Petroleum and related products - Determination of the corrosion resistance of fire-resistant hydraulic fluids - Part 1: Watercontaining fluids (ISO 4404-1:2012)
This part of ISO 4404 specifies a test method to determine the influence on metals of fire-resistant fluids in categories HFA, HFB and HFC, as classified in ISO 6743-4. It evaluates the corrosion protection provided by these fluids towards metal components used in hydraulic systems and installations. A similar technique for fluids in category HFD is described in ISO 4404-2.

Dieser Teil der ISO 4404 legt ein Verfahren fest zur Bestimmung der korrosionshemmenden Eigenschaften von wasserhaltigen Druckflüssigkeiten der Klassen HFA, HFB und HFC, die in ISO 6743-4 klassifiziert sind. Das Prüfverfahren ermöglicht die qualitative Beurteilung der korrosionsverhindernden Eigenschaften dieser Flüssigkeiten gegenüber in der Konstruktion von Hydraulikanlagen und Anlagenkonstruktionen eingesetzten Metalle.
Ein ähnliches Prüfverfahren für Flüssigkeiten der Klasse HFD ist in ISO 4404-2 beschrieben.

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 4404-1 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.
This second edition cancels and replaces the first edition (ISO 4404-1:2001), which has been technically revised.
ISO 4404 consists of the following parts, under the general title Petroleum and related products — Determination
of the corrosion resistance of fire-resistant hydraulic fluids:
— Part 1: Water-containing fluids
— Part 2: Non-aqueous fluids

Introduction
Water-containing hydraulic fluids are used in systems where fire resistance is required due to operating
conditions. The corrosion resistance of such fluids has to be assessed in order to choose a suitable system
design and prepare maintenance instructions.

WARNING — The use of this part of ISO 4404 may involve hazardous materials, operations and
equipment. This part of ISO 4404 does not purport to address all of the safety problems associated
with its use. It is the responsibility of the user of this part of ISO 4404 to establish appropriate safety
and health practices and determine the applicability of regulatory limitations prior to use.
1 Scope
This part of ISO 4404 specifies a test method to determine the influence on metals of fire-resistant fluids in
categories HFA, HFB and HFC, as classified in ISO 6743-4. It evaluates the corrosion protection provided by
these fluids towards metal components used in hydraulic systems and installations.
A similar technique for fluids in category HFD is described in ISO 4404-2.

4 Principle
Test strips of appropriate metals, both singly and in pairs, are partially submerged in the test fluid at a specific
temperature and for a specific period. The change in mass of each test strip, its surface appearance and the
change in the appearance of the fluid during the test are determined.
NOTE 1 When assessing the corrosivity of HFAE and HFAS fluids, it may be necessary to dilute an additive concentrate
with water and the quality of the water can significantly affect the test results. The diluent, therefore, needs to be chosen
carefully and, preferably, to be representative of commercial use. The selection could be one of the test waters listed in
Annex A, deionized water or mains water as agreed between the user and the fluid supplier.
NOTE 2 The selection of the metals for corrosion testing may depend on the application and on the type of fluid being
tested. For example, aluminium may not be used in mining applications while contact between HFC fluids and zinc shall
be minimized as far as possible.
5 Reagents and materials
5.1 Acetone, analytical grade.
5.2 Heptane, analytical grade.
5.3 Water, selected from one of the following:
a) a test water of composition specified in Annex A,
b) deionized water conforming to grade 3 of ISO 3696:1987, or
c) the supply water to be used commercially.
5.4 Metal salts (listed in Table A.1), analytical grade.
6 Apparatus
6.1 Glass beakers, of capacity 400 ml, height approximately 135 mm, without a spout, conforming to
ISO 3819:1985 (see Figure 1). A maximum of ten is required for each test fluid.
6.2 Glass beaker, type H 1000, conforming to DIN 12331:1988 (of capacity 1 000 ml).
6.3 Pipette, complying with ISO 648:2008, class A.
6.4 Watch glasses (ten required), for covering the beakers (6.1), with a hole in the centre for suspending
glass hooks (6.5) (see Figures 1 and 2).
6.5 Glass hooks, allowing free suspension of the test strips in the beaker and formed in such a
