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 test method related to unfixed chrome concentrations in Wet Blue. The standard, soon to be published as D8451, was developed by ASTM’s committee on leather ( D31 ). According to ASTM International member Okey Abara, Wet Blue is an intermediate product used for processing natural hides. It is produced when a tanning agent chemically binds to the…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, David Lee, tel +1.610.832.9681; dlee@astm.org Release #11463 ###, ,

ASTM International’s committee on leather ( D31 ) is developing a proposed standard that will help to assess the effect of various soling agents on leather. The primary aim of the proposed standard ( WK74216 ) is to assess the degree of resistance and cleanability of a leather surface after it has been in contact with potential staining agents. Among the effects covered in the standard are…, Media Inquiries: , Dan Bergels, tel +1.610.832.9602; dbergels@astm.org , Committee Contact:, David Lee, tel +1.610.832.9681; dlee@astm.org Release #11097 ###

A new ASTM International standard will be used to determine the alkalinity of oils used to soften the stuffing of leather products. ASTM’s leather committee (D31) developed the standard, which will soon be published as D8284. Total alkalinity is a chemical measurement of water’s ability to resist change in pH, also known as water buffering capacity. According to ASTM International member…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact: , David Lee, tel +1.610.832.9681; dlee@astm.org Release #10879

A new standard developed by ASTM International’s leather committee (D31) provides test methods to estimate its longevity. This new test method (soon to be published as D8137) provides a way to evaluate longevity considering everyday atmospheric conditions like smog and corrosive gases. ASTM International member Kadir Donmez, associate director of the leather research laboratory at the…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, David Lee, tel +1.610.832.9681; dlee@astm.org Release #10582

If a leather article such as a shoe or a glove were left next to a heater for an extended period of time, would the finish remain soft and flexible or would it change color and develop cracks within the leather finish? A new ASTM International standard will help to answer that question, giving manufacturers a clear method to predict and prevent such problems. ASTM D7912 , Test Method for…, Technical Contact:, Kadir Donmez, Leather Research Laboratory, University of Cincinnati, Cincinnati, Ohio, Phone: 513-242-6300; donmezk@uc.edu, ASTM Staff Contact:, Ashley Wiand, Phone: 610-832-9551; awiand@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9623

A new ASTM International standard, adopted from an American Concrete Institute test method, will be used to help ensure the safety of construction projects. ASTM C1741 , Test Method for Bleed Stability of Cementitious Post-Tensioning Tendon Grout, is under the jurisdiction of Subcommittee C09.41 on Hydraulic Cement Grouts , part of ASTM International Committee C09 on Concrete and Concrete…

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…

Wet blue and wet white are intermediate products used by tanneries that process natural hides and skins into leather. Natural fats and oils need to be largely removed from wet blue and wet white for leather processing to be done properly, but no standard had previously existed to evaluate the effectiveness of such removal. ASTM International Committee D31 on Leather has now developed such a…

ASTM Committee G02 on Wear and Erosion is including a field trip in the plans for its Dec. 8-9 meeting in Jacksonville, Fla. Committee members will be visiting the Tribology Laboratory in the mechanical engineering department at the University of Florida in Gainesville. The Tribology Laboratory is actively involved in a wide variety of tribological research and tribology education projects. The…
