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…

The synthetic turf industry has been plagued with drainage performance issues for many years. Huge demand has driven the industry to grow and, as more systems have been built, the potential for issues grows. With pricing competition and inexperience being factors, how well a field system drains needs to be addressed in a consistent manner. This challenge has now been addressed with the…

Subcommittee F08.28 on Equestrian Services was formed in November 2009 and is part of ASTM International Committee F08 on Sports Equipment and Facilities. F08.28 is seeking input from equestrian trackmen and horsemen who are interested in improving the performance, uniformity and safety of equestrian surfaces, beginning with the development of the following three proposed standards. Once approved…, ASTM WK29881, Use of an Impact Analyzer to Evaluate Turfgrass Tracks Used for Horse Racing, According to Michael DePew, consulting agronomist/soil scientist, Environmental Technical Services LLC, and an F08 member, there is a need for tools for turf track evaluations that have a consistent methodology for application throughout the equestrian industry. “ ASTM WK29881 will be an evaluation tool that is intended to provide a track superintendent some of the information necessary to…, ASTM WK29879, Guide for the Laboratory Evaluation of Dirt Track Soil Material Used for Horse Racing, The purpose of ASTM WK29879 is to standardize the types of tests performed when a racing facility submits a soil sample for evaluation. The proposed standard will also cover the format of reports that result from soil tests. “A variety of soil laboratories (agronomic and engineering labs) are used to evaluate soil samples for dirt tracks,” says DePew. “Having consistent track soil evaluations…, ASTM WK27877, Terminology Relating to Thoroughbred Horse Racing Surfaces, The proposed new terminology standard will “allow track persons to communicate track surfaces/components on a consistent basis and on an ‘apples to apples’ basis,” says DePew, who also notes that ASTM WK27877 will help to reduce the use of varying terms in the equestrian industry.

A new ASTM International standard can now be used to set strength requirements for condition 0 bicycle frames. Condition 0 bicycles, typically referred to as sidewalk bikes, are designed for young children riding under the supervision of an adult. The new standard, ASTM F2843 , Specification for Condition 0 Bicycle Frames, was developed by Subcommittee F08.10 on Bicycles, part of ASTM…

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…
