The approval, by 81 percent of the voting members of the committee, including 23 of the 24 end-user members, follows two rounds of balloting and refinements to the document to reflect the suggestions received from many interested parties, the ISA said.
“We have passed a major milestone with the Committee vote approving the ISA100.11a draft standard,” said ISA100 co-chair Pat Schweitzer of ExxonMobil Research and Engineering Co., Fairfax, Va. “Once the remaining steps in the process are complete, end-users around the world will have an accredited ANSI/ISA wireless standard which has been developed in an open forum that is the hallmark of ISA standards development.”
Comments received in the latest voting will be reviewed for applicability by Schweitzer and co-chair Wayne Manges, of Oak Ridge National Laboratory, Oak Ridge, Tenn. Other steps remaining in ISA’s consensus-based standards development process include approval by the ISA Standards and Practices Board and ratification by the American National Standards Institute, of which ISA is an accredited member. The co-chairs are hopeful the standard will be published by ISA in August.
