Available in PDF, EPUB and Kindle. Book excerpt: Using NRL's mist flammability test apparatus, several commercial samples of 40% water-in-oil emulsion (fire-resistant hydraulic fluids) were screened for fire resistency. For comparison purposes, two other commercial fire-resistant hydraulic fluids were screened viz., a water-glycol solution and a phosphate ester. The Navy's currently used petroleum-type hydraulic fluid, 2190-TEP, was employed as the reference fluid. At the most severe conditions investigated (i.e., spray disk tangential velocity of 67.8 m/s, and fluid flow rate of 850 ml/min), none of the fire-resistant hydraulic fluids exhibited ignition leading to propagation in the presence of the propane test flame, indicating fire resistancy under these conditions. Under identical operating conditions, 2190-TEP exhibited gross ignition with propagation of flame ranging from 180 deg to 360 deg around the spinning disk, indicating it to be a potential fire hazard. The physical and chemical characteristics of the 40% water-in-oil emulsions suggest that this class of fire-resistant hydraulic fluids may be suitable replacement candidates for 2190-TEP.

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this program were to characterize thirteen candidate hydraulic fluids for flammability, miscibility, elastomer compatibility and steel-on-steel wear, to determine the feasibility of directly substituting a less flammable fluid for the MIL-H-5606 fluid currently used in most military aircraft. Evaluation in a pump test loop has been performed on MIL-H-5606B and on two of the candidate fluids. No completely nonflammable fluid is compatible with MIL-H-5606 fluid or Buna N elastomers. Three of the thirteen fluids are recommended for further consideration: Oronite 8515, Esso 3158, and Dow Corning XF-1-0302. Oronite 8515 shows some improvement in fire resistance over MIL-H-5606B and would not require operational temperature limitations if used as a replacement fluid. Reduced lubricity of highly loaded hydraulic system components (as compared to MIL-H-5606 fluid) is indicated however, by the performance of Oronite 8515 in a pump test loop. Some improvement in fire resistance over MIL-H-5606B and Oronite 8515 is shown by Esso 3158. The greater viscosity and higher pour point of the latter fluid would impose some operational temperature limitations on MIL-H-5606 fluid hydraulic systems. Dow Corning XF-1-0302 fluid shows marked improvement in fire resistance over MIL-H-5606B and is compatible with Buna N elastomers. Pump testing of this fluid is recommended to provide complete evaluation data. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted on MIL-H-5606B, Esso 3158, Oronite 8515, and Dow Corning XF-1-0302 fluids contained in tubing at 3,000 psig and in simulated hydraulic reservoirs at 30 psig. U. S. .50-caliber armor-piercing incendiary ammunition was used against these fluids. Results of the tests show a significant reduction in both amount and duration of flame for each of the candidate fluids. The vulnerability of seven structural modifications of simulated hydraulic reservoirs containing MIL-H-5606B fluid were evaluated and compared with conventional aluminum reservoirs. Two of the configurations warrant further design optimization studies. These are (1) molded-laminated-rubber construction over aluminum, and (2) glass filament-wound construction with a sheet rubber stock overwrap.

Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic fluid flammability has been evaluated for fire-resistant fluid candidates and approved fluids. Hazards directly related to the M60A1 tank have been discussed. A systematic assessment of flammability modes and ignition sources is presented. Experimental results indicate that mist flammability is more related to exposure conditions than to hydraulic fluid classes. Pool burning has been shown to be a major hazard, and the higher flash point fluids have been shown to provide a substantial margin of safety relative to conventional petroleum-base fluids. Results of ballistic tests using 20 mm HEIT projectiles demonstrated residual burning on the backstop (analogous to pool burning) only when conventional petroleum-base fluids were evaluated, otherwise, only a transient mist fireball was observed.

Available in PDF, EPUB and Kindle. Book excerpt: Experimental results are presented that indicate MIL-H-6083 (inhibited version of MIL-H-5606) could be more of a flammability hazard than some of the more recently developed fire-resistant hydraulic fluids in ground equipment vehicles. Routine laboratory experiments, as well as those designed to define mist flammability and impact dispersion, are described and the relevancy of the results obtained is discussed. Indications are that a more fire-resistant fluid could be developed to substantially reduce the fire-hazard vulnerability of ground combat vehicles. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A serious threat to life and property in many industries is the hazard of a pressurized hydraulic line rupturing, causing the escaping fluid to enter the flame of a fuel burner. The test described here simulates this danger and evaluates the fire resistance of hydraulic fluids under such conditions. The most important factor in the test equipment is the provision of a broad range of spray velocities and densities. The spray equipment is described and illustrated, and the test procedure is outlined. Data are presented from tests of one mineral oil, three water-in-oil emulsions, six water-glycol fluids, and nineteen synthetic organic fluids. Selected 35-mm colored slides illustrating the equipment and test conditions were made into black-and-white enlargements for this paper. In this process, much of the contrast was unfortunately lost. Only four synthetic organic fluids failed to ignite under one or more test conditions. All three water-in-oil emulsions tested ignited. However, when the fluid stream is of sufficient density and velocity, a typical mineral-oil hydraulic fluid will not ignite.

Book excerpt: The spray flammability characteristics of several hydraulic fluids, and mineral oil, methanol, ethanol, and n-heptane, sprayed vertically upward in the open through a pressure-jet hollow cone nozzle and stabilized by a propane-air ring burner, have been evaluated using the Factory Mutual Research Corporation (FMRC) Fire Products Collector. A spray flammability parameter (SFP) has been defined, which combines the combustion intensity of spray fires in terms of chemical heat release rate with the fluid volatility described by the critical heat flux for ignition. An SFP value has een identified at or below which a range of hydraulic fluids cannot be stabilized as spray flames using a standard flame stabilization test. Mineral oil, some hydraulic fluids, and highly volatile fluids such as n-heptane, methanol and ethanol, have high SFP values and are easy to stabilize as spray flames. SFP appears to be useful in discriminating between flammable and less flammable fluids.

This book was released on 1996 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concern about the fire resistance of hydraulic fluids by the Air Force and the rest of the Department of Defense (DoD) dates back to the introduction of the mineral oil based hydraulic fluid, MIL-H-5606 [1], into aircraft hydraulic systems. This concern has led to the development of two fire resistant hydraulic fluids that can be directly substituted into aircraft hydraulic systems that were designed to use MIL-H-5606, i.e., MIL-H-83282 [2] and MIL-H-87257 [3], and a nonflammable hydraulic fluid, MTL-H-53119 [4], that can be used only in hydraulic systems that were designed for that fluid or in subsystems originally designed for MIL-H-5606, MIL-H-83282 or MIL-H-87257, for which re-design of the components and retrofit of the system with compatible seals, if required, would be cost effective. Another fire resistant hydraulic fluid was developed for use in commercial aircraft hydraulic systems, a phosphate ester based hydraulic fluid described by Society of Automotive Engineers document AS1241, Fire Resistant Phosphate Ester Hydraulic Fluid for Aircraft The fire resistant properties of these fire resistant and nonflammable hydraulic fluids are discussed and the flammability test methods are presented.

Available in PDF, EPUB and Kindle. Book excerpt: The modification of the physical and chemical properties of various fluids developed for use as hydraulic fluids has necessitated the development or modification of tests required to evaluate the performance criteria of these fluids. The Federal Government utilized certain Federal Test Methods and ASTM flammability test procedures in fluid specification requirements to determine the relative flammability of fluids currently being developed for use as hydraulic fluids. These tests include the flash and fire points, autoignition temperature, flame propagation, high-pressure spray, and hot manifold ignition test procedures. Unfortunately, as fluid composition and applications change, new or modified tests must be developed to provide accurate assessments of the fluids' performance. This report presents the results produced by a systematic study of mist-flammability parameters that will lead to development of a standard mist-flammability test for hydraulic fluid specification purposes.
