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

A new ASTM International practice provides a standard for preparing a mixture of cement paste that will simulate the shearing experienced by the cement paste in concrete. The new standard, ASTM C1738 , Practice for High-Shear Mixing of Hydraulic Cement Pastes, was developed by Subcommittee C01.22 on Workability , part of ASTM International Committee C01 on Cement . According to Chiara Ferraris,…

ASTM grain size is a property written into many specifications for metals, with finer grain sizes generally indicating better mechanical properties, such as formability. While measuring certain materials for such properties can be difficult, electron backscatter diffraction can provide precise determinations as well as give information on grain size distribution and statistics. A new ASTM…

A recent revision to ASTM International standard E384 , Test Method for Knoop and Vickers Hardness of Materials, expands the range of its coverage. The standard is under the jurisdiction of Subcommittee E04.05 on Microindentation Hardness Testing, part of ASTM International Committee E04 on Metallography. The revision incorporates ASTM E92 , Test Method for Vickers Hardness of Metallic Materials…

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…

A recently approved revision to ASTM International standard C 150 , Specification for Portland Cement, includes three significant technical changes to the document. The changes are part of a joint effort between ASTM and the American Association of State and Highway and Transportation Officials to harmonize C 150 with AASHTO’s standard, M 85, Specification for Portland Cement. C 150 is under the…

A proposed new standard currently being developed by ASTM International Committee F01 on Electronics will prove to be useful to the tantalum sputtering target industry. The proposed standard, WK9490, Test Method for Reporting Crystallographic Orientation of Sputtering Target Materials, is under the jurisdiction of Subcommittee F01.17 on Sputter Metallization. "The tantalum sputtering target…
