A new ASTM International standard will provide the means to quickly detect and quantify the lead concentration in toys and other children's products. The new standard, F2853 , Test Method for Determination of Lead in Paint Layers and Similar Coatings or in Substrates and Homogenous Materials by Energy Dispersive X-Ray Fluorescence Spectrometry Using Multiple Monochromatic Excitation Beams, was…

ASTM International Committee F17 on Plastic Piping Systems has just completed the development of two new standards for polypropylene sanitary sewer pipe. These new standards are the first to address both dual wall and triple wall profile designs. “Polypropylene has unique material characteristics, which make it ideal for sanitary sewer pipe applications,” says John Kurdziel, director, technical…

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…

The presence of lead in toys and other consumer products continues to make headlines. The Consumer Product Safety Improvement Act, a United States law enacted in August 2008, addresses the lead issue and makes provisions for the use of X-ray spectrometry in testing for lead content. To aid the toy and consumer products industries in using X-ray spectrometry for lead detection and meet the…
