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requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.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):

  • Add requirements for metal of lampholder screwshell device bases
  • Change of material requirement to end product requirement
  • Addition of higher temperature requirements for small coil assemblies (less than 250 gm) for inductor thermal measurement method in temperature test
  • Addition of Supplement SA – Supplemental Requirements for Light Emitting Diodes (LED)

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:

  • April 10, 2015 = 8 Month Report Review – Intertek will review all Reports. Update if compliance is verified or issue Findings Letter/Quote for any re-evaluations needed
  • June 8, 2015 = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations
  • November 6, 2015 = 30 Day Warning – Client advised of all non-compliant Reports to be Suspended
  • December 4, 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 – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records.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.

 
Description of New/Revised Technical Requirements

NOTE: Additions to existing requirements are underlined and deletions are shown lined out below.

ClauseVerdictComment
1.3 -

New clause added (All LED type products identified in Section 1.3 will need to be evaluated to Supplement SA); 

These requirements also include Supplemental Requirements for Light-Emitting Diodes (LED), Supplement SA, for:

a) Self-contained LED lamps, rated 120 to 347 V AC nominal for connection to screw-, pinbase, and recessed single contact (RSC or R7) lampholders,

b) Lamps for replacement of an ANSI standardized fluorescent lamp, and consisting of lightemitting- diode (LED) lamp technologies, with control circuitry, and a driver or power supply. The LED driver and control circuitry will be either integral with the lamp or remote from the lamp,and

c) Component LED lamps, with or without control circuitry, an ANSI base other than bases mentioned in (a), for connection to LED driver having a low voltage output, such as replacement for tungsten-halogen, MR11 and MR16 shaped lamps.
