Data produced from the use of a proposed new ASTM International standard will be employed in the design of new, more efficient aircraft engines as well as for piping, steam and gas turbines used in power generation. The proposed new standard, WK21984 , Test Method for Creep-Fatigue Crack Growth Rate Testing, is being developed by Subcommittee E08.06 on Crack Growth Behavior, part of ASTM…

The use of rolling devices can provide a means to evaluate the adhesion of weather seals, for quality control in new installations, general evaluation of existing installations, and the investigation of water and air leakage through building enclosures. In order to better facilitate the use of rolling devices, ASTM International Committee C24 on Building Seals and Sealants is developing a…

Although alkali resistant glass fibers have been commercially available for more than 30 years, there has not been an official standard that clearly defines what is required to make glass fibers resistant to alkali attack without the need for protective coatings. ASTM International Committee C27 on Precast Concrete Products has recently developed such a standard, C 1666/C 1666M , Specification…

ASTM International Committee F41 on Unmanned Undersea Vehicle Systems invites all interested parties to participate in a new task group, F41.90.01 on Unmanned Surface Vehicles. With the addition of this new task group, the name of Committee F41 will be changed to Unmanned Maritime Systems. Task Group F41.90.01 is seeking new members with expertise in unmanned surface vehicles to complement the…

ASTM International Committee C24 on Building Seals and Sealants invites interested parties to participate in the development of a proposed new standard that will use photographs to illustrate various types of sealant failures. WK11731 , Guide for Diagnosing Sealant Failure by Comparison to Reference Photographs, is under the jurisdiction of Subcommittee C24.10 on Specifications, Guides and…

Ineffective removal of grease from restaurants poses a variety of serious environmental problems. Large quantities of grease in public sanitary sewer systems can cause stoppages of piping networks and create costly and time-consuming problems at treatment plants. Sewer backups resulting from grease can also create health hazards when raw sewage backs up into homes or businesses. While grease…

Verifying the results of application software used to calculate the mechanical properties of materials is the subject of a new standard developed by ASTM International Committee E08 on Fatigue and Fracture. The new standard, E 2443, Guide for Verifying Computer-Generated Test Results Through the Use of Standard Data Sets, is under the jurisdiction of Subcommittee E08.03 on Advanced Apparatus and…

Many structures, such as aircraft or other lightweight vehicles, are made from thin-ductile structural materials that exhibit low crack-front constraint, which allows for extensive plastic yielding of the material around a crack front. However, many current standards, such as E 399, Test Method for Linear-Elastic Plane-Strain Fracture Toughness K Ic of Metallic Materials, or E 1820, Test Method…
