, New ASTM Committee to Develop Standards That Will Facilitate New System Designs and Industry Growth, ASTM International, one of the largest voluntary standards development organizations (SDOs) in the world, today announced the formation of ASTM Committee F41 on Unmanned Undersea Vehicle (UUV) Systems. This important standards initiative was driven by the cooperative efforts of the United States Navy and UUV industry stakeholders to facilitate new UUV system designs and enable next-generation…, Critical Role in Oceanographic Research, Commercial and Military Applications, UUVs have a notable history dating back to the early 1980s. Early systems built on their manned submersible predecessors and helped transform oceanographic research during the decade. Used by the academic community in notable deep-sea expeditions, such as the discovery and exploration of the wreck of the Titanic, UUVs have played a critical role in ocean surveying, environmental monitoring, and…, UUV Growth and Evolution: ASTM Standards Will Help Lead the Way, Todays UUV industry includes two classes of systems: remotely operated vehicles (ROVs), which are attached to a mother-ship by a long cable; and autonomous underwater vehicles (AUVs), which operate without a tether. To better meet the challenges of emerging applications, existing UUV systems must evolve with new technology. Specific areas of need include greater interoperability among…, Fast and Efficient Standards Development Through the ASTM Process, Led by the Association for Unmanned Vehicle Systems International (AUVSI), the premier trade association for the unmanned systems industry, UUV stakeholders selected ASTM International as the SDO best suited for the development of new international industry standards. With a proven consensus process and state-of-the-art standards development infrastructure, ASTM International was best positioned…, Public/Private Sector Collaboration under the ASTM Umbrella, ASTM Committee F41 is another example of the long-standing partnership between the public and private sectors in developing consensus standards under the ASTM International process. F41 brings together technical experts from the UUV industry, federal government, trade associations and academia to develop voluntary consensus standards pertaining to UUV design, safety and performance including…

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…

ASTM International, one of the largest voluntary standards development organizations in the world, today announced the formation of a new committee to develop standards for the evaluation of materials and products relative to the restriction of certain hazardous substances. Committee F40 on Declarable Substances in Materials will address issues that could have a devastating economic impact on…, Beginning the Standardization Process, On Oct. 15, 2004, representatives from the appliance, electric tool, electronic, laboratory, instrument manufacturing, and supplier sectors affected by RoHS legislation attended a planning meeting at ASTM International Headquarters. They agreed to hold an organizational meeting to discuss the creation of a new standardization activity on declarable substances. The organizational meeting occurred…, Participation Is Open, The development of standards within Committee F40 represents a chance to help the environment while constraining unnecessary compliance costs that may damage many sectors of the world economy. If you are part of the business sectors mentioned above, participation in F40 is in your economic interest. The next meeting of Committee F40 will take place May 26-27, 2005, at ASTM International…
