Overview

EN ISO 4404-2:2010 - Petroleum and related products - Determination of the corrosion resistance of fire-resistant hydraulic fluids - Part 2: Non-aqueous fluids (ISO 4404-2:2010) specifies a standardized laboratory procedure to evaluate the corrosion-inhibiting properties of non-aqueous, fire‑resistant hydraulic fluids (category HFD as classified in ISO 6743‑4). The method gives a qualitative and quantitative assessment of metal corrosion when exposed to HFD fluids under controlled conditions, supporting product development, quality control and compliance activities.

Key topics and requirements

• Scope: Test applies to non‑aqueous fire‑resistant hydraulic fluids (HFD); aqueous fluids are covered in ISO 4404‑1.
• Test principle: Polished metal test pieces are immersed in test fluid at (35 ± 1) °C for (672 ± 2) h; appearance and mass change are assessed.
• Metal test pieces: Standard set includes steel, copper, brass, zinc and aluminium (composition ranges given in the standard); other metals/alloys may be substituted for specific installations.
• Specimen dimensions & preparation: Rectangular strips 100 × 20 mm, thickness 1–2 mm; polished using silicon carbide abrasive (125, 65, 37, 26 μm - equivalent to P120–P600); cleaned with heptane and handled only with forceps post‑preparation.
• Apparatus & reagents: Borosilicate beakers (400 ml), glass hooks and watch‑glasses, nylon spacers/bolts, thermostatically controlled bath or oven with uniform temperature, analytical balance (0,2 mg resolution), heptane and toluene.
• Sample size & layout: Minimum laboratory sample 3 L; typically 10 beakers (nine containing test pieces, one blank) with ~250 ml fluid each; single and paired metal exposures are used.
• Evaluation & reporting:
  • Corrosion classified on an appearance scale (0–5) for liquid and vapour zones.
  • Test fluid condition classified (0–5).
  • Mass change reported to the nearest 0.5 mg.
  • Test report must reference ISO 4404‑2:2010, product ID, results, deviations and test date.
• Safety note: The procedure may involve hazardous materials; users must follow appropriate safety practices.

Applications and users

• Hydraulic fluid manufacturers - product development and certification for corrosion resistance.
• Independent testing laboratories - standardized test method for comparative testing and QC.
• End‑users / OEMs / plant engineers - specification and selection of HFD fluids for hydraulic systems, material compatibility checks.
• Procurement and compliance teams - validation against industry standards and supplier claims.

Related standards

• ISO 6743‑4 - classification of hydraulic fluids (family H).
• ISO 4404‑1 - corrosion tests for aqueous hydraulic fluids (HFA, HFB, HFC).
• Supporting references: ISO 3170 (sampling), ISO 3819 (beakers), ISO 5272 (toluene specification).

ISO 4404-2:2010(E) © ISO 2010 – All rights reserved iii 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.
