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requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date of March 27, 2017 unless the product is found to comply with new/revised requirements.

Overview of Changes: These revisions to UL 60730-2-2 are being issued to revise the endurance test and add requirements covering deviation and drift to provide a performance/reliability bench mark for thermal motor protectors when tested to the manufacturer’s declared electrical and thermal rating.. Specific details of new/revised requirements are found in table below.

Processing Schedule: So that production of products bearing Listing Marks will not be interrupted, the following schedule of approximate dates has been established to ensure Listing Reports are found compliant by Effective Date:

  • July 27, 2017 = 8 Month Report Review – Intertek will review all Reports. Update if compliance is verified or issue Findings Letter/Quote for any re-evaluations needed
  • September 27, 2017 = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations
  • February 27, 2017 = 30 Day Warning – Client advised of all non-compliant Reports to be Suspended
  • March 27, 2017 = 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 Intertek Engineer with review of your Certification Reports, please submit technical information in response to the new/revised paragraphs noted in the attached or explain why these new/revised requirements 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 – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records.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.

Eighteen samples of the tubular style insulation are to be conditioned in accordance with Table 13.101DV. Three samples are to be installed either on protectors or on metal mandrels representative of the size and shape of the protector to be insulated and submitted to the 18-day test described in Table 13.101DV. Fifteen samples are to be 4 inches (102 mm) diameter or square in the minimum thickness used or is to be of a size representative of the end-use protector and subjected to the other tests in Table 13.101DV.
