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 applications.
After a 35-year-absence, the natural cement industry is being revived and, along with it, a long-withdrawn ASTM International standard.
Until it closed in 1970, the Century Cement Company in Rosendale, N.Y. was the last company to manufacture natural cement. Up to that point, Rosendale had been the center of the industry, the source of more than half of all natural cement produced in the U.S. from 1817 to 1970. In the wake of Centurys shutdown, the ASTM International standard C 10, Specification for Natural Cement, fell into disuse and was discontinued in 1979.
Thomas S. Liotta, a consultant based in Charlotte, N.C., has been honored with a Committee D11 Distinguished Service Award. The committee cited Liotta "for over 35 years of dedicated and distinguished service to Committee D11 in the development and maintenance of international standards for the rubber industry and for outstanding leadership as chairman of Committee D11."
Technical Issues Facing ASTM International Committee on Declarable Substances in Materials to Be Among Topics of NIST Workshop
Technical issues with test methods and reference materials identified by ASTM Committee F40 on Declarable Substances in Materials will be among the topics discussed at a workshop hosted by the National Institute of Standards and Technology (NIST) in October. The goal of the workshop is to assist U.S. manufacturers and their supply chains in meeting new environmental regulations that restrict the use of hazardous substances in electronics and a wide range of consumer products.
ASTM International Committee B10 on Reactive and Refractory Metals and Alloys will hold its upcoming meeting Nov. 16-17, at the Mercure Hotel Ronceray Opera, in Paris, France. Committee meetings will be held Nov. 16, while presentations and a tour of the CEA/Saclay Research Center will occur on Nov. 17.
In addition to regular B10 activities, the November meeting will include special presentations on titanium, zirconium and tantalum.
Performance of Cementitious Materials and Admixture Combinations to Be Addressed by New ASTM International Joint Subcommittees
ASTM International Committee C01 on Cement and Committee C09 on Concrete and Concrete Aggregates have joined forces to form a new subcommittee, C09.48/C01.48 on Performance of Cementitious Materials and Admixture Combinations. The scope of the new subcommittee is to develop and maintain standards for investigating interactions and evaluating changes in early-age properties when various combinations of hydraulic cements, supplementary cementitious materials, other finely divided materials, water and chemical admixtures are used in cementitious mixtures.
New Slump Flow and Admixture Standards Approved by ASTM International Committee on Concrete and Concrete Aggregates
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
Standard on Descriptive Panel Performance Is Under Development in ASTM International Sensory Evaluation Committee
ASTM International Committee E18 on Sensory Evaluation of Materials and Products is currently working on a proposed new standard, WK8435, Practice/Guide for Measuring and Tracking Sensory Descriptive Panel and Panelist Performance. WK8435 will be used to assist sensory professionals in selecting, screening, and identifying training needs for new and existing panels and assessors. In addition, information in the proposed standard will allow the sensory professional to document the credibility of panelist data for their clients.
Crystallinity Standard Is Under Development in ASTM International Committee on Medical and Surgical Materials
ASTM International Committee F04 on Medical and Surgical Materials and Devices is now developing a proposed new standard, WK8619, Test Method for the Measurement of Crystallinity and Melting Point of Ultra High Molecular Weight Polyethylene via Differential Scanning Calorimetry. The proposed test method, under the jurisdiction of Subcommittee F04.15 on Material Test Methods, will focus on the measurement of the heat of fusion and the melting point of ultra high molecular weight polyethylene (UHMWPE), and the subsequent calculation of the percentage of crystallinity.
