MODUK - DEF STAN 91-110
Hydraulic Fluid, Fire Resistant: Aqueous Polyglycol Joint Service Designation: OX-40
|Publication Date:||30 April 2004|
This standard specifies the requirements for a HFC fire-resistant hydraulic fluid, primarily for use in shipboard hydraulic systems to reduce the risk of fire. The hydraulic systems of new ships will have been designed to use this fluid but prior approval of the Design Authority is required for use in existing Service equipment. OX-40 is not compatible with materials such as mineral oils, oil-resistant paints, polyurethane, cork, or light metals eg cadmium, zinc and aluminium alloys.
