Technical Note:
Superconductive materials are metals, alloys and compounds which lose electrical resistance near absolute zero of temperature, i.e. they have infinite electrical conductivity and can carry very large electrical currents without Joule heating. The superconducting state for each material is individually characterized by a critical temperature, a critical magnetic field (which is a function of temperature) and a critical current density (which is a function of both magnetic field and temperature). Materials remain in the superconducting state provided temperature, magnetic field and current density are all less than the critical values.

CHEMICALS, METALLOIDS AND PETROLEUM PRODUCTS
Hydraulic fluids which contain as the principal ingredient(s), petroleum (mineral) oils, synthetic hydrocarbon oils, non-fluorinated silicones or fluorocarbons, and which have all of the following characteristics—
(1) A flash point of greater than 477K, (204°C, 400°F);
(2) A pour point of 239K (~34°C, -30°F) or lower;
(3) A viscosity index of 75 or greater; and
(4) Thermally stable at 616K (343°C, 650°F).
Technical Notes:

For the purpose of this Item, 'flash point' is determined using the 'Cleveland Open Cup Method' as shown in ASTM D-92 or national equivalents.
The following is the test procedure for determining thermal stability:
Twenty cc of the fluid under test shall be placed in a 46 cc type 317 stainless steel chamber containing one each of 0.5 inch (nominal) diameter balls of M-10 tool steel, 52100 steel and naval bronze (60 per cent Cu, 39 per cent Zn, 0.75 per cent Sn). The chamber shall be purged with nitrogen, sealed at atmospheric pressure and the temperature raised to 644 ±6K (371 ±6°C, 700 ±10°F) and maintained at this temperature for six hours.
The specimen will be considered thermally stable if at the completion of the above procedure all of the following conditions are met:
(1) The loss in weight of each ball is less than 0.1 mg/sq.cm of ball surface
(0.65 mg/sq.inch);
(2) The change in original viscosity as determined at 38°C is less than 25 per cent
when measured in the centistokes system of units;
(3) The total acid or base number is less than 0.40.
Boron, as follows--
(a) Boron element (metal) in all forms;
(b) Boron compounds, mixtures, and composites containing 5 per cent or more of boron (except pharmaceutical specialities packaged for retail sale), as follows:
(1) Non-ceramic boron-nitrogen compounds (e.g. borazanes, borazines and
boropyrazols);
(2) Boron hydrides (e.g. boranes), except sodium boron hydride, potassium boron
hydride, monoborane, diborane and triborane;
(3) Organoboron compounds, including metallo-organoboron compounds;
Base materials, non-composite ceramic materials; ceramic-ceramic composite materials and precursor materials for the manufacture of high temperature fine technical ceramic products, as follows-
(a) Base materials, i.e. "high purity" fine powders with uniform particle-size distribution", as follows:

The following is the test procedure for determining thermal stability:
Twenty cc of the fluid under test shall be placed in a 46 cc type 317 stainless steel chamber containing one each of .5 inch (nominal) diameter balls of M-10 tool steel, 52100 steel and naval bronze/(60 per cent Cu, 39 per cent Zn, 0.75 per cent Sn). The chamber shall be purged with nitrogen, sealed at atmospheric pressure and the temperature raised to 644 #6K (371 ±6°C, 700 ±10°F) and maintained at this temperature for six hours.
