ISA, the Instrumentation, Systems, and Automation Society , is updating several of its standards on electrical equipment for hazardous locations, and has also released a new calibration guide.
Three of the eight IEC 60079 Series-based ISA/UL co-published standards on electrical equipment for hazardous locations are being revised, based on new editions of IEC standards. These and other ISA 60079 Series standards help ease global trade of U.S.-manufactured electrical equipment for use in explosive atmospheres.
One—ISA 60079-0 (12.00.01), “Electrical Apparatus for Use in Class I, Zones 0, 1, & 2 Hazardous (classified) Locations: General Requirements”—is scheduled for publication this month, following its submission for a 10-day default ISA Standards & Practices Board ballot and for ANSI approval. Two others under revision are scheduled for publication later this year after ballot completion and ANSI approval. The eight standards will be re-designated with an IEC number following “ISA” and the ISA standards committee-related number in parentheses to avoid confusion and more closely align ISA and IEC standards.

ISA also recently released Calibration: A Technician’s Guide . Billed as a comprehensive review of calibration by industry expert Mike Cable, the guide provides a foundation for understanding principles and applications of the most frequently performed tasks of a technician. Topics addressed include terminology; bench vs. field calibration; loop vs. individual instrument calibration; and specific calibration techniques for temperature, pressure, level, flow, final control, and analytical instrumentation.
