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

Keeping birds away from potentially fatal encounters with building exteriors is the purpose of a proposed new ASTM International standard, ASTM WK47853 , Test Method for Bird Collision Deterrence Material Threat Factor. It is possible that as many as a billion birds are killed every year after colliding with glass on buildings, including many single-family homes — and this is in the United States…, ASTM Committee C14 Next Meeting:, April 14, 2015, Moorestown, N.J., Technical Contact:, Stefan Knust, Ennead Architects, New York, New York, tel +1.212.807.7171; sknust@ennead.com, ASTM Staff Contact:, Thomas O’Toole, tel +1.610.832.9739; totoole@astm.org, ASTM PR Contact:, Barbara Schindler, tel +1.610.832.9603; bschindl@astm.org Release #9767

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

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…

A new ASTM International standard describes a variety of methods that can be used to determine the index of refraction and dispersion of glass. The standard, C 1648 , Guide for Choosing a Method for Determining the Index of Refraction and Dispersion of Glass, will be useful to manufacturers of glass and glass products as well as designers of products in which glass is a critical component. C 1648…
