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requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.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

  • Requirements for Plenum Use in Paragraphs 1.5, 7.6.13, and 72.21
  • Requirements for Products with E-Ballast Ratings of 347 Vac in Paragraphs 51.1, 51.3 and Tables 51.2
  • Requirements for Products with E-Ballast Ratings Greater Than 347 Vac in Paragraphs 51.5 and 51.6

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:

  • February 2, 2016 = 8-9 Month Report Review – Intertek will review all Reports. Update if compliance is verified or issue Findings Letter/Quote for any re-evaluations needed
  • April 25, 2016 = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations
  • September 26, 2016 = 30 Day Warning – Client advised of all non-compliant Reports to be Suspended
  • October 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).

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 – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records.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

1.5InfoNew clause added;

Controls intended to be installed in air handling spaces or in other environmental air space (plenums) are covered under the scope of this standard.
7InfoFrame and Enclosure
7.6InfoNonmetallic
7.6.13 New clause added;

Electrical controls employing polymeric parts that are intended to be installed in air handling spaces or in other environmental air space (plenums) shall be investigated for the application and their fire-resistance and low-smoke-producing characteristics in accordance with the Standard for Fire Test for Heat and Visible Smoke Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces, UL 2043.
72InfoGeneral (Markings)
72.21 New clause added;

Electrical controls intended for use in air handling spaces shall be marked with the following: "Suitable for Use In Air Handling Spaces" or "Suitable for Use in Other Environmental Air Space (Plenums) in Accordance with Section 300.22, (C) of the National Electrical Code".
51InfoElectronic Ballast, CFLs and LED Driver Rated Controls
Table 51.2 New table added for Products with E-Ballast Ratings of 347 Vac;

Peak current requirements with pulse width less than or equal to 2.35 ms for endurance test (see standard for specific values).
51.1 Additions to existing requirements are underlined below.

A control intended for use with electronic ballasts, self ballasted LED and Compact Fluorescent Lamps, LED drivers and similar loads with capacitive load characteristics, having a rated current (steady state current) and rated voltage in accordance with Table 51.1 and/or Table 51.2 shall be marked in accordance with 72.20.
51.3 Additions to existing requirements are underlined below.

The series coil values must be adjusted based on the input line characteristics to achieve the peak currents listed in Table 51.1 or Table 51.2. The series coil shall be sized such that it does not saturate during testing and shall be able to handle the resulting power dissipation with less than 10°C temperature rise. Peak current and pulse width are illustrated in Figure 51.2.
51.5 New clause added;

For products rated in excess of 347 Vac, the controls shall be tested with the specific model of electronic ballast(s) they are intended to control. The manufacturer’s name and model number of the electronic ballast(s) with which the control is intended to be used shall be marked either on the product or provided with the control on the packaging or stuffer sheet.
51.6 New clause added;

The characteristics of the waveform (peak currents and pulse width) shall be recorded using an oscilloscope.

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.
