ISO 4404-2:2003 specifies a procedure for the determination of the corrosion-inhibiting properties of non-aqueous hydraulic fluids within the category HFD, as classified in ISO 6743-4. It provides a qualitative assessment of corrosion of five of the most common metals used in the construction of hydraulic systems, but other metals and/or alloys could be added or substituted for these metals for particular installations.

<p> La présente Norme internationale prescrit une méthode d'essai qui a pour but de déterminer les effets produits sur les métaux par les fluides des catégories HFA, HFB et HFC, selon la classification de l'ISO 6743-4. Elle permet d'évaluer le pouvoir anticorrosif de ces fluides envers les éléments métalliques utilisés dans les systèmes et les installations hydrauliques. </p>
