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 3.
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 part of ISO 4404 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 first edition of ISO 4404-1, together with ISO 4404-2, cancels and replaces ISO 4404:1998.
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
Annex A forms a normative part of this part of ISO 4404. Annexes B and C are for information only.
This corrected version of ISO 4404-1:2001 incorporates corrections to
 the Foreword (information regarding the document cancelled and replaced by this part of ISO 4404 has been
added), and
 the second paragraph of clause 1 (“HED” has been replaced by “HFD”).

Introduction
Water-containing hydraulic fluids are used in hydraulic systems where fire-resistant fluids are 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. The method established by this part of ISO 4404 is based on
1) th 2)
CETOP R 48H and the 7 edition of the Luxembourg report .

1) Procedure for determining corrosion resistant characteristics of water based fire resistant fluids (1984).
2) Safety and Health Commission for the Mining and other Extractive Industries, Doc. No. 4746/10/91 EN (for English version,
FR for French version), April 1994, Requirements and tests applicable to fire-resistant hydraulic fluids used for power
transmissions and control (hydrostatic and hydrokinetic), available from the Commission of the European Communities,

resistance of fire-resistant hydraulic fluids —
Part 1:
Water-containing fluids
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.
3)
A similar technique for fluids in category HFD is described in ISO 4404-2:— .
