... Surface-initiated rolling contact fatigue (RCF) can be triggered by dents formed due to contamination particles on raceways. To mimic this failure in this study, the surface of a steel was indented and tested in an RCF setup. This experimental technique is used to study the RCF performance...

... Chlorinated solvents, such as tetrachloroethylene and trichloroethylene, are among the most widespread groundwater and surface-water contaminants in the United States. As the construction industry continues to build larger and deeper buildings into the water table, there is a growing probability...

... Regulation and management of asbestos as a contaminant is an increasing concern for countries such as Australia. The intent of regulation is to ensure asbestos contamination is identified early and managed properly and to ensure that any remaining site contamination is recorded and managed...

... various types of contamination that were considered the potential sources of fuel present at the most probable origin. The most probable ignition mechanism identified was consistent with repetitive mechanical impact (vibrational) ignition of the contaminants. This paper summarizes the failure analysis...

... Contamination typically represents the most ignitable and flammable material in an oxygen system and poses an oxygen fire risk. Particulate generated by the materials used to preserve the cleanliness of an oxygen-cleaned part can contaminate an oxygen system. No standard was discoverable...

... Ideally, rolling bearings would always be operated in controlled clean environments and with perfect mounting conditions. However, in many cases, contamination as well as impact damage during mounting occurs. This can result in damage to the bearing raceways due to overrolling of particulate...

... the determination of solid particulate contamination. Section C is dedicated to water detection in fuel. Section D covers aviation fuel filtration, including the correct choice of filters, and the use, inspection, and maintenance of vessels and controls. Section E is dedicated to the problem of microbes that grow...

... It has been well documented in the literature that contamination within oxygen systems can create significant fire hazards. Cleanliness limits for nonvolatile residues, ranging from 10 to 500 mg/m 2 , have been established for various industries and types of oxygen systems to reduce the risk...

... Aluminum and its alloys are the preferred material in air separation units (ASUs) and are submitted to strict cleanliness requirements to avoid combustion reactions in oxygen. Linde Engineering Division has investigated the role of particle contamination for the ignition of aluminum pipes...

... Disturbance of a nonaqueous phase liquid (NAPL) contaminated sediment; for example the loading-induced consolidation after placement of a sediment cap, may result in the release of the NAPL. Organophilic clays are reported as effective media in adsorbing NAPLs and organic contaminants...

In addition to this test data, the Honeywell/Hanks lubricant life model was used to conclude that the subject grease would support our requirements. lubrication grease silicone contamination bearings space tribology Rolling Element Bearings STP 1542, 2012 Available online at www.astm.org DOI...

... British Waterways is a public corporation which owns and manages 3220 km of canals and navigable rivers in Britain. Maintaining a safe navigation channel requires the regular removal of large quantities of accumulated sediment (150,000 tons per annum) which is often contaminated with a “cocktail...

... This paper examines the potential sources of fluid contamination that may occur during the manufacture, transportation, delivery, and use of a turbine oil for power generation. A turbine oil is a very precise formulation. If it becomes polluted with other lubricants or water, its performance...

... conventional M50 and MSONiL bearings under various operating conditions. Rig tests evaluating a wide range of operating conditions, such as high load, low or boundary lubrication, heavily contaminated lubrication, and oil off were performed. Additional tests were completed to evaluate the spall propagation...

... The contaminant wear of any pump depends on the operational and the contaminant severity as well as the inherent contaminant sensitivity of the pump. In order to evaluate the contaminant sensitivity of a pump it is necessary to conduct a carefully controlled test. The primary result obtained...

... Analysis of root cause failure mechanisms in hydraulic systems suggests that poor overall system specification, leakage and contamination issues are the dominant failure contributors. The paper examines how the Russian Theory of Inventive Problem Solving, TRIZ, is beginning to be applied...
