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…

Dried blood represents the greatest challenge to cleaning surgical instruments. To meet this challenge, ASTM International Committee D12 on Soaps and Other Detergents has developed a new standard, D 7225 , Guide for Blood Cleaning Efficiency of Detergents and Washer-Disinfectors. The new guide is under the jurisdiction of Subcommittee D12.16 on Hard Surface Cleaning. Water-soluble components of…

ASTM International Committee C09 on Concrete and Concrete Aggregates has recently approved two new standards, C 1611, Test Method for Slump Flow of Self-Consolidating Concrete, and C 1622, Specification for Cold-Weather Admixture Systems. Descriptions of both new standards follow. , C 1611 Test Method for Slump Flow of Self-Consolidating Concrete, The concrete industry has been using self-consolidating concrete for the past several years. A new ASTM International standard developed by Committee C09 on Concrete and Concrete Aggregates, C 1611, Test Method for Slump Flow of Self-Consolidating Concrete, will allow users to measure the consistency of self-consolidating concrete for the first time. "Because of its high fluidity, the…, C 1622 Specification for Cold-Weather Admixture Systems, Using concrete during construction in cold weather is difficult since concrete can freeze before it hardens. However, a new ASTM standard, which is the result of a project to prove that antifreeze technology for concrete is feasible, will allow for greater use of concrete during construction in cold weather. ASTM Committee C09 on Concrete and Concrete Aggregates has approved the new standard…
