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…

ASTM International Committee C09 on Concrete and Concrete Aggregates has recently approved two new standards, C 1611, Test Method for Slump Flow of Self-Consolidating Concrete, and C 1622, Specification for Cold-Weather Admixture Systems. Descriptions of both new standards follow. , C 1611 Test Method for Slump Flow of Self-Consolidating Concrete, The concrete industry has been using self-consolidating concrete for the past several years. A new ASTM International standard developed by Committee C09 on Concrete and Concrete Aggregates, C 1611, Test Method for Slump Flow of Self-Consolidating Concrete, will allow users to measure the consistency of self-consolidating concrete for the first time. "Because of its high fluidity, the…, C 1622 Specification for Cold-Weather Admixture Systems, Using concrete during construction in cold weather is difficult since concrete can freeze before it hardens. However, a new ASTM standard, which is the result of a project to prove that antifreeze technology for concrete is feasible, will allow for greater use of concrete during construction in cold weather. ASTM Committee C09 on Concrete and Concrete Aggregates has approved the new standard…
