In an action effective on Nov. 10, 2009, 15 methods contained in 10 ASTM standards are among 25 analytical methods that the U.S. Environmental Protection Agency has approved for determining contaminant concentrations in samples collected under the Safe Drinking Water Act. The methods are under the jurisdiction of Subcommittee D19.05 on Inorganic Constituents in Water, part of ASTM Committee D19…, ASTM Committee D19 Next Meeting:, Jan. 17-21, Cocoa Beach, Fla., ASTM Staff Contact:, Brynn Murphy , Phone: 610-832-9640; bmurphy@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #84 52/Jan2010

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…

Analysts in laboratories that use regression-based methods to determine uncertainty in data and customers that request such measurements will be the primary users of a new standard recently approved by ASTM International Committee D19 on Water. ASTM D7366 , Practice for Estimation of Measurement Uncertainty for Data from Regression-Based Methods was developed by Subcommittee D19.02 on Quality…

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…

Cyanide is routinely analyzed in water samples, often to demonstrate regulatory compliance; however, improper sample collection or pretreatment can result in significant positive or negative bias potentially resulting in unnecessary permit violations or undetected cyanide releases into the environment. Because of the importance and timeliness of these issues, ASTM Subcommittee D19.06 on Methods…

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…

While nearly all of the instrumentation employed in the field to measure radioactive materials or radiation exposure rates used to be in the hands of state radiological control agencies or federal government national response organizations, this is no longer the case. Now, law enforcement personnel, first responders and other professionals have radiation detection instruments, though they may not…

A strong demand from the aerospace sector has made it challenging for industry to supply heat-treated plate for both aerospace and other applications. To increase heat-treated plate production capacity, ASTM International Committee B07 on Light Metals and Alloys has developed a new standard, B 947 , Practice for Hot Rolling Mill Solution Heat Treatment for Aluminum Alloy Plate. The new standard…
