Petroleum and related products - Determination of the flammability characteristics of fluids in contact with hot surfaces - Manifold ignition test (ISO 20823:2003)

This International Standard specifies a method to determine the relative flammability of fluids when contacted with a hot metal surface
at a fixed temperature, but it is also possible to gauge fluid ignition temperatures by adjustment of mainfold temperature. The primary use is to assess the resistance to ignition of fire-resistant hydraulic fluids which are, by definition, difficult to ignite. The use of this International Standard with other types of more flammable fluids will significantly increase the hazards of this procedure. This procedure is specified in ISO 12922 as an indicator of fire-resistance.

Mineralölerzeugnisse und verwandte Produkte - Bestimmung der Entflammbarkeits-Charakteristik von Flüssigkeiten bei Kontakt mit heißen Oberflächen - Zündverfahren (ISO 20823:2003)

Diese Internationale Norm beschreibt ein Prüfverfahren zur Bestimmung der relativen Entflammbarkeit von Flüssigkeiten beim Auftreffen auf heiße, metallische Oberflächen bei einer fest eingestellten Temperatur. Durch Anpassung der Oberflächentemperatur besteht ebenfalls die Möglichkeit, die Zündtemperatur von Flüssigkeiten anzuzeigen.
Die Hauptanwendung besteht in der Bewertung der Zündhemmung schwerentflammbarer Druckflüssigkeiten, welche durch Definition schwer entzündbar sind.
Diese Norm kann auch für andere Typen entflammbarer Flüssigkeiten bei niedrigeren Oberflächentemperaturen angewendet werden. Dabei ist jedoch mit einem deutlich zunehmenden Anstieg der Brandgefahr während der Prüfung zu rechnen.
ANMERKUNG   Dieses Prüfverfahren ist in ISO 12922:1999, Lubricants, industrial oils and related products (class L) - Family H (Hydraulic systems) - Specifications for categories HFAE, HFAS, HFB, HFC, HFDR and HFDU als Prüfung der Schwerentflammbarkeit vorgeschrieben

Pétrole et produits connexes - Détermination des caractéristiques d'inflammabilité de fluides au contact de surfaces chaudes - Essai d'inflammation sur métal chaud (ISO 20823:2003)

L'ISO 20823:2003 spécifie une méthode d'essai qui a pour but de déterminer les caractéristiques d'inflammabilité relative des fluides quand ils sont mis au contact d'une surface métallique chaude à une température définie, mais il est également possible d'évaluer la température d'inflammation d'un fluide en ajustant la température du métal.
Elle est particulièrement utilisée pour évaluer la résistance à l'inflammation des fluides hydrauliques difficilement inflammables, qui sont par définition difficiles à enflammer.
Elle peut être utilisée avec d'autres types de fluides plus inflammables à des températures de surface inférieures, mais ceci peut accroître considérablement les risques liés à la méthode.

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 20823 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.

INTERNATIONAL STANDARD ISO 20823:2003(E)

Petroleum and related products — Determination of the
flammability characteristics of fluids in contact with hot
surfaces — Manifold ignition test
WARNING — The use of this International Standard may involve hazardous materials, operations and
equipment. This International Standard does not purport to address all of the safety problems
associated with its use. It is the responsibility of the user of this International Standard to establish
appropriate safety and health practices and determine the applicability of regulatory limitations prior
to use.
1 Scope
This International Standard specifies a test method to determine the relative flammability of fluids when
contacted with a hot metal surface at a fixed temperature, but it is also possible to gauge fluid ignition
temperatures by adjustment of the manifold temperature.
It is primarily used to assess the resistance to ignition of fire-resistant hydraulic fluids which are, by definition,
difficult to ignite.
It may be used with other types of more flammable fluids at lower surface temperatures, but this could
significantly increase the hazards of this procedure.
NOTE The procedure given in this International Standard is specified in ISO 12922:1999, Lubricants, industrial oils
and related products (class L) — Family H (Hydraulic systems) — Specifications for categories HFAE, HFAS, HFB, HFC,
HFDR and HFDU.

ISO 3170:— , Petroleum liquids — Manual sampling
3 Principle
A 10 ml test portion of fluid is dropped from a predetermined height and at a specified rate, onto a tube heated
to 700 °C, or another temperature in a series. The resulting spray is examined for flash or burn, both on the
tube and after dripping from the tube.
