Discussions concerning how easily test results for dimension stone test specimens can be influenced by improper or nonuniform preparation methods have led to the ongoing development of a proposed new ASTM International standard. The new standard, ASTM WK31179 , Practice for Selection and Preparation of Dimension Stone Test Specimens, is being developed by Subcommittee C18.08 on Selection of…

Petrography is routinely performed on dimension stone for many construction projects in which new stone is being used, and it is often required in technical specifications. In order to facilitate this process, ASTM International Committee C18 on Dimension Stone has developed a new standard, ASTM C1721 , Guide for Petrographic Examination of Dimension Stone. The new standard is under the…, ASTM Committee C18 Next Meeting:, April 21-22, April Committee Week, St. Louis, Mo., Technical Contact:, Michael Scheffler, Wiss, Janney, Elstner Associates Inc., Northbrook, Ill., Phone: 847-272-7400; mscheffler@wje.com, ASTM Staff Contact:, Jeff Adkins, Phone: 610-832-9738; jadkins@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8432/Dec2009

The ASTM International Proficiency Testing Center is pleased to offer a 2010 Proficiency Testing Program on Thermal Analyses of Plastics (TAP) to laboratories who need a statistical quality assurance tool that will enable them to improve and maintain a high level of performance in conducting ASTM Differential Scanning Calorimetry (DSC), Oxidative-Induction Time (OIT) by Differential Scanning…, ASTM D3418, , Standard Test Method for Transition Temperatures and Enthalpies of Fusion and Crystallization of Polymers by Differential Scanning Calorimetry (DSC);, ASTM D3850, , Standard Test Method for Rapid Thermal Degradation of Solid Electrical Insulating Materials By Thermogravimetric Method (TGA); and, ASTM D3895, , Standard Test Method for Oxidative-Induction Time of Polyolefins by Differential Scanning Calorimetry. For each test trial, laboratory participants receive two sample materials along with interactive electronic data report forms and test instructions. Using the specified ASTM program tests, participating laboratories conduct the tests of their choice that they routinely run. Upon completion of…

ASTM International Committee E37 on Thermal Measurements is seeking participation in a new subcommittee, E37.09 on Biological Calorimetry. Since its inception, the focus of Committee E37 has been the creation of methods for the calibration and use of thermal analysis instrumentation. One of the first types of thermal analysis instruments that was developed commercially on a large scale was…

Dried blood represents the greatest challenge to cleaning surgical instruments. To meet this challenge, ASTM International Committee D12 on Soaps and Other Detergents has developed a new standard, D 7225 , Guide for Blood Cleaning Efficiency of Detergents and Washer-Disinfectors. The new guide is under the jurisdiction of Subcommittee D12.16 on Hard Surface Cleaning. Water-soluble components of…
