MIL-H-19457 Intended use:
The material covered by this specification is intended
for use as a fire-resistant power transmission fluid for accumulator loaded
shipboard hydraulic systems which operate at pressures exceeding 600 lb/in2
gauge. This fluid may soften and deteriorate most commonly used paints,
elastomers and electrical insulating materials, and therefore requires the use of
compatible materials as necessary. Special handling procedures are required for
use with this fluid. This material is not satisfactory for use on
board submarines.
MIL-H-19457 Scope:
This specification covers the requirements of fire-resistant
hydraulic fluid for hydraulic systems which are accumulator loaded and operate
above 600 pounds per square inch (lb/in2) gauge.
MIL-H-19457 Composition
Material:
The fluid shall be a stable, homogeneous formulation of
tertiary butylated triphenyl phosphate and such other ingredients as are required
for conformance to this specification. Additives to permit conformance to the
viscosity requirements of the fluid are not permitted.
MIL-H-19457 Corrosion:
The fluid shall not produce visually evident pitting,
etching, or a weight change in excess of 0.2 mg/cm2 of brass, zinc, aluminum, or
steel>
The fluid shall be furnished in 1- and 5-gallon cans and 55-
gallon drums as specified
MIL-H-19457 Toxicity:
The hydraulic fluid shall have no adverse effect on the
health of personnel when used for its intended purpose. The fluid shall contain
no components which produce noxious vapors or mists in such concentrations as to
be a threat to the health of personnel during use under conditions of adequate
ventilation while exercising caution to avoid prolonged contact with the skin
Questions pertinent to this effect shall be referred by the contracting activity
to the Naval Medical Command (NAVMEDCOM), who will act as an advisor to the
contracting agency.
Acid number,
Tertiary butylated triphenyl phosphate,
Tricresyl phosphate
The fluid shall have a triorthocresyl phosphate (TOCP) content not greater than 0.2 percent
