RS ISO 12922: 2020
Lubricants, industrial oils and related products (class L) — Family H (hydraulic systems) — Specifications for hydraulic fluids in categories HFAE, HFAS, HFB, HFC, HFDR and HFDU
Abstract

This document specifies the minimum requirements of unused fire-resistant and less flammable
hydraulic fluids for hydrostatic and hydrodynamic systems in general industrial applications. It is not
intended for use in aerospace or power-generation applications, where different requirements apply. It
provides guidance for suppliers and end users of these less hazardous fluids and to the manufacturers
of hydraulic equipment in which they are used.
Of the categories covered by ISO 6743-4, which classifies the different types of fluids used in hydraulic
applications, only the following are detailed in this document: HFAE, HFAS, HFB, HFC, HFDR and HFDU.
Types HFAE, HFAS, HFB, HFC and HFDR are "fire-resistant" fluids as defined by ISO 5598. Most HFDU
fluids, while displaying an improvement in combustion behaviour over mineral oil, fall outside this
definition and are more appropriately considered as "less flammable" fluids.
