A proposed new ASTM International standard, ASTM WK22233 , Test Method for Indication of Concrete’s Ionic Conductivity, describes a five-minute nondestructive test that has the potential to replace a destructive six-hour test requiring several hours of preparation time. The proposed standard is being developed by Subcommittee C09.66 on Concrete’s Resistance to Fluid Penetration, part of ASTM…

Shrinkage that occurs during the drying process is a major cause of cracking in concrete. However, application of shrinkage-reducing admixtures in the field has been yielding positive results, and engineers have realized that admixtures can mitigate cracking. A new ASTM standard currently being developed by Subcommittee C09.23 on Chemical Admixtures will set minimum standards for an admixture to…

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…

Because of its porous nature, pervious concrete cannot be tested using standards developed for traditional concrete. In order to fill this need, ASTM International Committee C09 on Concrete and Concrete Aggregates is developing a series of proposed test methods specific to pervious. The first of these proposed standards, ASTM C1688/C1688M , Test Method for Density and Void Content of Freshly…

Two new calibration standards for use with X-ray fluorescence equipment in the chemical analysis of hydraulic cement are now available from the Cement and Concrete Reference Laboratory (CCRL). The new standards are designated Portland Cements 167 and 168 and are vacuum-sealed to prevent moisture uptake. Robin Haupt, supervisor, CCRL proficiency sample program, says that the two new cements were…

A new ASTM International standard will assist industry with a communication tool in order to comply with the European Union's Registration, Evaluation and Authorization of Chemicals, more commonly referred to as REACH. ASTM F2725, Standard Guide for European Union's Registration, Evaluation and Authorization of Chemicals (REACH) Supply Chain Information Exchange, was developed by Subcommittee F40…

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. Currently,…

The realization that concrete production is the result of a combination of several materials that are individually standardized, but which may interact in ways not governed by those standards, led ASTM International Committee C09 on Concrete and Concrete Aggregates to form Subcommittee C09.48 on Performance of Cementitious Materials and Admixture Combinations in 2004. The subcommittee has now…
