Subcommittee A05.13 on Structural Shapes and Hardware Specifications is currently working on proposed new standards that would be used by engineers and architects who design with steel fabrications. These proposed standards will be used to evaluate the costs of steel construction over the lifetime of a project and to compare different corrosion protection systems on their impact to this lifetime…

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…

Arc protective blankets are used in many electrical applications to protect workers who are stationed near energized electrical parts. While these blankets have been used for years, there have been no testing criteria for their evaluation. A new ASTM International standard will be used to determine the effectiveness of arc protective blankets in suppressing the combined effect of an arc flash and…

Galvanized steel products are manufactured and used throughout the world. A new ASTM International standard, A1057/A1057M , Specification for Steel, Structural Tubing, Cold Formed, Welded, Carbon, Zinc-Coated (Galvanized) by the Hot-Dip Process, addresses the galvanizing process as it is used across a variety of industries, including construction, automotive and transportation. The new standard…

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…
