Effective November 28, 2016
Effective Date (see Processing Schedule below): November 28, 2016
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requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date of November 28, 2016 unless the product is found to comply with new/revised requirements.
Overview of Changes: New test methods for spread spectrum technologies. Identification of UL 2560 requirements considered to be met by a product that already complies with UL 60950-1. Change provides an additional option (the use of a symbol) for marking a device, such as a switch, intended for emergency service. Changes to requirements for products intended for outdoor use. Changes to the battery life test requirements for openings in non-resident-accessible equipment. 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:
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 – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records.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.
