§ 431.224 - Uniform test method for the measurement of energy consumption for traffic signal modules and pedestrian modules.
(a) Scope. This section provides the test procedures for measuring, pursuant to EPCA, the maximum wattage and nominal wattage of traffic signal modules and pedestrian modules. For purposes of 10 CFR part 431 and EPCA, the test procedures for measuring the maximum wattage and nominal wattage of traffic signal modules and pedestrian modules shall be the test procedures specified in § 431.223(b).
(b) Testing and Calculations. Determine the nominal wattage and maximum wattage of each covered traffic signal module or pedestrian module by conducting the test procedure set forth in Environmental Protection Agency, “ENERGY STAR Program Requirements for Traffic Signals,” Version 1.1, section 1, “Definitions,” and section 4, “Test Criteria.” (Incorporated by reference, see § 431.223) Use a wattmeter having an accuracy of ±1% to measure the nominal wattage and maximum wattage of a red and green traffic signal module, and a pedestrian module when conducting the photometric and colormetric tests as specified by the testing procedures in VTCSH 2005.
§ 431.221 - Purpose and scope.
This subpart contains energy conservation requirements for traffic signal modules and pedestrian modules, pursuant to Part B of Title III of the Energy Policy and Conservation Act, as amended, 42 U.S.C. 6291-6309.
§ 431.222 - Definitions concerning traffic signal modules and pedestrian modules.
Basic model means all units of a given type of covered product (or class thereof) manufactured by one manufacturer, having the same primary energy source, and which have essentially identical electrical, physical, and functional (or hydraulic) characteristics that affect energy consumption, energy efficiency, water consumption, or water efficiency.
Maximum wattage means the power consumed by the module after being operated for 60 minutes while mounted in a temperature testing chamber so that the lensed portion of the module is outside the chamber, all portions of the module behind the lens are within the chamber at a temperature of 74 °C and the air temperature in front of the lens is maintained at a minimum of 49 °C.
Nominal wattage means the power consumed by the module when it is operated within a chamber at a temperature of 25 °C after the signal has been operated for 60 minutes.
Pedestrian module means a light signal used to convey movement information to pedestrians.
Traffic signal module means a standard 8-inch (200 mm) or 12-inch (300 mm) traffic signal indication that—
(1) Consists of a light source, a lens, and all other parts necessary for operation; and
(2) Communicates movement messages to drivers through red, amber, and green colors.
Energy Conservation Standards
§ 431.226 - Energy conservation standards and their effective dates.
Any traffic signal module or pedestrian module manufactured on or after January 1, 2006, shall meet both of the following requirements:
(a) Have a nominal wattage and maximum wattage no greater than:
Maximum wattage
(at 74 °C) | Nominal
wattage (at 25 °C) | Traffic Signal Module Type: | 12″ Red Ball | 17 | 11 | 8″ Red Ball | 13 | 8 | 12″ Red Arrow | 12 | 9 | 12″ Green Ball | 15 | 15 | 8″ Green Ball | 12 | 12 | 12″ Green Arrow | 11 | 11 | Pedestrian Module Type: | Combination Walking Man/Hand | 16 | 13 | Walking Man | 12 | 9 | Orange Hand | 16 | 13 |
