Download or read book Aerospace Fluid Power Contamination Classification for Hydraulic Fluids written by A-6C1 Fluids and Contamination Control Committee and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Standard (AS) defines contamination classes and levels for particulate contamination of hydraulic fluids and includes methods of reporting related data (Appendix A). The contamination levels selected are based on the widely accepted NAS 1638 cleanliness classes. The conversion from NAS 1638 cleanliness class specifications to AS4059 class specifications is defined. The comparison of the NAS 1638 classes to AS4059 classes and levels is provided and are defined and the differences explained (Appendix B). NAS 1638 classes based on weight of particles are not applicable to these classes and are not included. A contamination code has been added to describe the contamination levels of the fluid at the specified particle size ranges. Revision F of this standard has been prepared to include comments received from the international community, principally to simplify the coding system to either a single number contamination class that is the same as the obsolete NAS 1638 class, or as a contamination code indicating the contamination levels at a number of distinct particle size ranges. Also, normative references to using the obsolete calibration procedure ISO4402 were removed.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Information Report (AIR) presents data on normally accepted changes in physical properties and contamination levels for military hydraulic fluids used in hydraulic test stands. This information is of importance to all users of hydraulic test stands to assure the performance data obtained on these test stands for specific components will not be adversely affected by excessive changes in fluid properties or contamination levels. The data pertains to fluids conforming to specifications MIL-PRF-5606, MIL-PRF-83282, and MIL-PRF-87257. The guidelines incorporated in the AIR are the general consensus values of knowledgeable professionals. However, the experience and judgment of engineers and operators responsible for the equipment must be relied upon to determine when the hydraulic fluid is to be replaced. This document is being revised to update the specification numbers for the fluids, to add MIL-PRF-87257, and to delete the non-aerospace rust inhibited hydraulic fluids. In addition, a maximum allowable limit for barium is being added due to the problems experienced when barium gets introduced to the aircraft hydraulic system.

This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of this Aerospace Recommended Practice (ARP) covers where, when, and how often to sample hydraulic system fluid on aerospace vehicles for particulate contamination measurements.The measurement of hydraulic fluid particulate contamination is of concern to the aerospace community because of the critical importance of hydraulic equipment reliability. Contamination is always present in the system fluid, even in new unused fluid. Contamination must be below a level that will not adversely affect system operation. This ARP draws from aerospace industry experience and practice to establish criteria for fluid contamination sampling recommendations in aerospace vehicle hydraulic systems. Fluid samples can then be subjected to measurement of particulate contamination and of other harmful contaminants such as chlorinated solvents and water.

Download or read book Aerospace Chlorinated Solvent Contamination of MIL H 5606 MIL H 83282 Vehicle Hydraulic Systems written by A-6C3 Fluids Committee and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there is controversy regarding the chemical form of chlorine and its relation to harmful effects in the hydraulic fluid (i.e., chloride ions versus organic chloro-compounds versus total chlorine in all forms), it is generally agreed that total chlorine content should be measured and controlled. In the near future, the ban on the manufacture of chlorinated solvents, out of concern for depletion of the ozone layer, may in itself diminish or eliminate chlorine contamination related aircraft malfunctions. It is generally accepted that hydraulic fluid contamination should be held to a minimum under all conditions. The benefits of low contamination levels are improved performance, lower maintenance due to lower wear, corrosion and erosion, longer fluid life, longer component life, etc.Contaminants can be classified into two general types: those that are insoluble and those that are soluble in the hydraulic fluid. The insoluble solid type is most common and is usually referred to as particulate matter. Its measurement and removal have been the subject of much investigation and standardization which is well documented in technical literature. The insoluble liquid type contaminant is much less common. The resulting two phase system is often observed as hazy or cloudy fluid appearance and the recommended action is to remove the contaminated hydraulic fluid from the system.Soluble type contaminants are more difficult to detect and to determine quantitatively. They can easily escape notice, particularly when present in small amounts. Gross contamination usually results in significant changes in fluid physical properties and can be determined by such changes. Smaller amounts are difficult to detect and measure and usually require sophisticated analytical techniques -such as infrared and other spectral techniques, gas chromatography (both head space and electron capture), microcoulometry, x-ray fluorescence, etc.Generally, the presence of undesirable soluble contaminants is unknown until they have been shown to cause performance problems. Hydraulic fluid formulations contain soluble additives in base stocks giving beneficial effects on performance. The range of possible undesirable soluble contaminants can encompass innumerable materials - solids, liquids or gases.
