A proposed new ASTM International standard will provide the electrical power industry with a relatively straightforward test for oxidation stability of natural esters. Natural esters, also known as vegetable oils, can be used as an alternative to mineral oil as an insulating liquid in power transformers and other electrical equipment. The proposed standard is ASTM WK21616 , Test Method for…, ASTM Committee D27 Next Meeting:, Nov. 9-11, 2014, November Committee Week, New Orleans, La., Technical Contact:, Kevin J.

No industry standard currently exists that addresses the vacuum sealing requirements of knife-edged flanges for high vacuum applications. Existing international standards focus on interchangeability of the hardware, but do not address the reliability of the seal. ASTM International Committee E42 on Surface Analysis is now working on a proposed standard on the subject, WK21206 , Specification…

ASTM International Committee D27 on Electrical Insulating Liquids and Gases is continuing its work on standards for natural esters with the development of a proposed new standard, WK21616 , Test Method for Oxidation Induction Time of Natural Ester Insulating Fluids by Pressure (PDSC) or Regular Differential Scanning Calorimetry (DSC). The proposed standard was submitted under the jurisdiction of…

A 2002 workshop on galling wear held by ASTM International Committee G02 on Wear and Erosion provided the impetus for the development of a new standard, ASTM G196 , Test Method for Galling Resistance of Material Couples. The new standard is under the jurisdiction of Subcommittee G02.40 on Non-Abrasive Wear. According to Scott Hummel, Ph.D., associate professor, head of the department of…

Plastic pipe and components are used with low pressure oxygen and enriched air for a variety of applications, including medical and healthcare, agriculture (fish farming), welding and fabrication, waste water treatment and others. Despite this widespread use, there are currently no standards that help in the materials selection and design features of these systems. ASTM International Committee…

During the past five years, certain insulating oils have been found to contain corrosive sulfur that can produce copper sulfide deposits as a function of time and temperature in operating equipment. A proposed revision to ASTM standard D 1275, Test Method for Corrosive Sulfur in Electrical Insulating Oils, will provide a means to certify that new or in service oils either contain or do not…

ASTM International Committee G04 on Compatibility and Sensitivity of Materials in Oxygen Enriched Atmospheres originally developed the standard, G 88, Guide for Designing Systems for Oxygen Service, in 1984. Since that time, G 88 has been regarded as one of the leading design guides for oxygen systems throughout all industries that use oxygen. While the original version of the standard contained…

ASTM International will launch a new Proficiency Testing Program (PTP) on Dissolved Gas Analyses (DGA) of In-Service Insulating Fluid in February 2006. The program will be offered to laboratories who need a statistical quality assurance tool that will enable them to improve and maintain a high level of performing ASTM standard D 3612, Test Method for Analysis of Gases Dissolved in Electrical…

ASTM International Committee E42 on Surface Analysis has approved a new standard, E 2382, Guide to Scanner and Tip Related Artifacts in Scanning Tunneling Microscopy and Atomic Force Microscopy. The guide, under the jurisdiction of Subcommittee E42.14 on STM/AFM, was proposed in order to assist new scanning probe microscopy users with more rapid recognition and assessment of artifacts in imaging…
