This document specifies the operational characteristics for the various categories
of fire-resistant fluids defined by ISO 6743‑4. It includes requirements and guidelines for use of these fluids and specifies the
factors to consider when selecting a fluid from these categories for a proposed application.
This document identifies difficulties which can arise from the use of such fluids
and indicates how they can be minimized. Procedures are given for replacing one fluid
with another from a different category. Health and safety aspects when handling and
disposing of fire-resistant fluids are also covered.
This document does not apply to fire-resistant fluids used in the hydraulic systems
of commercial or military aircraft.
