Petroleum and related products - Determination of the oxidation stability and corrosivity of fire-resistant phosphate ester fluids

This European Standard specifies a method to assess the resistance to oxidation of a phosphate ester fluid under accelerated oxidizing conditions, together with the corrosive effect on copper and steel during ageing. The means of assessment is the change in acidity of the fluid plus absorbent water and the change in mass of test pieces of copper and steel. The precision of the test method applies to changes in acid number up to 3,0 mg KOH/g and changes in mass of up to 3 mg per test piece.
NOTE   Accelerated oxidation of fire-resistant fluids based on phosphate esters is characterized by the formation of acid constituents.
WARNING - The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Mineralölerzeugnisse und verwandte Produkte - Bestimmung der Oxidationsbeständigkeit und der Einwirkung auf Metallwerkstoffe von schwerentflammbaren Flüssigkeiten auf der Basis von Phosphorsäureestern

Diese Europäische Norm legt ein Prüfverfahren zur Begutachtung der Oxidationsstabilität für
schwerentflammbare Flüssigkeiten auf der Basis von Phosphorsäureestern fest. Diese Produkte gehören zu
der Kategorie HFDR von ISO 6743-4 [2 ] sowie zu den Kategorien TSD, TGD und TCD von ISO 6743-5 [3 ].
Hierbei erfolgt die Begutachtung anhand der während der Prüfung gebildeten Säure und anhand der
aufgetretenen Massenänderung der Prüfbleche.
Die Präzision des Prüfverfahrens gilt für Änderungen der Säurezahl bis zu 3,0 mg KOH/g und für
Massenänderungen von bis zu 3 mg pro Prüfblech. Die Bestimmung der Änderung der Säurezahl erfolgt mit
ISO 6618, ISO 6619 oder ISO 7537. Prüfergebnisse aus zwei verschiedenen Prüfverfahren sind nicht
unbedingt vergleichbar, deshalb müssen direkte Ergebnisvergleiche mit Vorsicht vorgenommen werden.
ANMERKUNG Dieses Prüfverfahren kann auch auf andere nicht-wässrige schwerentflammbare Flüssigkeiten wie z. B.
aus der Kategorie HFDU von ISO 6743-4 [2 ] angewendet werden.
WARNUNG ? Die Anwendung dieser Europäischen Norm kann den Einsatz gefährlicher Stoffe,
Arbeitsgänge und Geräte mit sich bringen. Diese Norm gibt nicht vor, alle mit ihrer Anwendung
verbundenen Sicherheitsprobleme anzusprechen. Der Anwender dieser Norm ist dafür verantwortlich,
vorher angemessene Maßnahmen in Hinblick auf Sicherheit und Gesundheit zu ergreifen und die
Anwendbarkeit einschränkender Vorschriften zu ermitteln.

Pétrole et produits connexes - Détermination de la stabilité a l'oxydation et de la corrosivité des fluides difficilement inflammables a base d'esters phosphates

Le présent document prescrit une méthode d'évaluation de la résistance a l'oxydation pour les fluides hydrauliques a base d'esters phosphates. Ces produits correspondent a la catégorie HFDR de l'EN ISO 6743 4 [2] et aux catégories TSD, TGD et TCD de l'ISO 6743 5 [3]. L'évaluation est basée sur les quantités d'acide formé et sur le changement de masse d'éprouvettes métalliques.
La fidélité de la méthode est valide pour les changements d'indice d'acide de 3,0 mg KOH/g au plus et pour les changements de masse de 3 mg au plus par éprouvette. Les changements d'acidité sont évalués par application de l'une des méthodes d'essai ISO 6618, ISO 6619 ou ISO 7537. Les résultats de deux méthodes d'essai différentes ne sont pas nécessairement compatibles, et il convient de ne pas les comparer directement sans précautions.
NOTE   L'essai est applicable a d'autres fluides non aqueux difficilement inflammables, tels que ceux décrits dans la catégorie HFDU de l'EN ISO 6743-4 [2].
AVERTISSEMENT - L'utilisation de la présente Norme européenne peut impliquer l'intervention de produits, d'opérations et d'équipements a caractere dangereux. La présente norme européenne n'est pas censée aborder tous les problemes de sécurité concernés par son usage. Il est de la responsabilité de l'utilisateur de consulter et d'établir des regles de sécurité et d'hygiene appropriées et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.

1 Scope
This European Standard specifies a method for assessing the oxidation stability of phosphate ester hydraulic
fluids. These products fall into category HFDR of EN ISO 6743-4 [2] and into categories TSD, TGD and TCD
of ISO 6743-5 [3]. The amount of acid developed during the test and the mass changes of the metal
specimens are used to assess the level of oxidation stability.
The precision of the test method applies to changes in acid number up to 3,0 mg KOH/g and changes in mass
of up to 3 mg per test piece. The change of acidity is determined using one of the test methods ISO 6618,
ISO 6619, or ISO 7537. Results from two different test methods are not necessarily compatible and direct
comparison needs caution.
NOTE This test method may also be applied to other non-aqueous fire-resistant fluids, such as those falling into
category HFDU of EN ISO 6743-4 [2].
WARNING — The use of this European Standard may involve hazardous materials, operations and
equipment. This document does not purport to address all of the safety problems associated with its
use. It is the responsibility of the user of this document to establish appropriate safety and health
practices and determine the applicability of regulatory limitations prior to use.

4 Principle
A test portion of fluid, of known acid number, is placed in a test vessel, which contains cleaned and weighed
copper and steel test pieces. The fluid and test pieces are then subjected to a temperature of 120 °C under an
oxygen flow rate of 1 l/h for 164 h. The exhausted gaseous acidic products of the oxidation are absorbed in
water, and the acid number of this phase is determined. The acid number of the test portion and the mass of
the test pieces are determined at the end of the test period, and the results are calculated as the sum of the
changes in acid number, and/or the change in mass of the individual test pieces.
5 Reagents and materials
Unless otherwise specified, reagents shall be of recognized analytical grade.
5.1 Water, conforming to the requirements of grade 3 of EN ISO 3696.
5.2 Oxygen, Minimum purity 99,4 %.
5.3 Phenolphthalein, 1 g/l ethanolic solution.
5.4 Potassium hydroxide, 0,1 mol/l ethanolic solution.
5.5 Wash solvent, use either 2,2,4-trimethylpentane or petroleum spirit with a boiling range of 60 °C to
80 °C for the metal test pieces.
5.6 Acetone.
CAUTION — Acetone is a flammable liquid and should be handled with appropriate care.
5.7 Strong oxidizing cleaning solution.
The reference oxidizing cleaning solution, on which precision was based, is chromsulfuric acid (see the
warning statement below), but alternative non-chromium containing solutions, such as ammonium persulfate
in concentrated sulfuric acid (8 g/l) have also been found to give satisfactory cleanliness. Other non-alkaline
laboratory cleaning agents that are demonstrated to give equivalent cleanliness to chromsulfuric acid, may be
used for routine analysis.
CAUTION — Chromsulfuric acid is a health hazard. It is toxic, a recognized carcinogen as it contains
Cr-VI compounds, highly corrosive and potentially hazardous in contact with organic materials. When
using chromsulfuric acid cleaning solution, eye protection and protective clothing are essential. Never
pipette the cleaning solution by mouth. After use, do not pour cleaning solution down the drain, but
