Petroleum and related products - Determination of emulsion stability of fire-resistant fluids - Part 2: Fluids in category HFB (ISO 20783-2:2003)

ISO 20783-2:2003 specifies three test methods to assess the stability of emulsions within the category HFB, as defined in ISO 6743-4.
Method A describes a method for the determination of stability during storage at ambient temperature [(20 ± 2) °C] and is applicable to HFB and HFB.LT fluids.
Method B describes a method for the determination of stability during storage at medium temperature [(70 ± 2) °C] and is again applicable to HFB and HFB.LT fluids.
Method C describes a method for the determination of stability during storage at low temperature [(-10 ± 2) °C] and is applicable only to HFB.LT fluids.

Mineralölerzeugnisse und verwandte Produkte - Bestimmung der Emulsionsstabilität von schwerentflammbaren Druckflüssigkeiten - Teil 2: HFB-Flüssigkeiten (ISO 20783-2:2003)

Dieser Teil von ISO 20783 legt drei Prüfverfahren zur Bestimmung der Emulsionsstabilität für Flüssigkeiten der in ISO 6743-4 (siehe [4] im Literaturverzeichnis) definierten Kategorie HFB fest.
Verfahren A legt die Bestimmung der Emulsionsstabilität bei der Lagerung bei Raumtemperatur [(20 ± 2) °C] fest und ist anwendbar auf Flüssigkeiten vom Typ HFB und HFB.LT.
Verfahren B legt die Bestimmung der Emulsionsstabilität bei der Lagerung bei mittlerer Temperatur [(70 ± 2) °C] fest und ist ebenfalls anwendbar auf Flüssigkeiten vom Typ HFB und HFB.LT.
Verfahren C legt die Bestimmung der Emulsionsstabilität bei der Lagerung bei niedrigen Temperatur fest und ist ebenfalls anwendbar nur auf Flüssigkeiten vom Typ HFB.LT.
Dieses Prüfverfahren ist im 7. Luxemburger Bericht spezifiziert ) .

ISO 20783-2:2003(E)
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 20783-2 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.
ISO 20783 consists of the following parts, under the general title Petroleum and related products —
Determination of emulsion stability of fire-resistant fluids:
