ISA12.21, Optically radiating equipment and fiber optics in hazardous locations
The subcommittee shall survey, monitor, and participate in the development of national and international standards, practices, and codes addressing optically radiating equipment and fiber optics in hazardous (classified) locations.
Provide support to ISA in the areas of optically radiating equipment and fiber optics in hazardous (classified) locations.
To develop, publish and maintain standards and practices related to optically radiating equipment and fiber optics in hazardous (classified) locations.
To enhance the protection concepts of such optically radiating equipment and fiber optics, and ISA's continued leadership in this area.
To promote current technology for the proper installation, use, and maintenance of optically radiating equipment and fiber optics to enhance safety in hazardous (classified) locations.
To provide technical support to industry in the areas of optically radiating equipment and fiber optics in hazardous (classified) locations.
The ISA12.21 subcommittee met on Thursday, 28 February 2013 in conjunction with the Spring 2013 ISA meetings. Updates to the current membership roster for submission to ISA12 were identified, including the addition of the following new Information members: Rich Holub (DuPont Engineering), Laji Isac (Weatherford), and Arthur Shvartsman (Intertek). This membership update is to be approved by ISA12.
Primary focus during this meeting was on draft edition 1.1 revisions to ISA-60079-28. Balloting on these draft edition 1.1 revisions closed successfully with only one negative. All committee / subcommittee comments were addressed, with additional revisions resulting from these comment resolutions. As all these additional revisions were editorial in nature, this draft edition 1.1 can be progressed towards publication. USNC comments on a draft 2nd edition of IEC 60079-28 (now at CD stage) were also discussed in preparation for the upcoming MT 60079-28 meeting scheduled for London (UK) in conjunction with the Spring 2013 IEC/TC 31 meetings.
Regarding ANSI/ISA-TR12.21.01-2004, instead of beginning an effort to develop it into an ANSI standard for Division equipment certification, a decision was made to retain this document as an ANSI test report containing the foundational technical material on which US and IEC optical radiation requirements are based. ISA12.21 will monitor the progress of a joint IEEE/IEC trace heating standard that is intended to contain both Zone and Division equipment certification requirements as a potential model for how the scope of ISA-60079-28 could be expanded in the future to address both Zone and Division equipment certification requirements.
Finally, discussions ensued regarding opportunities to educate US industry on the risk of explosion from optical radiation. A paper abstract is under consideration for presentation at the 2013 IEEE/PCIC technical conference in Chicago. If this abstract presentation is accepted, the formal paper presentation would occur at the 2014 IEEE/PCIC technical conference in San Francisco.
The next meeting of ISA12.21 will be in conjunction with the Fall 2013 ISA12 meetings.
