A new ASTM International standard covers a special grade of industrial woven wire cloth called filter cloth for general filtration, including the separation of solids from fluids. ASTM E2814 , Guide for Industrial Woven Wire Filter Cloth, was developed by Subcommittee E29.01 on Sieves, Sieving Methods and Screening Media , part of ASTM International Committee E29 on Particle and Spray…, ASTM Committee E29 Next Meeting:, Oct. 31-Nov. 1, 2011, October Committee Week, Tampa, Fla., Technical Contact:, Ken Beyer, Unique Wire Weaving Co., Hillside, N.J., Phone: 908-688-4600; ken@uniquewire.com, ASTM Staff Contact:, Christine Sierk, Phone: 610-832-9728; csierk@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8934

Invented in the early 1990s, the tomographic gamma scanner is used in the nondestructive assay of radioactive waste contained in drums or cans. In the last 10 years, TGS technology has been industrialized, with systems operating in South Korea, the United States and Europe. A new ASTM International test provides users with a means of streamlining TGS procedures and practices, and it will be…

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…

In response to requests from fuel producers around the world, ASTM International Committee C26 on Nuclear Fuel Cycle has developed a standard for using the total evaporation method to determine uranium or plutonium composition. The new standard, C 1672 , Test Method for Determination of Uranium or Plutonium Isotopic Composition or Concentration by the Total Evaporation Method Using a Thermal…

Neutron absorbers have been used for criticality control in spent nuclear fuel pools and in spent fuel transportation casks for decades. However, since the late 1980s, as spent fuel storage pools have been filled, utilities have transferred spent fuel into dry dual-purpose (storage/transportation) canisters. The neutron absorbers used in dual-purpose canisters are subjected to different operating…
