In light of COVID-19 (coronavirus) and growing safety concerns for members and staff, ASTM International announced today that previously scheduled April standards development meetings in Boston (March 29-April 3) and Prague (April 27-30) have been canceled. The decision was based on several factors, including, but not limited to: Continued review of information and recommendations from the U.S.…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org Release #10993

Activated carbon is processed to have small, low-volume pores that increase the surface area available for adsorption. It has applications in the medical, environmental and energy realms, among others. Since 1962, ASTM International Committee D28 on Activated Carbon has developed standards that play a pre-eminent role in how activated carbon is used. A D28 subcommittee, D28.02 on Liquid Phase…, WK47401, Xylenol Orange Dye, The xylenol orange dye test is a way to determine the relative adsorption rate of unused or reactivated carbons by adsorption of xylenol orange from aqueous solution. This is an important means for deciding which type of activated carbon to use to a specific water treatment application. “Activated carbon performance can roughly be defined as a combination of the ability to adsorb a particular…, WK47421, Particle Size Distribution, Mercury flue gas, home water filters and potable water treatment are the main applications in which powdered and fine mesh carbons are used. A proposed new test method will describe how a laser light scattering technique can determine the particle size distribution of fine mesh activated carbon. ASTM member Neal Megonnell, vice president, sales and marketing, Haycarb USA, says the proposed test…, ASTM Committee D28 Next Meeting:, April 27, April Committee Week, Anaheim, Calif., Technical Contact:, (WK47401) Adam Redding, Ph.D., Evoqua Water Technologies LLC, Northwest, Pa., tel +1.724.719.0805; adam.redding@evoqua.com and (WK47421) Neal E.

Discussions concerning how easily test results for dimension stone test specimens can be influenced by improper or nonuniform preparation methods have led to the ongoing development of a proposed new ASTM International standard. The new standard, ASTM WK31179 , Practice for Selection and Preparation of Dimension Stone Test Specimens, is being developed by Subcommittee C18.08 on Selection of…

Petrography is routinely performed on dimension stone for many construction projects in which new stone is being used, and it is often required in technical specifications. In order to facilitate this process, ASTM International Committee C18 on Dimension Stone has developed a new standard, ASTM C1721 , Guide for Petrographic Examination of Dimension Stone. The new standard is under the…, ASTM Committee C18 Next Meeting:, April 21-22, April Committee Week, St. Louis, Mo., Technical Contact:, Michael Scheffler, Wiss, Janney, Elstner Associates Inc., Northbrook, Ill., Phone: 847-272-7400; mscheffler@wje.com, ASTM Staff Contact:, Jeff Adkins, Phone: 610-832-9738; jadkins@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8432/Dec2009

Mercury emissions from flue gases in coal-fired power plants are a large source of atmospheric mercury in the United States, but no standard for determination of mercury adsorption currently exists. One promising method of controlling these emissions involves the injection of powdered activated carbon into the flue gas. A proposed new ASTM International standard would evaluate the performance of…
