More frequent worldwide use of asphalt-rubber binders in road building has increased the need for rotational viscotesters, which are used to ensure proper quality control and assurance. While an appropriate standard for viscotesters does not currently exist, a proposed new ASTM standard will answer this need. The proposed standard, WK25108 , Test Method for Measurement of Apparent Viscosity of…

The presence of lead in toys and other consumer products continues to make headlines. The Consumer Product Safety Improvement Act, a United States law enacted in August 2008, addresses the lead issue and makes provisions for the use of X-ray spectrometry in testing for lead content. To aid the toy and consumer products industries in using X-ray spectrometry for lead detection and meet the…

Many factors, such as traffic, drainage, structure and climatic variations, impact the field performance of asphalt concrete. However, asphalt concrete performance has been more accurately predicted when laboratory material properties are known, so ASTM International Committee D04 on Road and Paving Materials has approved a new standard, ASTM D7460 , Test Method for Determining Fatigue Failure of…

Current methods for determining bulk specific gravity of aggregate are often time-consuming and not ideal for quality control checks during construction. However, a new ASTM International standard provides a fast method for determining the consistency of aggregate properties that are used in asphalt and concrete mixtures. Committee D04 on Road and Paving Materials has approved ASTM D7370…

Developing Standards for REACH, RoHS and Similar Regulations Implementation, ASTM International Committee F40 on Declarable Substances in Materials will meet April 15-17, 2008, at the Renaissance Hotel in Brussels, Belgium. The purpose of the meeting is to continue developing the international standards needed in response to REACH and RoHS implementation. , REACH, RoHS and ASTM Committee F40, The European Union’s Restriction of Hazardous Substances (RoHS) directive and Registration, Evaluation and Authorization of Chemicals (REACH) system — designed to help improve human health and the environment — affect companies and consumers throughout the global supply chain for manufactured goods. ASTM International Committee F40 develops the standards to help stakeholders with the…, Meeting Highlights, On Tuesday, 15 April, , Subcommittee F40.01 on Test Methods will review five proposed work items, among them WK11200 , Standard Test Method for Identification and Quantification of Lead, Mercury, Cadmium, Chromium, and Bromine in Polymeric Material Using Energy Dispersive X-ray Spectrometry (EDXRF). WK11200 will assist industry throughout the polymeric supply chain by testing the materials at the raw material level.…, On Wednesday, 16 April, , Subcommittee F40.02 on Management Practices and Guides will continue drafting WK15430 , Standard Guide for European Union's Registration, Evaluation, and Authorization of Chemicals (REACH) Supply Chain Information Exchange. WK15430 is being developed to assist industry with communications through the supply chain for REACH compliance. Providing a standard way to communicate will save money and…, On Thursday, 17 April, , A workshop on REACH will be held. Workshop speakers include meeting co-sponsor and Committee F40 vice chairman Taco Van Der Maten of PANalytical; meeting co-sponsor Dirk Wissmann of SPECTRO Analytical Instruments, a division of AMETEK Inc.; and Kristina Nordlander in Sidley Austin’s Brussels office. A question and answer session will cap off the event. , Open Participation, Participation in ASTM Committee F40 is open to all interested stakeholders. The committee draws on the expertise of an international group of stakeholders representing trade associations, manufacturers, government regulators, consumers and academia, and encourages and promotes publications, research and other tools to facilitate RoHS and REACH compliance and standards development.
