Keeping pipes properly connected is clearly an important aspect of any sewer maintenance system. A new ASTM International standard, F 2561, Practice for Rehabilitation of a Sewer Service Lateral and Its Connection to the Main Using a One-Piece Main and Lateral Cured-in-Place Liner, has been developed that makes the process of keeping sewer pipelines connected more effective.
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.
X-ray fluorescence spectrometry is used often to determine a wide range of elements in alloys. The technique provides rapid, accurate, and precise multi-element analysis that enables efficient melt process control. It is also widely used for certification and over-check analysis of product.
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.
A new ASTM International standard provides information and criteria for estimating the thickness of oil on water using only visual clues. The standard, F 2534, Guide for Visually Estimating Oil Spill Thickness on Water, was developed by Subcommittee F20.16 on Surveillance and Tracking to provide a consistent means of visual oil spill thickness detection.
Selecting and using monitoring methods to protect water systems is the focus of a new standards development effort. Subcommittee E47.05 on Risk Assessment, Communication and Management has begun WK11621, New Standard Guide for Selecting and Using Ecological Sentinels for National Security Monitoring, to accomplish this goal.
ASTM International Committee F40 on Declarable Substances in Materials has recently approved their first standard, F 2576, Terminology Relating to Declarable Substances in Materials. The standard, which will serve as the committee’s lexicon of terms, abbreviations and units, is under the jurisdiction of Subcommittee F40.91 on Terminology.
The rapid growth and variety of rides being developed within the water park industry has created a need for new standards to regulate the design and installation of water slides. While individual states within the United States had created rules and guidelines for water slides, these often varied greatly from each other.
Anyone who has ever lost time searching for a set of keys that simply are not where they’re supposed to be will appreciate the larger-scale, though similar concept behind E 2499, Standard Practice for Classification of Equipment Physical Location Information, a new standard developed by ASTM International Committee E 53 on Property Management Systems.
A new ASTM International publication, STP 1482, Contaminated Sediments: Evaluation and Remediation Techniques, contains 38 peer-reviewed papers on the latest advances in the fields of environmental science and underwater engineering related to sediments.
