The need for a consensus standard targeting the measurement of gaseous hydrocarbons and other components of gaseous streams allowing users to better comply with U.S. Environmental Protection Agency’s greenhouse gas regulation provided the impetus for the development of a proposed new ASTM International standard meeting this need. ASTM WK33788 , Test Method for Determination of Hydrocarbons and…

A new ASTM International standard, adopted from an American Concrete Institute test method, will be used to help ensure the safety of construction projects. ASTM C1741 , Test Method for Bleed Stability of Cementitious Post-Tensioning Tendon Grout, is under the jurisdiction of Subcommittee C09.41 on Hydraulic Cement Grouts , part of ASTM International Committee C09 on Concrete and Concrete…

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 Committee G02 on Wear and Erosion is including a field trip in the plans for its Dec. 8-9 meeting in Jacksonville, Fla. Committee members will be visiting the Tribology Laboratory in the mechanical engineering department at the University of Florida in Gainesville. The Tribology Laboratory is actively involved in a wide variety of tribological research and tribology education projects. The…

A new ASTM standard will be useful to slide and engine companies, as well as makers of bushing materials, in studies that involve the measurement of system friction forces. The new standard, ASTM G203 , Guide for Determining Friction Energy Dissipation in Reciprocating Tribosystems, was developed by Subcommittee G02.50 on Friction, part of ASTM International Committee G02 on Wear and Erosion.…

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…

Subcommittee G02.10 on Erosion by Solids and Liquids, part of ASTM International Committee G02 on Wear and Erosion, is interested in hearing from anyone who uses cavitation erosion testing in their work. The objective of this survey is to help the subcommittee determine the current degree of interest in and importance of cavitation erosion test methods. The subcommittee is especially interested…
