Effective February 27, 2015
ADDENDUM: This ADDENDUM replaces SUN issued March 2012 and November 8, 2013: Extension of effective date to 27, 2015.
Effective Date (see Schedule below): February 27, 2015
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 requestsin writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date of February 27, 2015 unless product is found to comply with new/revised requirements.
Overview of Changes: Significant new and revised requirements are contained in the new 4th Edition of UL 1995. Refer to page tr1-tr3 of the 4th Edition and refer to a synopsis of new/revised clauses in table below.
Processing Schedule: So that production of products bearing Listing Marks will not be interrupted, the following schedule has been established to ensure Listing Reports are found compliant by Effective Date:
- May 2, 2014 = 8 Month Report Identification – Intertek will identify all UL 1995/CSA 236-11 Certification Reports and provide to the customer’s Account Representative for preparation of the necessary quotations.
- July 4, 2014 = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations.
- October 31, 2014 = 30 Day Warning – Client advised of all non-compliant Reports to be Suspended.
- February 27, 2015 = Effective Date – ATM Suspended for all non-compliant Reports.
Fees: Due to the magnitude and severity of the new/revised requirements in UL 1995/CSA C22.2 No. 236, quotations will be prepared for the review and possible re-tests anticipated. SVN will only identify valid Certification Reports for each customer and will not be conducting any up-front review and direct-invoicing as is norm.
Client Action Required: Submit Information – To assist the Intertek Engineer with evaluation of your Reports, please submit technical information in response to the new/revised paragraphs noted in the attached.
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 – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records.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.
NOTE: Additions to existing requirements are underlined and deletions are shown lined out below.
