ASTM International is seeking stakeholders in the transportation gasket industry to help one of its task groups develop property standards regarding gasket materials and analysis.
ASTM Task Group F03.95.03 on Gasket Material Characterization for Finite Element Analysis is working to establish property standards enabling users of finite element analysis to insert required gasket properties in their equations and conduct credible analysis, according to Peter Petrunich, technical director of the Fluid Sealing Association and the task group chairman.
``The auto industry is the driving force behind this standard development for gaskets,'' Petrunich said. ``Standard procedures for certain properties don't exist, and there are some holes in some of the current standards.''
Needs for the industrial sector also will be investigated, he said.
The initial effort of the task group is to put together a matrix of information-including needed properties, materials used and software employed-so it can understand what needs must be addressed in forming the property standards, Petrunich said.
The group is not focusing on particular types of gaskets or materials, but will better specify the standards for one group of materials if necessary as the process goes along.
Finite analysis issues for soft gasket material, molded rubber, elastomers and other materials will be examined, he said.
ASTM, one of the largest standard development organizations globally, wants to involve a variety of representatives from the worldwide transportation gasket community-particularly from automotive-including engineers, gasket manufacturers, designers, finite element analysis retailers and end users in the process.
Petrunich said new standards will make life easier on gasket manufacturers and users. ``It allows for better definition of application and performance needs and therefore better definition of which products meet performance requirements,'' he said.
The ASTM task group will complement its efforts with the Society of Automotive Engineers. Task group members will meet with SAE representatives during the SAE's annual World Congress in Detroit in early March, Petrunich said.
``We want to get as much input as possible, including from colleagues in Europe and Asia,'' he said. ``It will make the end result a stronger, more effective document.''
There is no current timeline for collecting information or for moving the standard development process along to the subcommittee or committee levels, Petrunich said. The task group is part of ASTM Committee F03 on Gaskets and ASTM Planning Subcommittee F03.95.
