No industry standard currently exists that addresses the vacuum sealing requirements of knife-edged flanges for high vacuum applications. Existing international standards focus on interchangeability of the hardware, but do not address the reliability of the seal. ASTM International Committee E42 on Surface Analysis is now working on a proposed standard on the subject, WK21206 , Specification…

A 2002 workshop on galling wear held by ASTM International Committee G02 on Wear and Erosion provided the impetus for the development of a new standard, ASTM G196 , Test Method for Galling Resistance of Material Couples. The new standard is under the jurisdiction of Subcommittee G02.40 on Non-Abrasive Wear. According to Scott Hummel, Ph.D., associate professor, head of the department of…

Two new calibration standards for use with X-ray fluorescence equipment in the chemical analysis of hydraulic cement are now available from the Cement and Concrete Reference Laboratory (CCRL). The new standards are designated Portland Cements 167 and 168 and are vacuum-sealed to prevent moisture uptake. Robin Haupt, supervisor, CCRL proficiency sample program, says that the two new cements were…

The realization that concrete production is the result of a combination of several materials that are individually standardized, but which may interact in ways not governed by those standards, led ASTM International Committee C09 on Concrete and Concrete Aggregates to form Subcommittee C09.48 on Performance of Cementitious Materials and Admixture Combinations in 2004. The subcommittee has now…
