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…

The main purpose of any grounding product is to provide a low-resistance path for fault currents to follow to the ground, which will ultimately protect the integrity of the power system and maintain a safe operating environment. ASTM International Committee B01 on Electrical Conductors is developing a proposed new standard to annealed concentric-lay-stranded copper-clad steel conductors. While…

New ASTM Committee E58 to Develop Standards That Support Engineering Investigations and Assist the Court, ASTM International, one of the largest voluntary standards development organizations (SDO) in the world, today announced the formation of ASTM Committee E58 on Forensic Engineering . Committee E58 will develop standards that promote awareness of the scientific, engineering, ethical and legal considerations inherent in forensic engineering investigations, reporting and testimony., Bringing Engineering Reason to the Dispute Resolution Process, Forensic engineering focuses on the investigation of alleged defects in materials, products, structures and components. These cases are litigated on the premise that the defects cause personal injury or damage to property. Forensic engineering investigations may help determine the causes of these events and assist the disputing parties or the court in resolving the case. Today, forensic…, Assisting the Court through Consensus Standards, ASTM Committee E58 comes together to create important standards and guides that will support the judicial process by facilitating an improved understanding of forensic engineering practices and associated technical issues. This will better enable the court to resolve disputes in a more well-informed and efficient manner, relying on deeper knowledge of the technical data presented and the sound…, E58 Standards: Guiding Forensic Engineering Practice, E58 standards will help guide forensic engineers in conducting investigations in a robust manner while protecting overall public safety. The initial scope of Committee E58 activities will be driven by subcommittees on Product Defect Incidents, Vehicular Incidents, Electrical Incidents and Industrial Processes. ASTM Committee E58 will build upon the body of work of former subcommittee E30.05 on…, Foundation Standard for the Forensic Engineering Profession, Other E58 standards will bolster the role of forensic engineering professionals in the eyes of the court and other users of these services. Consistent with this objective, Committee E58 has recently drafted a general practice document for the forensic engineering profession, titled Standard Guide for the Practice of Forensic Engineering. The goal of this standard is to further educate the court…

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…
