A new ASTM International standard will have applications in a variety of factories, on artificial turfs and playing surfaces, and even in the classroom. The new standard, G194 , Test Method for Measuring Rolling Friction Characteristics of a Spherical Shape on a Flat Horizontal Surface, was developed by Subcommittee G02.50 on Friction, part of ASTM International Committee G02 on Wear and Erosion…

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…

Sterilized medical devices are indispensable to doctors and surgeons around the world. Peel pouches, otherwise known as preformed sterile barrier systems, are used to keep these devices sterile during all physical handling. These pouches can be made with a wide variety of material and are produced by many different suppliers, but the trait all pouches must share is the ability to protect devices…

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…

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…

Although ASTM International Committee E56 on Nanotechnology was just established this year, it has already begun an ambitious program of developing new standards. Committee E56 is currently developing the following proposed standards, which deal with environmental safety issues, hemolytic properties and particle size measurement. Interested parties are invited to participate in the development of…, WK8985, Guide for Handling Unbound Engineered Nanoparticles in Occupational Settings, Academic, government and industrial laboratories are currently performing nanotechnology research and development and the scope and breadth of this work is expected to grow dramatically. Manufacturing processes involving nanomaterials have begun and commercially available nano-based products have been introduced. All of this activity in the nanotechnology realm has created the need for the…, WK8997, Practice for Analysis of Hemolytic Properties of Nanoparticles, Subcommittee E56.02 on Characterization has begun working on proposed new standard WK8997, Practice for Analysis of Hemolytic Properties of Nanoparticles. This proposed standard would provide a suitable procedure for establishing the safety of nanoparticulate materials that will be used in vivo , such as nanoparticles for therapeutics and diagnostics. "Nanotechnology products will be used in…, For further technical information, contact Scott McNeil, director, Nanotechnology Characterization Laboratory, Frederick, Md. (phone: 301/846-6939; mcneils@ncifcrf.gov )., WK8705, Measurement of Particle Size Distribution of Nanomaterials in Suspension by Photon Correlation Spectroscopy (PCS), Subcommittee E56.02 was formed to answer questions regarding characterization, such as size and shape of materials. Another proposed new standard under the jurisdiction of Subcommittee E56.02 is WK8705, Measurement of Particle Size Distribution of Nanomaterials in Suspension by Photon Correlation Spectroscopy (PCS), which deals with the vital issue of size characterization. The purpose of the…
