The American Society for Testing and Materials (ASTM) is now ASTM International. It has moved into the international community to serve the needs of supporting, writing and implementing standard test methods through out the world. ASTM Committee E37 on Thermal Measurements is at the forefront of supporting new and revised methods for worldwide use. We have a committee website and are now using e-ballots to complete standards and practices in a timely manner. We actively seek international membership with active participation in our thermal analysis standard protocol development and publication. The international member does not have to travel to our meetings to actively participate; they can supply their valued input by e-ballot and e-mail to the committee. International membership in E37 follows the spirit of the ASTM International organization. We want, need and welcome your input and active contribution. International laboratories are currently involved in our global evaluation to establish precision and bias of many methods: Interlaboratory Testing [ILT], including Volatity Rate by TGA, Heat Distortion Temperature by TMA and Borchardt and Daniels Kinetics by DSC.
Committee E37 Activity Up-date
ASTM International E37 met March 11, 2002. The E37 committee is chaired by Rick Seyler, Tredegar Film Products. Following this meeting there was a Thermal Physical Measurement Workshop (focusing on heat transfer methods and applications) at the same location on March 12th. The mid-year meeting of E37 will be at ASTM International headquarters in West Conshohocken PA on Wednesday August 21, 2002. For detailed information on meeting times and agendas check the ASTM web site or call Tom O'Toole at 610-832-9739 or email him totoole@astm.org
The following are newly published or revised E37 Committee methods: E928-01 Purity by DSC; E1269-01 Specific Heat by DSC; E1858-01 Oxidative Induction Time by DSC; E1582-00 TGA temperature calibration; E2113-00 TMA Length Change Calibration.
The following methods are pending publication: E793-00 Heats of Fusion and Crystallization by DSC; E794-00 Melt and Crystallization Temperatures by DSC; E 3401 Borchardt and Daniels Kinetics by DSC.
Task Group chairpersons are needed for TMA temperature calibration and
DSC temperature calibration on cooling. Contact the ICTAC-ASTM correspondent or Tom O'Toole.
Interlaboratory tests [ILTs] on a number of test methods are about to commence or are in progress. They need national and international participation to go forward, so call and find out how you can be involved. Call Roger Blaine, Alan Riga or Tom O'Toole. Consider assisting these studies: Heats and Temperatures of Transition; Modulus by TMA; Dielectric Measurements; Volatility by TGA; and DSC calibration on cooling.
Our mission is to continuously develop or validate E37 thermal methods. We liaise with the ISO to present to the science community harmonized test methods for global implementation. The backbone of your thermal analytical measurements is standard test methods that compare and differentiate your test and characterization results. Get involved in an organization that will help you grow in your thermal science efforts.
The task group coordinator of all E37 thermal methods is Roger Blaine, TAI, 302-427-4017. Call Roger and volunteer to assist us in DSC, TGA, DMA, TMA, DEA, Thermal-physical Measurements, and more.
If you have any ASTM questions (E37 Thermal Measurements, D20 Plastics, D11 Elastomers, E30 Forensics or D02 Petrochemicals), please contact me, Dr. Alan Riga, by telephone at 216-523-7312, by mail at Department of Chemistry, Cleveland State University SI418, 2399 Euclid Avenue, Cleveland, OH 44115 USA or by email at a.riga@csuohio.edu.
