The ISO 12922 standard, developed by the International Standards Organization (ISO), describes the minimum requirements for non-fire resistant and less flammable hydraulic fluids for hydrostatic and hydrodynamic systems in general industrial applications. This standard is not intended for use in aerospace and power generation applications where different requirements apply. This standard is designed to provide guidance to suppliers and end users of less hazardous fluids and manufacturers of hydraulic equipment using them.

In the ISO 6743-4 standard, different types of fluids used in hydraulic applications are classified. Of these fluid types, only the following are covered within the scope of the ISO 12922 standard:
These fluids are fire-resistant and water-containing hydraulic fluids, which are defined in the ISO 5598 Fluid power systems and components standard.
Hydraulic fluids constitute a large portion of the industrial lubricants market. Mineral oil-based fluids are the most commonly used type of hydraulic fluid, but in some applications, their use poses a fire risk. In such cases, fire-resistant or less flammable fluids have been developed to enhance safety and reduce the risk to workers. However, even fire-resistant fluids can ignite at very high temperatures. The flammability behavior of the fluids defined in this standard covers a very wide range. Therefore, knowledge of the hazard level is necessary to select the appropriate fluid.
Meanwhile, the properties of these fluids can differ significantly from conventional mineral oil-based products. For example, some refractory liquids contain water.
It is recommended that this standard be considered in conjunction with the ISO 7745 standard to ensure that fire resistant hydraulic fluids will perform as expected.
Our organization, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, among lubricants, industrial oils and related products within the scope of ISO 12922 standard, HFAE, HFAS, HFB, HFC, HFDR. It also provides testing services for hydraulic fluids in the HFDU and HFDU categories.
