25、IBUTION WITHOUT PERMISSION FROM UL General Notes This is the common ISA and UL Standard for the General Requirements for Electrical Ignition Systems for Internal Combustion Engines in Class I, Division 2 or Zone 2, Hazardous (Classied) Locations. It is the rst edition of ANSI/ISA-12.20.01 and the rs
26、t edition of ANSI/UL 122001. The document is a modication of the ISA document to create the equivalent UL version and maintain the ANSI approval of this standard. ANSI/ISA-12.20.01 and ANSI/UL 122001 contain identical requirements, and identical publication dates. This common Standard was prepared b
27、y ISA The International Society of Automation on May 4, 2009 but is now being maintained by Underwriters Laboratories (UL). Note: Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard
28、 to judge its suitability for their particular purpose. UL Effective Date The requirements in this standard are effective August 29, 2014. A UL effective date is one established by Underwriters Laboratories Inc. and is not part of the ANSI approved standard. AUGUST 29, 2014 ISA-12.20.01-2009 (R2014)

This document has been prepar
30、ed as part of the service of ISA towards a goal of uniformity in the eld of instrumentation. To be of real value, this document should not be static but should be subject to periodic review. Toward this end, the Society welcomes all comments and criticisms and asks that they be addressed to the Secr
31、etary, Standards and Practices Board; ISA; 67 Alexander Drive; P. O. Box 12277; Research Triangle Park, NC 27709; Telephone (919) 549-8411; Fax (919) 549-8288; E-mail: standardsisa.org. The ISA Standards and Practices Department is aware of the growing need for attention to the metric system of unit
32、s in general, and the International System of Units (SI) in particular, in the preparation of instrumentation standards. The Department is further aware of the benets to USA users of ISA standards of incorporating suitable references to the SI (and the metric system) in their business and profession
33、al dealings with other countries. Toward this end, this Department will endeavor to introduce SI-acceptable metric units in all new and revised standards, recommended practices, and technical reports to the greatest extent possible. Standard for Use of the International System of Units (SI): The Mod
34、ern Metric System, published by the American Society for Testing & Materials as IEEE/ASTM SI 10-97, and future revisions, will be the reference guide for denitions, symbols, abbreviations, and conversion factors. It is the policy of ISA to encourage and welcome the participation of all concerned ind
35、ividuals and interests in the development of ISA standards, recommended practices, and technical reports. Participation in the ISA standards-making process by an individual in no way constitutes endorsement by the employer of that individual, of ISA, or of any of the standards, recommended practices
36、, and technical reports that ISA develops.
