ASTM International’s thermal measurements committee ( E37 ) is developing a proposed standard that describes a reliable technique for investigating the thermal transport properties of materials. The proposed standard ( WK49591 ) will help to provide information on thermal conductivity, thermal diffusivity, and volumetric heat capacity. According to ASTM International member Artem Trofimov,…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Steve Mawn, tel +1.610.832.9726; smawn@astm.org Release #11705 ###

ASTM International’s wear and erosion committee ( G02 ) has released a new standard that provides a test method for measuring friction and adhesive wear properties of lubricated and nonlubricated materials using the twist compression test (TCT). The new standard (soon to be published as G223) can be used to “rank combinations of surfaces in their resistance to adhesive wear. This can be useful…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Jennifer Tursi HER , tel +1.610.832.9653; jtursi@astm.org Release #11697 ###

A new ASTM International standard will provide a specification for low density poly vinylidene fluoride (PVDF) based materials intended for use in wire and cable jacketing. ASTM’s committee on electrical and electronic insulating materials (D09) developed the standard, which will be soon published as D8318. Low density PVDF cable jacketing is a new product that has the potential to offer…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Alyson Fick, tel +610.832.9710; afick@astm.org Release #11058 ###

Rotational viscometry is an easily used tool for determining the viscosity of fluids, including paints, petroleum products and polymer solutions. While standards often make use of rotational viscometry, a procedure for calibrating or validating the measurement is not always part of the standard, which could lead to results that differ from one laboratory to another. A proposed user viscosity…, ASTM Committee E37 Next Meeting:, March 14, 2014, ASTM International Headquarters, West Conshohocken, Pa., Technical Contact:, Roger Blaine, Corvallis, Ore., Phone: 302-559-6827; roger.l.blaine@gmail.com, ASTM Staff Contact:, Tom O'Toole, Phone: 610-832-9739; totoole@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9493

Piston ring/liner interface can contribute as much as half the total friction loss in internal combustion engines, with the resulting wear leading to reduced energy efficiency and raised emissions. A new ASTM International standard provides a method to more accurately measure small amounts of wear on curved piston ring segments and their counterfaces after lubricated bench-scale testing. “Coupled…
