45、sified) Locations. It is the Third edition of CSA-C22.2 No. 213 and the Ninth edition of UL 121201. This edition of CSA-C22.2 No. 213 supersedes the previous edition published in 2016. This edition of UL 121201 supersedes the previous ISA-12.12.01-2015 edition published on August 21, 2015.This harmo
46、nized standard was prepared by the CSA Group and Underwriters Laboratories Inc. (UL).Efforts have been made to synchronize the UL edition number with that of the previous corresponding ISAstandard with which this standard is now harmonized with CSA. As a result, one or more UL editionnumbers have be
47、en skipped to align per the previous ISA edition number.The ISA-12.12.01-2015 standard is being maintained until September 15, 2022 for reference purposesonly.This standard is considered suitable for use for conformity assessment within the stated scope of thestandard.This standard was reviewed by t
48、he CSA Integrated Committee on Hazardous Location Products, underthe jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic SteeringCommittee on Requirements for Electrical Safety, and has been formally approved by the CSA TechnicalCommittee.This standard has been a
49、pproved by the American National Standards Institute (ANSI) as an AmericanNational Standard.Application of StandardWhere reference is made to a specific number of samples to be tested, the specified number is to beconsidered a minimum quantity.Note: Although the intended primary application of this standard is stated in its scope, it is important to note thatit remains the responsibility of the users of the standard to judge its suitability for their particular purpose.Level of HarmonizationThis stand
