ASTM International’s Committee D09 (Electrical and Electronic Insulating Materials) invites anyone to join in developing a new standard to help maintain the integrity of cables during an emergency such as a fire. Specifically, the proposed standard (WK52230, Test Method for Determination of Acid Gas Content of Wire and Cable Insulation or Jacket Material) will help determine the halogen content…, ASTM Committee D09 Next Meeting:, April 14-15, 2016, April Committee Week, San Antonio, Texas, Media Inquiries:, Nathan Osburn, tel +1.610.832.9603; nosburn@astm.org, Technical Contact:, Larry Ingram, Williamsport, Pa., tel +1.570.916.8448; larry77151@comcast.net , ASTM Staff Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #9960

ASTM grain size is a property written into many specifications for metals, with finer grain sizes generally indicating better mechanical properties, such as formability. While measuring certain materials for such properties can be difficult, electron backscatter diffraction can provide precise determinations as well as give information on grain size distribution and statistics. A new ASTM…

A recent revision to ASTM International standard E384 , Test Method for Knoop and Vickers Hardness of Materials, expands the range of its coverage. The standard is under the jurisdiction of Subcommittee E04.05 on Microindentation Hardness Testing, part of ASTM International Committee E04 on Metallography. The revision incorporates ASTM E92 , Test Method for Vickers Hardness of Metallic Materials…

High-speed machine tool spindles and the high-pressure turbopumps that move liquid hydrogen in the space shuttle are just two examples of the uses for hybrid roller bearings. ASTM Subcommittee F34.01 on Rolling Element has now developed a standard for hybrid roller bearings, ASTM F2730/F2730M , Specification for Silicon Nitride Cylindrical Bearing Rollers. Subcommittee F34.01 is under the…

ASTM International Committee F34 on Rolling Element Bearings is seeking participation in a new activity on measuring the cleanliness and wetability of bearing components. Because aerospace customers currently use many different methods of testing ball bearings, the goal of the activity is to work toward a consistent method for measuring cleanliness and wetability, as well as to analyze the…
