ISA-100.11a-2011, "Wireless Systems for Industrial Automation: Process Control and Related Applications," has received approval from all 21 participating National Committees of the International Electrotechnical Commission (IEC) that voted on the IEC version in a recently completed Committee Draft for Vote (CDV) stage.
The CDV stage is the final stage in the IEC process in which technical comments may be considered. The standard, expected to be issued in early 2014 for a final IEC approval stage in which no technical comments may be submitted, will carry the designation IEC 62734 upon publication. This follows previous approval of ISA-100.11a as an ISA and American National Standard. The latter confirmed that ISA’s open consensus standards development procedures as accredited by the American National Standards Institute (ANSI), which require participation not only of suppliers but of all key interest categories, were followed properly in developing ISA-100.11a.
Notably, ISA’s ANSI-accredited procedures provide for direct participation and voting by experts from end-user companies, ensuring consideration of the views and requirements of those who will actually be deploying wireless systems in real-world industrial applications. That end-user input is now evident in the growing worldwide application of ISA-100.11a technology in processes including oil and gas, liquefied natural gas (LNG), refining, petrochemicals, chemicals, power, biopharmaceuticals, thermal processing and water treatment.
In a presentation at the 2013 ARC Forum, for example, C. B. Chakradhaar of RasGas described the highly cost-effective application of ISA-100.11a-compliant wireless temperature transmitters to monitor a critical component in LNG production. Based on that success, he indicated, ISA-100.11a has been adopted as a plant-wide standard for all future wireless applications.
