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…

Sterilized medical devices are indispensable to doctors and surgeons around the world. Peel pouches, otherwise known as preformed sterile barrier systems, are used to keep these devices sterile during all physical handling. These pouches can be made with a wide variety of material and are produced by many different suppliers, but the trait all pouches must share is the ability to protect devices…
