niso medsebojno odvisni in navajajo metodo, ki se upošteva pri vsakem posameznem preskusu. Za preskuse, ki jih je treba izvesti, in merila učinkovitosti glejte ustrezni del mednarodnega standarda. Za kvalifikacijo konektorja se preskusi najmanjše število vzorcev, ki ga določa ta mednarodni standard, razen če je drugače navedeno v ustreznem standardu za konektorje ali dogovorjeno med proizvajalcem in uporabnikom.

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 19879 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 19879 cancels and replaces the first edition (ISO 19879:2005) of which it
constitutes a minor revision, with minor changes to 10.1, 10.2 (Table 7) and 12.2.2. (It also incorporates the
Technical Corrigendum ISO 19879:2005/Cor. 1:2007.)

ISO 19879:2010(E)
Introduction
In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an
enclosed circuit. It is required that components be designed to meet these requirements under varying
conditions. Testing of components to meet performance requirements provides a basis of assurance for
determining design application and for checking component compliance with the stated requirements.
INTERNATIONAL STANDARD ISO 19879:2010(E)
Metallic tube connections for fluid power and general use —
Test methods for hydraulic fluid power connections
WARNING — Some of the tests described in this International Standard are considered hazardous. It
is, therefore, essential that, in conducting these tests, all appropriate safety precautions be strictly
adhered to. Attention is drawn to the danger of burst, fine jets (which can penetrate the skin) and
energy release of expanding gases. To reduce the hazard of energy release, bleed air out of test
specimens prior to pressure testing. Tests shall be set up and performed by properly trained
personnel.
1 Scope
This International Standard specifies uniform methods for the testing and performance evaluation of metallic
tube connections, stud ends for ports and flange connections for use in hydraulic fluid power applications. This
International Standard does not apply to the testing of hydraulic quick-action couplings, which is covered by
ISO 7241-2.
Tests outlined in this International Standard are independent of each other and document the method to follow
for each test. See the appropriate component International Standard for which tests to conduct and for
performance criteria.
For qualification of the connector, the minimum number of samples specified in this International Standard is
tested, unless otherwise specified in the relevant connector standard or as agreed upon by the manufacturer
and the user.
