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…

Recommendations from the California Office of the State Fire Marshall and the International Wildland-Urban Interface Code have led to the development and approval of a new ASTM International standard regarding the enhancement of exterior fire protection of structures in a wildland fire. The new standard, ASTM E2707 , Test Method for Determining Fire Penetration of Exterior Wall Assemblies Using a…

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…

A new ASTM standard developed by ASTM International Committee D35 on Geosynthetics fills a need for an internationally recognized standard to ensure that EPDM sheet material received by customers is consistent regardless of the manufacturer. The new standard, D7465 , Specification for Ethylene Propylene Diene Terpolymer (EPDM) Sheet Used in Geomembrane Applications, is under the jurisdiction of…

Accepted Fire Prevention Measure to Benefit Citizen Safety Seeking to prevent accidental death and damage to property related to untended cigarettes, Finland has proposed that all cigarettes sold in the country be tested to assess their likelihood to cause fire in bedding or upholstered furniture. The regulatory proposal specifies the use of ASTM E2187 - an international standard developed by…

A new Pennsylvania law to help prevent smoking-related fires will require that cigarettes sold in the state perform well when tested using ASTM International standard E2187 , Test Method for Measuring the Ignition Strength of Cigarettes. "Careless smoking is one of the leading causes of fires, killing hundreds and injuring thousands every year," said Rep. Tim Solobay, a volunteer firefighter who…

A proposed new ASTM International standard, WK16997 Test Method for Determining the Heat Release of Materials of Low Combustibility Using a Bench Scale Oxygen Consumption Calorimeter, will be used as a fire response test for products and materials that are difficult to ignite and have relatively low rates of heat release. The proposed standard is being developed by Subcommittee E05.23 on…

A proposed new standard currently being developed by ASTM International Committee E05 on Fire Standards will establish a test protocol for assessing fire performance of decks and other horizontal exterior structures where combustibles beneath the structure can ignite. The proposed standard, WK17025 , Test Method for Evaluating the Under-Deck Fire Test Response of Deck Structures, is under the…

ASTM International Committee D35 on Geosynthetics invites all interested parties to participate in the development of a proposed new standard, WK15082 , Specification for Measuring the Asperity Height of Textured Geomembrane. The proposed standard is being developed by Subcommittee D35.10 on Geomembranes. Although asperity height is specified throughout the geosynthetic industry, a procedure to…

Three subcommittees of ASTM International Committee D35 on Geosynthetics are currently developing several proposed new standards. The topics covered in the following proposed standards are geosynthetic clay liners, geomembranes, and the development of a mechanistic-empirical design guide for pavements. Committee D35 will meet Jan. 30-Feb. 1, 2008, at the January Committee Week in Tampa, Fla.…, Subcommittee D35.04 on Geosynthetic Clay Liners, Responding to shrinkage issues involving geosynthetic clay liners, Subcommittee D35.04 has launched work on a proposed new standard, WK12239 , Test Method for Linear Dimensional Changes of Restrained Geosynthetic Clay Liners Under Cyclic Temperature and Hydration Conditions. WK12239 is an index test that covers the measurement of changes in linear dimensions of a geosynthetic clay liner that…, Subcommittee D35.10 on Geomembranes, Subcommittee D35.10 is currently developing two proposed new standards, WK14305 , Specification for Non-Reinforced PVC (Polyvinyl Chloride) Geomembrane Seams, and WK14311 , Guide for the Installation of Non-Reinforced Polyvinyl Chloride (PVC) Geomembranes. According to Mark Wolschon, engineers, specification writers, users, suppliers, manufacturers, fabricators and installers of PVC…, Subcommittee D35.01 on Mechanical Properties, There is currently a national movement to develop a mechanistic-empirical design guide for pavements. This initiative requires that the fundamental material properties for all components of the design be quantified. Subcommittee D35.01 is working toward this goal with the development of two proposed new standards, WK14361 , Test Method for Determining Small-Strain Tensile Properties of Geogrids…
