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requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.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

  • Added new performance requirements for Spillage on vents, slots or openings and Under Counter Appliances.
  • Added requirement for built-in ovens to employ a main “off” switch.
  • Added requirements for a secondary line break of surface elements.
  • Added lower surface temperature limits.
  • Added marking and user instruction requirements for built-in wall ovens, attached to cabinetry, and rated 120V, 1.75 kW (14.6A) or less. 
  • Added requirements for Smart enabled appliances.

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:

  • November 23, 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
  • January 25, 2016 = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations
  • June 24, 2016 = 30 Day Warning – Client advised of all non-compliant Reports to be Suspended
  • July 24, 2016 = 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).

New section added;
(Added on July 24, 2013)

Spillage on vents, slots, or openings
75.5.1 An appliance having vents, slots, or openings on or near the horizontal cooking surface as referenced in 6.4.5 is to be subjected to the spill test in 75.5.2 to simulate conditions that might occur during actual use. There shall be no evidence of arcing, short-circuiting, insulation breakdown, or unintended operation. After the test, the appliance shall comply with the dielectric voltage-withstand requirements in 66.1.
75.5.2 Using the solution described in 75.1.2, pour the salt-water solution down any series of openings (vent, slot, gap, groove, crevice, etc.) that could receive water from a spill at a steady rate while steadily moving back and forth along the length of the opening. Each control is then to be operated through its full range and this operation is to be repeated after a 5 min interval. Within 5 min but no less than 1 min after the repeated series of operations, the appliance is to be tested for compliance with Dielectric Voltage-Withstand Test, Section 66.

Each control is then to be run through various modes of operations so that all components (fans, switches, relays, etc.) have been activated. Within 5 min but no less than 1 min after the series of operations, the appliance is to be tested for compliance with the Dielectric Voltage-Withstand Test, Section 66.
