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.

If a leather article such as a shoe or a glove were left next to a heater for an extended period of time, would the finish remain soft and flexible or would it change color and develop cracks within the leather finish? A new ASTM International standard will help to answer that question, giving manufacturers a clear method to predict and prevent such problems. ASTM D7912 , Test Method for…, Technical Contact:, Kadir Donmez, Leather Research Laboratory, University of Cincinnati, Cincinnati, Ohio, Phone: 513-242-6300; donmezk@uc.edu, ASTM Staff Contact:, Ashley Wiand, Phone: 610-832-9551; awiand@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9623

Increasing interest in the various uses of electrical contacts is the leading impetus for the development of a proposed new standard, ASTM WK34423 , Specification for Electrodeposited Coatings of Palladium-Cobalt Alloy for Engineering Use. The proposed standard is being developed by Subcommittee B08.08 on Metallic Coatings , part of ASTM International Committee B08 on Metallic and Inorganic…, ASTM Committee B08 Next Meeting:, May 10, 2012, May Committee Week, Phoenix, Ariz., Technical Contact:, Sheikh H. Rahman, Lean Corp., Southfield, Mich., Phone: 248-447-1526; srahman@lear.com, ASTM Staff Contact:, Diane Trinsey, Phone: 610-832-9661; dtrinsey@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9016

Wet blue and wet white are intermediate products used by tanneries that process natural hides and skins into leather. Natural fats and oils need to be largely removed from wet blue and wet white for leather processing to be done properly, but no standard had previously existed to evaluate the effectiveness of such removal. ASTM International Committee D31 on Leather has now developed such a…

A new ASTM subcommittee seeks to acknowledge the ongoing advances being made in the field of nanostructured inorganic coatings. B08.16 on Nanostructured Coatings, part of ASTM International Committee B08 on Metallic and Inorganic Coatings, is currently developing its first proposed standard, ASTM WK29468 , Specification for Galvanic Protection of Steel Using a Nanostructured Coating of 95 % Zinc…

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…

High-speed machine tool spindles and the high-pressure turbopumps that move liquid hydrogen in the space shuttle are just two examples of the uses for hybrid roller bearings. ASTM Subcommittee F34.01 on Rolling Element has now developed a standard for hybrid roller bearings, ASTM F2730/F2730M , Specification for Silicon Nitride Cylindrical Bearing Rollers. Subcommittee F34.01 is under the…
