A proposed new ASTM International standard will assist users of cyanide analysis methods who want to work in compliance with the International Cyanide Management Code. The Code covers the proper handling of cyanide from production, transportation to processing sites and design of cyanide facilities, including detoxification, storage and release of excess cyanide processing waters. ASTM WK27288 ,…

In an action effective on Nov. 10, 2009, 15 methods contained in 10 ASTM standards are among 25 analytical methods that the U.S. Environmental Protection Agency has approved for determining contaminant concentrations in samples collected under the Safe Drinking Water Act. The methods are under the jurisdiction of Subcommittee D19.05 on Inorganic Constituents in Water, part of ASTM Committee D19…, ASTM Committee D19 Next Meeting:, Jan. 17-21, Cocoa Beach, Fla., ASTM Staff Contact:, Brynn Murphy , Phone: 610-832-9640; bmurphy@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #84 52/Jan2010

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…

Honeycomb ceramics, porous with linear hollow channels, are being used worldwide in automotive catalytic converters and as diesel particulate filters for trucks. Flexural testing of this type of ceramics is addressed in a new ASTM International standard, ASTM C1674 , Test Method for Flexural Strength of Advanced Ceramics with Engineered Porosity (Honeycomb Cellular Channels) at Ambient…

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…

Ceramic and glass companies, as well as universities and government laboratories, will be the primary users of a new ASTM standard that allows for the flexural strength determination of components made in a round shape or after finish machining with minimal waste. The standard, ASTM C1684 , Test Method for Flexural Strength of Advanced Ceramics at Ambient Temperature-Cylindrical Rod Strength, was…

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…
