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…

Conventionally processed powder metallurgy materials often exhibit open microporosity at the surface. While it is a natural part of the process, this microporosity can affect the measurement of surface finishes. To cover this and other issues that arise from measuring the surface finish of powder metallurgy, ASTM International Committee B09 on Metal Powders and Metal Powder Products has developed…

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…
