Piston ring/liner interface can contribute as much as half the total friction loss in internal combustion engines, with the resulting wear leading to reduced energy efficiency and raised emissions. A new ASTM International standard provides a method to more accurately measure small amounts of wear on curved piston ring segments and their counterfaces after lubricated bench-scale testing. “Coupled…

ASTM International Committee E07 on Nondestructive Testing has recently approved three new standards on phased arrays, polymer matrix composites for aerospace applications and digital imaging. The committee will be meeting in Plantation, Fla., on Jan. 24-28 and welcomes participation in its standards developing activities., Ultrasonic Methods, Thousands of portable phased array units, used for weld inspections, have now been sold worldwide. There are many benefits to these devices, including speed, cost, imaging, flexibility and setups, along with no radiation, licensing or contamination. Despite these advantages, there was not a universal inspection procedure for phased array inspection of welds. A new standard, E2700 , Practice for…, Specialized NDT Methods, A new guide gives an introductory overview that describes how mature and established nondestructive testing methods that are routinely used by industry are applied specifically to the characterization of polymer matrix aerospace composites. E2533 , Guide for Nondestructive Testing of Polymer Matrix Composites Used in Aerospace Applications, is under the jurisdiction of Subcommittee E07.10 on…, Digital Imaging and Communication in Nondestructive Evaluation, A new standard developed by Subcommittee E07.11 on Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) will fill a need in the nondestructive testing industry for a transparent and industry standard data format with which to store digital inspection data. E2663 , Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Ultrasonic Test Methods…, WK17435,, Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for X-Ray Computed Tomography (CT) Test Methods;, WK17436, , Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Digital Radiographic (DR) Test Methods;, WK20537, , Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Eddy Current Test Methods; and, WK22505,, Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Computed Radiography (CR) Test Methods.

Three primary factors define the success or failure of any attempt to forcibly penetrate a security fence system: the tools and devices employed, the number of aggressors and their level of sophistication. A newly approved ASTM International standard can be used to measure the resistance of fence systems to such an attempt. ASTM F2781 , Practice for Testing Forced Entry Resistance of Security…, ASTM Committee F14 Next Meeting:, Feb. 16, 2010 , in conjunction with American Fence Association, FENCETECH 2010, Orlando, Fla., Technical Contact:, Charles Naegele, P.E., Allied Consulting Inc., Clarks Summit, Pa., Phone: 570-586-7260; canaegele@aol.com, ASTM Staff Contact:, Thomas O’Toole, Phone: 610-832-9739; totoole@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8427/Dec2009

ASTM International Committee D03 on Gaseous Fuels invites all interested parties to participate in their standards developing activities. Proposed new standards currently being developed by subcommittees within D03 include ASTM WK24874, Test Method for the Determination of Moisture Vapor Concentration in Natural Gas and by Tunable Diode Laser Spectroscopy (TDLAS), and ASTM WK24875 , Practice for…, Tunable Diode Laser Spectroscopy, The proposed new standard, ASTM WK24874 , is being developed at the request of several gas companies that use TDLAS analyzers for the measurement of moisture in natural gas. While TDLAS has become a popular type of gas analysis, no specific standard currently exists for its use. ASTM WK24874 is under the jurisdiction of Subcommittee D03.12 on On-Line/At-Line Analysis of Gaseous Fuels. According…, Siloxanes, While biofuel from landfills and sewage digestion has been used as fuel for local gas turbine engines, it is necessary to hold the content of siloxanes within the fuel down to 50 parts per billion. Siloxanes that can coat the turbine under working conditions are converted to an abrasive silicone dioxide coating that greatly reduces the lifetime of the engine. ASTM WK24875 is currently being…

Sulfur compounds are known for their smell, but odor isn’t the only issue sulfur compounds create, at least when found in various kinds of gas. Too much sulfur in gaseous fuels, such as natural gas, petroleum gases and biogases, can be corrosive to equipment, result in regulatory issues, and can inhibit or destroy catalysts used in gas processing and utilization equipment. However, sulfur gases…
