New Advanced Ceramics Standards from ASTM Cover Fracture Mirror Size Analysis, Tensile Strength DataSubcommittee C28.01 on Mechanical Properties and Performance, part of ASTM International Committee C28 on Advanced Ceramics, has recently approved two new standards, ASTM C1678 , Practice for Fractographic Analysis of Fracture Mirror Sizes in Ceramics and Glasses, and ASTM C1683 , Practice for Size Scaling of Tensile Strengths Using Weibull Statistics for Advanced Ceramics., ASTM C1678 —Bringing Consistency to Fracture Mirror Size Analysis, Fracture mirror size analysis is a powerful quantitative tool for the interpretation of broken ceramic and glass articles. While this type of analysis can be used to determine the stress in a part at the instant of fracture, inspection and interpretation procedures have often varied, resulting in uncertainty in stress estimates. ASTM C1678, Practice for Fractographic Analysis of Fracture Mirror…, ASTM C1683 —Scaling Strength Values, ASTM C1683, Practice for Size Scaling of Tensile Strength Using Weibull Statistics for Advanced Ceramics, provides methodology to convert fracture strength parameters estimated from data obtained with one test geometry to strength parameters representing other test geometries. Stephen Duffy, chair of civil engineering, Cleveland State University, and C28 member, says that companies producing…

One of the goals of Subcommittee E54.05 on Building and Infrastructure Protection is to provide guidance for the design of doors, windows and other opening protectives that are part of the exterior security envelopes of buildings. As one path to achieve that goal, the subcommittee is currently developing a proposed new standard, WK14650 , Test Methods for Forced Entry and Ballistics Resistant (…

A proposed new ASTM International standard will help emergency responders develop succinct, usable emergency response guidance in the event of a radiological event, which may include an intentional release or an attack involving a radiological dispersal device (also known as a “dirty bomb”). The proposed standard, WK7020 , Guide for the Development of a Radiological Emergency Response Playbook,…

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…

ASTM International, one of the largest voluntary standards development organizations in the world, announced the approval and availability of a new standard for collecting, packaging, and transporting visible powder samples suspected of being biological agents. ASTM E 2458 ,, Standard Practices for Bulk Sample Collection and Swab Sample Collection of Visible Powders Suspected of Being Biological Agents from Nonporous Surfaces, is the first standard to address the subject. E 2458 incorporates reference guidance to comply with appropriate federal regulations regarding biosafety and biosecurity. The standard is applicable to nonporous surfaces only., Cooperative Interagency and Stakeholder Effort, The development of a sample collection standard was initiated by the U.S. Department of Homeland Security (DHS) in order to address the problems associated with haphazard sample collection and screening. DHS assigned the National Institute of Standards and Technology (NIST) to coordinate and lead a task group whose charge was to develop a standard protocol for the collection of powders that are…, ASTM Committee E54 on Homeland Security, Currently there are over 500 stakeholders in Committee E 54 on Homeland Security, representing diverse groups including first responders, manufacturers, suppliers, trade and professional associations, and federal, state and local government. The committee was first organized in 2003. E 2458 is the third standard issued by Committee E54 on Homeland Security, and the first standard of Subcommittee…, Two-Step Procedure, E 2458 is a two-step procedure that is performed after an initial risk assessment is conducted and a visible powder is deemed a credible biological threat. The first step of the procedure, or Method A, covers the bulk collection and packaging of the suspicious visible powders from solid nonporous surfaces. Bulk samples are collected and transported in a manner that permits public health and…, Sample Collection Procedure Proven to Work, A study was conducted in March 2006 to validate the reliability of the sampling procedure at the U.S. Army Dugway Proving Ground. The study demonstrated that the sampling procedure can be used by trained Emergency Responders in simulated emergency conditions to consistently recover samples. The study also proved that sufficient number of Bacillus anthracis spores can be detected by Emergency…, after, all bulk samples have been collected. The evaluation study was designed to determine the recovery efficacy on seven environmental surface types that included stainless steel, food-grade painted wood, rubber, tile, concrete, finished wood, and plastic. The study involved six teams that included four National Guard Civil Support Teams (CST), the Navy’s Chemical Biological Incidence Response Force (…, Contacts, ASTM standards are available from Customer Service (610-832-9585); https://www.astm.org/contact/ ) or the ASTM web site store ( www.astm.org ).
