Effective Date of New/Revised Requirements

Effective Date (see Schedule below): March 31, 2015

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requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.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):
- Additional insulation material requirements.
- Additional tamper-resistant receptacle requirements.
- Additional Weather-resistant receptacle requirements.
- Additional corrosion resistance requirements.
- Additional marking requirements.
- Additional requirements for outlet devices and attachment plug terminals.

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:

  • September 30, 2014 = 6 Month Report Review – Intertek will review all Reports. Update if compliance is verified or issue Findings Letter/Quote for any re-evaluations needed
  • October 30, 2014 = 5 Month Quote Cut-off – Quotes returned for necessary re-evaluations
  • February 27, 2015 = 30 Day Warning – Client advised of all non-compliant Reports to be Suspended
  • March 31, 2015 = Effective Date – ATM Suspended for all non-compliant Reports

Fees:  An initial review of Listing Report (s) will be covered by a direct billing project and will be invoiced at not more than $1000 per report.

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 – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records.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.
