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requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.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: CSA C22.2 No. 166-15, Stage and Studio Luminaires, which supersedes the previous edition, CSA C22.2 No. 166-M1983, and incorporates requirements from CSA TIL B-42A, Interim Certification Requirements for Guarding of Non-Lensed Tungsten-Halogen Luminaires.

The changes, with respect to the previous edition of the standard, are major updates, including revised construction, testing, and marking requirements for stage and studio luminaires. A partial re-evaluation will be necessary in most cases.

This SUN is based on CSA Notice; Lighting Products No. 83

If the applicable requirements noted in the table are not described in your report(s), these requirements will need to be confirmed as met and added to your report(s) such as markings, instructions, test results, etc. (as required).

Schedule: So that shipping of products with Listing Marks will not be interrupted, an approximate schedule has been established to ensure Listing Reports are found compliant by Effective Date:

  • May 2, 2016 = 8 Month Report Review – Intertek will review all Reports. Update if compliance is verified or issue Findings Letter/Quote for any re-evaluations needed
  • July 1, 2016 = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations
  • December 1, 2016 = 30 Day Warning – Client advised of all non-compliant Reports to be Suspended
  • January 1, 2017 = Effective Date – ATM Suspended for all non-compliant Reports

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).
