ASTM International has fully redesigned its International Laboratory Directory, the only directory in the world dedicated to helping manufacturers find the right labs to test their products. Independent laboratories throughout the world rely on thousands of standards and test methods, including many developed by ASTM International. By working with these labs, manufacturers can help ensure that…, Contact:, Anna Spektor, tel +1.610.832.9756; aspektor@astm.org, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org Release #10110

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…

Rapid hardening hydraulic cements are used in a variety of applications in which reduced cementitious contents are desired or early service is needed. Included among these applications are paving, construction, stucco, mortar and block. A newly approved ASTM International standard covering these cements, ASTM C1600/C1600M , Specification for Rapid Hardening Hydraulic Cement, has been developed by…, Type URH, —ultra rapid hardening, for use where ultra high early strength is desired;, Type VRH, —very rapid hardening, for use where very high early strength is desired;, Type MRH, —medium rapid hardening, for use where mid-range rapid hardening, high early strength is desired; and, Type GRH, —general rapid hardening, for use when the higher strength properties of Type VRH or a Type MRH cement is not required. “ASTM C1600 lists minimum requirements for compressive strength, setting time, shrinkage and soundness (autoclave expansion),” says Hicks. “Optional specifications for sulfate expansion, alkali silicate reactions with aggregates, heat of hydration and expansion in water are also…

Since 1998, when ASTM International Committee F05 on Business Imaging Products first approved standard F 1856 , Practice for Determining Toner Usage for Printer Cartridges, there has been a rapid increase in the use of color in office printing. In order to address this important change, Subcommittee F05.04 on Electrostatic Imaging Products has developed F 2632 , Practice for Determining the Toner…

The ability to determine the number of pages an ink jet printer cartridge will print in its lifetime is essential for anyone who manufactures or remanufactures them. A new ASTM International standard, F 2555 , Practice for Determining Page Yield of Ink Jet Printer Cartridges — Continuous Printing Method, has been developed to aid in this endeavor. Practice F 2555 is under the jurisdiction of…
