Electrical Equipment for Hazardous Locations Standards Updated
Research Triangle Park, NC (11 May 2005) — Three of the eight IEC 60079 series-based ISA/UL co-published standards are being revised based on the new editions of the IEC standards, with one standard, ISA 60079-0 (12.00.01), Electrical Apparatus for Use in Class I, Zones 0, 1, & 2 Hazardous (Classified) Locations: General Requirements, scheduled for publication this month after it has been submitted for a 10-day default ISA Standards & Practices Board ballot and for ANSI approval.
This standard specifies the general requirements for construction, testing and marking of electrical apparatus and Ex components intended for use in Class I, Zone 0, 1, or 2 hazardous (classified) locations as defined by the National Electrical Code, ANSI/NFPA 70.
ISA 60079-1 (12.22.01), Electrical Apparatus for Use in Class I, Zone 1 Hazardous (Classified) Locations: Type of Protection - Flameproof "d" and ISA 60079-18 (12.23.01), Electrical Apparatus for Use in Class I, Zone 1 Hazardous (Classified) Locations: Type of Protection - Encapsulation “m” are also being revised and balloted based on IEC standard updates and are scheduled to be published this year after ballot completion and ANSI approval. The eight ISA co-published standards will be re-designated with the IEC number following “ISA” and the ISA standards committee-related number in parentheses to avoid confusion and to more closely align ISA’s standards with the IEC standards.
ANSI/ISA 60079-0 (12.00.01) and the other ISA 60079 series standards help to ease global trade of U.S.-manufactured electrical equipment for use in explosive atmospheres. Among the benefits these standards offer U.S. manufacturers are reduced testing and certification costs and reduced time to market.
The ISA standards are harmonized to the fullest extent possible, by ISA’s SP12 Electrical Equipment for Hazardous Locations Committee, with the IEC 60079 standards. In the U.S., the standards require all electrical equipment to meet requirements for shock and fire hazards, whereas the IEC 60079 series standards do not¾their focus is entirely on explosion hazards.
These standards are essential for industries that have electrical equipment installed in hazardous (classified) locations and/or use electrical equipment to detect, alarm, or otherwise process signals relating to the detection of materials within their combustible ranges. The standards were developed to promote and ensure safe and practical use of such electrical equipment.
Founded in 1945, ISA (www.isa.org) is a leading, global, nonprofit organization that is setting the standard for automation by helping over 30,000 worldwide members and other professionals solve difficult technical problems, while enhancing their leadership and personal career capabilities. Based in Research Triangle Park, North Carolina, ISA develops standards; certifies industry professionals; provides education and training; publishes books and technical articles; and hosts the largest conference and exhibition for automation professionals in the Western Hemisphere. ISA is the founding sponsor of The Automation Federation (www.automationfederation.org).
WBF provides an open forum for the exchange of information related to the management, operation, and automation of manufacturing processes. Created in 1994, members of the non-profit, professional organization include end-users, vendors, consultants and academics. WBF provides organization, management, and structure to facilitate networking among its members and sharing of knowledge and information related to manufacturing processes. WBF documents best practices and guidelines for implementation of standards that apply to batch control and the exchange of batch data, as well as conducting technical conferences and technical training programs. WBF is a founding charter member of The Automation Federation (www.automationfederation.org). More information about WBF is available at www.wbf.org.
OMAC–The Open Modular Architecture Controls Users’ Group (www.omac.org) is an affiliate organization of ISA- The Instrumentation, Systems and Automation Society- and works to collectively derive common solutions for both technical and non-technical issues in the development, implementation, and commercialization of open, modular architecture control (OMAC) technologies, and to facilitate the accelerated development and convergence of industry and government developed OMAC technology guidelines to one set that satisfies common use requirements. OMAC has about 500 member representatives from end-user companies, OEM's, and technology providers and integrator companies. OMAC currently operates three Work Groups: Packaging Machinery, Manufacturing Infrastructure, and Machine Tool. OMAC is a founding charter member of The Automation Federation (www.automationfederation.org).
