8th Edition Revised May 26, 2009
Effective Date of New/Revised Requirements

Effective Date: December 30, 2016

Impact, Overview, Fees and Action Required

Impact Statement: A review of all Listing Reports is necessary to determine which products comply with new/revised requirements and which products will require re-evaluation. NOTE: Effective immediately, this revised standard will be exclusively used for evaluation of new products unless the Applicant requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.

Overview of Changes: (Specific details of new/revised requirements are found in table below):

  • Rearrangement to include separate sections for each type of cord set, including those using connectors complying with requirements in CAN/CSA-C22.2 No. 60320-1; 
  • New requirements that will require retesting; and 
  • Requirements that have been added from other standards that were referenced in the previous edition C22.2 No 21-95 (R2009) 

The content in this SUN is based on the CSA Certification Notice for wiring devices No. 101 dated May 5, 2015.

Fees: So that production of products bearing the Listing Mark will not be interrupted, a quote will be issued for the Applicant to work with their local Intertek Lab to determine the necessary test program, sampling requirement and needed construction details and/or updated marking/instruction details.

Client Action Required:

Information – To assist our Engineer with review of your Listing Reports, please submit technical information in response to the new/revised paragraphs noted in the attached or explain why these new/revised requirements do not apply to your product (s).

Current Listings Not Active? – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records. We will do this at no charge as long as Intertek is notified in writing prior to the review of your reports.
