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 help determine impurities in monoethylene glycol (MEG). ASTM’s committee on aromatic, industrial, specialty, and related chemicals ( D16 ) developed the standard, which will soon be published as D8311. MEG is used predominantly as a raw material in the production of polyester fibers, but it is also commonly used as a heat transfer fluid and a component in…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Melissa Marcinowski, tel +1.610.832.9626; mmarcinowski@astm.org Release #11024 ###

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 test method (D8266) will help analyze impurities of a certain compound (bisphenol A) used in polycarbonate and epoxy resin, helping support the manufacturing and trade of many plastic products. Impurities in bisphenol A can slow down polymerization and result in impurities of the final product, according to Huang Yu, a junior engineer at Sinopec. She says that the test helps determine trace…
