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requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.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

  • New and Revised requirements for direct plug-in nightlights with child-appealing qualities
  • Requirements for isolated output LED drivers
  • Requirements for nightlights with vessels containing liquid
  • Revised component breakdown requirements
  • Requirements for devices that rotate to permit adjustable positioning after insertion into an outlet receptacle

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:

  • December 16, 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
  • February 21, 2017 = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations
  • August 21, 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).

7.1.11 New requirement – Removable parts of nightlight with child-appealing features not to be risk of injury from sharp edge. Test per Section 10.7
7.1.12 New requirement – Quoted:

“In the United States, an accessible liquid coating material (such as paint, enamel, lacquer, ink, and the like) applied to direct plug-in nightlights with child-appealing features shall not contain compounds of lead, antimony, arsenic, barium, cadmium, chromium, mercury, or selenium exceeding amounts specified in ASTM F963. A liquid coating material is considered to be accessible if it can be contacted by persons before or after compliance with the performance requirements described in the Mold Stress-Relief Distortion Test, Clause 10.4, and the Enclosure Impact Test,
Clause 10.7.
Note 1: In Canada, various requirements in jurisdictions such as federal, provincial, or municipal may apply.
Note 2: The requirements for a liquid coating material do not apply to ink applied to a packing material.”

Note: - Coating materials used on nightlights with child-appealing properties, as defined, shall not contain compounds of lead, antimony, arsenic, barium, cadmium, chromium, mercury, or selenium exceeding amounts specified in Standard Consumer Safety Specification for Toy Safety, ASTM F963.

If nightlight contains these coating materials, manufacturer will need to provide COA (Certificate of Compliance) stating compliance with requirements of above standard. If COA is not provided, a separate project will be initiated to conduct the necessary testing.
