A revision to an important ASTM nanotechnology standard incorporates a large-scale interlaboratory study that took place in 2008. The revised standard, ASTM E2490 , Guide for Measurement of Particle Size Distribution of Nanomaterials in Suspension by Photon Correlation Spectroscopy (PCS), is under the jurisdiction of Subcommittee E56.02 on Characterization: Physical, Chemical and Toxicological…

Localized corrosion, such as pitting, cracking or crevice corrosion, can be destructive to process equipment, but if it is detected early enough, potential damage can be minimized or avoided. A new ASTM International standard provides a means for electrochemical testing for corrosion. The new standard, G199 , Guide for Electrochemical Noise Measurement, was developed by Subcommittee G01.11 on…

ASTM International Committee F03 on Gaskets has developed and approved a new standard that can be used to evaluate gasket materials covered by ASTM F104 , Classification System for Nonmetallic Gasket Materials. The new standard, F2716 , Practice for Comparison of Nonmetallic Flat Gaskets in High Pressure Saturated Steam, is under the jurisdiction of Subcommittee F03.10 on Composite Gaskets. ASTM…

A new ASTM International standard responds to a recent emphasis by regulatory agencies that firms manufacturing drug products demonstrate the efficacy of disinfectants used in controlled environments. The standard, ASTM E2614 , Guide for Evaluation of Cleanroom Disinfectants, was developed by Subcommittee E35.15 on Antimicrobial Agents, part of ASTM International Committee E35 on Pesticides and…

The battle against cancer is being fought on many fronts. Among the most cutting-edge research efforts are attempts to engineer nanotechnology-based therapies. To aid in this endeavor, the Nanotechnology Characterization Laboratory, part of the National Cancer Institute’s Alliance for Nanotechnology in Cancer and the National Cancer Institute at Frederick, has developed methods for nanoparticle…, E2524, , Test Method for Analysis of Hemolytic Properties of Nanoparticles, -E2524 is a protocol for examining the destruction of red blood cells (hemolysis) that can lead to anemia, jaundice and other issues. All intravenously administered drugs must be examined to determine potential for hemolysis. • , E2525, , Test Method for Evaluation of the Effect of Nanoparticulate Materials on the Formation of Mouse Granulocyte-Macrophage Colonies, -E2525 describes a method for evaluating nanoparticle stimulation or inhibition of the maturation of certain bone marrow cells (macrophages). A common side effect of anti-cancer drugs is inhibition of this process, and bone marrow cells may be particularly sensitive to nano-scale material. • , E2526, , Test Method for Evaluation of Cytotoxicity of Nanoparticulate Materials on Porcine Kidney Cells and Human Hepatocarcinoma Cells, -Because studies have indicated that many nanoparticles are cleared from the body through the kidney or liver, these organs are good choices for target organ toxicity evaluation. E2526 presents a method for evaluation of nanomaterial toxicity by examining effects on kidney and cancerous liver cells. Martin Fritts is senior principal scientist at the Nanotechnology Characterization Laboratory and…

ASTM International Committee E56 on Nanotechnology has approved its first standard, E 2456 , Terminology for Nanotechnology. The new standard is under the jurisdiction of Subcommittee E56.01 on Terminology and Nomenclature. Because of the great need for a terminology document that is globally recognized and because of the cooperation of several organizations in making the document a reality,…

ASTM International Subcommittee G01.10 on Corrosion in Soils will be conducting two round robin testing procedures on Tuesday, November 14, from 9:00 a.m. to 3:00 p.m. during ASTM meetings in Atlanta, Ga. One round robin will be for the development of a new standard test method to measure the oxidation-reduction potential (redox) of soils, while the other will address precision and bias for the 4…

ASTM International Committee G01 on Corrosion of Metals has an ongoing commitment to help the oilfield and refinery industries adopt and use state-of-the-art techniques to select corrosion inhibitors. As part of this commitment, two new standards developed by Subcommittee G01.05 on Laboratory Corrosion Tests have recently been published: G 184, Practice for Evaluating and Qualifying Oilfield and…

Two subcommittees of ASTM International G01 on Corrosion of Metals have recently reorganized in order to broaden the scope of their standardization efforts. All interested parties are invited to participate in the ongoing work of Committee G01 and its subcommittees. Subcommittee G01.09, formerly on Corrosion in Natural Waters, has been renamed Corrosion of Metals in Waters to reflect a broader…
