Rotational viscometry is an easily used tool for determining the viscosity of fluids, including paints, petroleum products and polymer solutions. While standards often make use of rotational viscometry, a procedure for calibrating or validating the measurement is not always part of the standard, which could lead to results that differ from one laboratory to another. A proposed user viscosity…, ASTM Committee E37 Next Meeting:, March 14, 2014, ASTM International Headquarters, West Conshohocken, Pa., Technical Contact:, Roger Blaine, Corvallis, Ore., Phone: 302-559-6827; roger.l.blaine@gmail.com, ASTM Staff Contact:, Tom O'Toole, Phone: 610-832-9739; totoole@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9493

Three dimensional image system technology is now used in a wide variety of industries, including construction, mapping, manufacturing, mining and forensics. For all of these industries, safe usage of 3D imaging equipment is a top priority. However, until the approval of a new ASTM International standard, no safety guidelines specifically oriented toward 3D image system technology existed. The…

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…
