Petroleum and related products - Determination of the extreme-pressure and anti-wear properties of fluids - Four ball method (European conditions) (ISO 20623:2003)
ISO 20623:2003 specifies procedures for the measurement of the extreme-pressure (EP) and anti-wear properties of lubricating oils and fluids by means of the four ball machine. The conditions of test are those that apply in Europe and other areas that have similar electrical supply characteristics (200 V to 250 V, 50 Hz). In North America, the conditions of test are slightly different, but provide a similar ranking of the lubricating properties of fluids. The test conditions are not intended to simulate particular service conditions, but to provide information over a range of standard conditions for the purpose of research, development, quality control and fluid ranking. The output is used in lubricant specifications.
Minaralölerzeugnisse und verwandte Produkte - Bestimmung der EP-Eigenschaften und Verschleißkennwerte von Flüssigkeiten - Verfahren mit dem 4-Kugel-Apparat (Europäische Bedingungen) (ISO 20623:2003)
Diese Internationale Norm beschreibt ein Verfahren zur Bestimmung von Schweißkraft [EP-Verhalten] und Verschleißkennwerten von Schmierölen und Flüssigkeiten mit Hilfe des Vierkugel-Apparates. Die Prüfbedingungen sind so ausgelegt, dass das Prüfverfahren in Europa und anderen Gebieten mit vergleichbaren Stromversorgungen (200 V bis 250 V, 50 Hz) unmittelbar eingesetzt werden kann. In Nordamerika liegen leicht abweichende Voraus-setzungen für den Test vor, die aber trotzdem eine vergleichbare Klassifiizierung der Schmierstoffeigenschaften der untersuchten Flüssigkeiten ermöglichen. Es ist nicht beabsichtigt, durch die Prüfbedingungen ein besonderes Betriebsverhalten zu simulieren, sondern Informationen über einen Bereich von Standardbedingungen für Forschungszwecke, für die Schmierstoffentwicklung, zur Qualitätskontrolle und zur Klassiifizierung von Flüssigkeiten bereitzustellen. Die Ergebnisse werden zur Spezifizierung von Schmierstoffen verwendet.
Dies Verfahren ist im 7. Luxemburger Bericht festgelegt worden ).
Pétrole et produits connexes - Détermination des propriétés extrême pression et anti-usure des fluides - Essai à quatre billes (conditions européennes) (ISO 20623:2003)
L'ISO 20623:2003 spécifie des méthodes de mesurage des propriétés extrême pression (EP) et anti-usure d'huiles lubrifiantes et de fluides au moyen de la machine à quatre billes. Les conditions d'essai sont celles qui s'appliquent en Europe et dans les autres pays dont les caractéristiques de secteur sont similaires (200 V à 250 V, 50 Hz). Les conditions d'essai pour l'Amérique du Nord sont légèrement différentes. Elles conduisent néanmoins à un classement similaire des propriétés lubrifiantes des fluides. Les conditions d'essai ne visent pas à simuler des conditions d'utilisation particulières, mais à fournir une variété de conditions normalisées pour la recherche, le développement, le contrôle qualité et la comparaison de fluides. Les résultats sont utilisés dans des spécifications de lubrifiants.

ISO 20623:2003(E) iv © ISO 2003 — All rights reserved 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 20623 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.
