Flow characteristics of fine metal powders are important in filling dies for pressing of powder metallurgy compacts, which are later sintered and sometimes machined into finished parts. The flow rate, as measured by a new ASTM standard, determines the flow necessary for a precise quantity of powder to be introduced into the die. The new standard, B964 , Test Methods for Flow Rate of Metal Powders…

Two recently approved ASTM International standards provide user-friendly tests for properties of sintered metallurgy products. The new standards, developed by Subcommittee B09.04 on Bearings, are ASTM B962 , Test Methods for Density of Compacted or Sintered Power Metallurgy (PM) Products Using Archimedes’ Principle, and ASTM B963 , Test Methods for Oil Content, Oil-Impregnation Efficiency and…

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…

ASTM International Committee C26 on Nuclear Fuel Cycle has recently published a new standard and has begun the development of a proposed new standard. Subcommittee C26.14 on Remote Systems is responsible for the newly approved standard, C 1661 , Guide for Viewing Systems for Remotely Operated Facilities, while Subcommittee C26.02 on Fuel and Fertile Material Specifications is currently at work on…, C 1661, Guide for Viewing Systems for Remotely Operated Facilities, A new ASTM International standard establishes minimum requirements for viewing systems for remotely operated facilities, including hot cells, used for the processing and handling of nuclear and radioactive materials. The standard, C 1661 , Guide for Viewing Systems for Remotely Operated Facilities, was developed by Subcommittee C26.14 on Remote Systems, which is part of ASTM International…, WK14330, Nuclear Fuel Pellet Physical Integrity Limits: Chips, Cracks, Defects, The quality of fuel pellets is currently an important topic being studied throughout the nuclear industry, with study groups such as the Electric Power Research Institute and Institute of Nuclear Power Operations examining the effect of pellet quality on the performance of nuclear fuel. ASTM International Committee C26 on Nuclear Fuel Cycle is addressing the topic of fuel pellets with a proposed…

A proposed new standard being developed by ASTM International Committee B09 on Metal Powders and Metal Powder Products offers a solution to the challenge of handling and characterizing very fine powders. Subcommittee B09.02 on Base Metal Powders is developing the proposed standard, WK13023 , Test Method for Determination of Tap Density of Metallic Powders by a Constant Volume Measuring Method. …

Conventionally processed powder metallurgy materials often exhibit open microporosity at the surface. While it is a natural part of the process, this microporosity can affect the measurement of surface finishes. To cover this and other issues that arise from measuring the surface finish of powder metallurgy, ASTM International Committee B09 on Metal Powders and Metal Powder Products has developed…

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…
