A long-standing need to standardize terminology within the additive manufacturing industry has now been met with a new ASTM International standard, ASTM F2792 , Terminology for Additive Manufacturing Technologies. The new document is the first approved standard under the jurisdiction of ASTM Committee F42 on Additive Manufacturing Technologies, which was formed in 2009. Terry Wohlers, principal…, Technical Contact:, Terry Wohlers, Wohlers Associates Inc., Fort Collins, Colo., Phone: 970-225-0086; tw@wohlersassociates.com, ASTM Staff Contact:, Pat Picariello, Phone: 610-832-9720; ppicarie@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8426/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…

New Advanced Ceramics Standards from ASTM Cover Fracture Mirror Size Analysis, Tensile Strength DataSubcommittee C28.01 on Mechanical Properties and Performance, part of ASTM International Committee C28 on Advanced Ceramics, has recently approved two new standards, ASTM C1678 , Practice for Fractographic Analysis of Fracture Mirror Sizes in Ceramics and Glasses, and ASTM C1683 , Practice for Size Scaling of Tensile Strengths Using Weibull Statistics for Advanced Ceramics., ASTM C1678 —Bringing Consistency to Fracture Mirror Size Analysis, Fracture mirror size analysis is a powerful quantitative tool for the interpretation of broken ceramic and glass articles. While this type of analysis can be used to determine the stress in a part at the instant of fracture, inspection and interpretation procedures have often varied, resulting in uncertainty in stress estimates. ASTM C1678, Practice for Fractographic Analysis of Fracture Mirror…, ASTM C1683 —Scaling Strength Values, ASTM C1683, Practice for Size Scaling of Tensile Strength Using Weibull Statistics for Advanced Ceramics, provides methodology to convert fracture strength parameters estimated from data obtained with one test geometry to strength parameters representing other test geometries. Stephen Duffy, chair of civil engineering, Cleveland State University, and C28 member, says that companies producing…

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…
