Effective Date of New/Revised Requirements

Effective Date (see Schedule below): July 20, 2017

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requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.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:Addition of requirements for Electronic Circuits. Specific details of new/revised requirements are found in table below.

If the applicable requirements noted in the table are not described in your report(s), these requirements will need to be confirmed as met and added to your report(s) such as markings, instructions, test results, etc. (as required).

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 18, 2016 = 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 20, 2017 = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations
  • July 20, 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 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 – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records.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
--Additions to existing requirements are underlined and deletions are shown lined out below
4.38InfoSAFETY CRITICAL FUNCTION – Control, protection and monitoring functions which are being relied upon to reduce the risk of fire, electric shock or casualty hazards.
22.2.1 Except as noted in 22.2.2 – 22.2.8, a motor shall be provided with overload protection that complies with one of the following:
a) Thermal protection (both running-overload and locked-rotor) complying with the requirements in the Standard for Overheating Protection for Motors, UL 2111 or with the Standard for Thermally Protected Motors, UL 1004-3.
b) Impedance protection complying with the Standard for Impedance Protected Motors, UL 1004-2, when tested as used in the application.
c) A sensing circuit that serves to disconnect power from the motor to protect it against overheating using the temperature criteria in UL 2111 or with the Standard for Thermally Protected Motors, UL 1004-3. This sensing circuit shall be the one used to shut down the motor when it does not perform its intended function. The sensing circuit is to be evaluated as a safety circuit and shall be investigated with motor combination complying with the Standard for Electronically Protected Motors, UL 1004-7, or the requirements in the Requirements for the Evaluation of Electronic Circuits, Supplement SA.
d) Secondary circuit motors rated less than 100 volts or less than 200 volt-amperes and tested in accordance with Secondary circuit motors, 59.2.
25.2 A temperature-limiting control used to limit the temperature of a heater during abnormal operation shall comply with:
a) The Standard for Temperature-Indicating and -Regulating Equipment, UL 873;
b) The Standard for Limit Controls, UL 353;
c) The Standard for Automatic Electrical Controls for Household and Similar Use,
Part 1: General Requirements, UL 60730-1; and
d) The Standard for Automatic Electrical Controls for Household and Similar Use;
Part 2: Particular Requirements for Temperature Sensing Controls, UL 60730-2-9.
e) The circuits requirements in the Requirements for the Evaluation of Electronic Circuits, Supplement SA. See 32.11.
Exception: This requirement does not apply to products that do not result in a fire when the control is defeated during the Abnormal Operation Test, Section 59.
32.15 Any control or circuit function whereby a loss/malfunction of its functionality would represent an unacceptable risk of fire, electric shock, or casualty hazards would be considered a Safety Critical Function. See Safety Critical Functions, Section 5 for the most common Safety Critical Functions anticipated by this standard. An electronic circuit that complies with the Requirements for the Evaluation of Electronic Circuits, Supplement SA is considered to fulfill the requirements of a control.

CUSTOMERS PLEASE NOTE: This Table and column "Verdict" can be used in determining how your current or future production is or will be in compliance with new/revised requirements.
