Analysts in laboratories that use regression-based methods to determine uncertainty in data and customers that request such measurements will be the primary users of a new standard recently approved by ASTM International Committee D19 on Water. ASTM D7366 , Practice for Estimation of Measurement Uncertainty for Data from Regression-Based Methods was developed by Subcommittee D19.02 on Quality…

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…

Cyanide is routinely analyzed in water samples, often to demonstrate regulatory compliance; however, improper sample collection or pretreatment can result in significant positive or negative bias potentially resulting in unnecessary permit violations or undetected cyanide releases into the environment. Because of the importance and timeliness of these issues, ASTM Subcommittee D19.06 on Methods…

While nearly all of the instrumentation employed in the field to measure radioactive materials or radiation exposure rates used to be in the hands of state radiological control agencies or federal government national response organizations, this is no longer the case. Now, law enforcement personnel, first responders and other professionals have radiation detection instruments, though they may not…

ASTM International Committee E57 Will Meet Important Industry Need for Consensus Standards, ASTM International, one of the largest voluntary standards development organizations (SDO) in the world, has announced the formation of ASTM Committee E57 on 3D Imaging Systems. The new standards initiative was driven by the cooperative efforts of the National Institute of Standards and Technology (NIST) and stakeholders within the 3D imaging systems sector. Committee E57 will focus on the…, Powerful Tools for Measurement and Information Capture, 3D imaging systems are used to rapidly capture three-dimensional information of a scene or object. This information is often provided in the form of “point clouds” (grouping of points) with associated color and intensity data. Usage of 3D imaging systems has steadily increased during the past 10 years as the devices have become important measuring tools in industrial sectors such as construction…, Dynamic, Growing Technology in Need of Consensus Standards, 3D imaging technology has been in existence for several decades. Current systems include laser scanners, 3D optical scanners, 3D range cameras, and 3D flash laser radars (LADARs). Although these systems have become more established during the last decade, there are presently no standards for evaluating the performance of 3D imaging systems or the related end projects derived from the data they…, ASTM International: Meeting the Call for a Comprehensive Standards Program, Following a NIST workshop of stakeholders from the 3D imaging systems sector held in March, ASTM International was chosen in a competitive bid process to be home of the new standards initiative. With a proven consensus process and state-of-the-art standards development infrastructure, ASTM is well suited to meet the 3D imaging industry’s need for comprehensive standards. ASTM Committee E57 will…

After a 35-year-absence, the natural cement industry is being revived and, along with it, a long-withdrawn ASTM International standard. Until it closed in 1970, the Century Cement Company in Rosendale, N.Y. was the last company to manufacture natural cement. Up to that point, Rosendale had been the center of the industry, the source of more than half of all natural cement produced in the U.S.…

A new test method developed by ASTM International Committee C01 on Cement provides information about the behavior of cement that can be used in the process of selecting cementing materials for specific applications. The standard, C 1608, Test Method for Chemical Shrinkage of Hydraulic Cement Pastes, is under the jurisdiction of Subcommittee C01.31 on Volume Change. Test Method C 1608 was…
