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

Recent changes in technology are now covered in a significant ASTM International standard used to measure the particle size of metal powders. The standard, ASTM B330 , Test Methods for Estimating Average Particle Size of Metal Powders and Related Compounds Using Air Permeability, is under the jurisdiction of Subcommittee B09.03 on Refractory Metal Powders , part of ASTM International Committee…, ASTM Committee B09 Next Meeting:, April 14-16, 2014, Hollywood, Fla., Technical Contact:, Frank Venskytis, Clayton, N.C., Phone: 919-553-8050; fvastm@embarqmail.com , ASTM Staff Contact:, Katerina Koperna, Phone: 610-832-9728; kkoperna@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9544

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…

Flow characteristics of fine metal powders are important in filling dies for pressing of powder metallurgy compacts, which are later sintered and sometimes machined into finished parts. The flow rate, as measured by a new ASTM standard, determines the flow necessary for a precise quantity of powder to be introduced into the die. The new standard, B964 , Test Methods for Flow Rate of Metal Powders…

Two recently approved ASTM International standards provide user-friendly tests for properties of sintered metallurgy products. The new standards, developed by Subcommittee B09.04 on Bearings, are ASTM B962 , Test Methods for Density of Compacted or Sintered Power Metallurgy (PM) Products Using Archimedes’ Principle, and ASTM B963 , Test Methods for Oil Content, Oil-Impregnation Efficiency and…

A proposed new standard being developed by ASTM International Committee B09 on Metal Powders and Metal Powder Products offers a solution to the challenge of handling and characterizing very fine powders. Subcommittee B09.02 on Base Metal Powders is developing the proposed standard, WK13023 , Test Method for Determination of Tap Density of Metallic Powders by a Constant Volume Measuring Method. …
