§430.2. Definitions. — Inbound Citations

(i) For UEF and first-hour rating testing, electric heat pump circulating water heaters will be tested with a minimally-compliant electric storage water heater (as defined at § 430.2 of this chapter) that has a rated storage volume of between 25 and 35 gallons, and is in the low draw pattern, as determined in accordance with appendix E to subpart B of 10 CFR part 430 and the standards set at § 430.32(d) of this chapter. If the manufacturer certifies the specific model of electric storage water heater used for testing to determine the certified UEF and first-hour rating of the electric heat pump circulating water heater, that model of electric storage water heater will be used for testing. If this is not possible (such as if the electric storage water heater model is no longer available or has been discontinued), testing will be performed with an electric storage water heater that has a minimally-compliant UEF rating, in the low draw pattern, and a rated storage volume that is within ± 3 gallons of the rated storage volume of the electric storage water heater used to determine the certified ratings of the electric heat pump circulating water heater (but not less than 25 gallons and not greater than 35 gallons). If no such model is available, then testing will be performed with a minimally-compliant electric storage water heater that has a rated storage volume of between 25 and 35 gallons and is in the low draw pattern.

(d) Each basic model shall be certified according to the appropriate product category as defined in § 430.2 of this chapter based on compartment volumes and compartment temperatures. If one or more compartments could be classified as both a fresh food compartment and a freezer compartment, the model must be certified to each applicable product category based on the operation of the compartment(s) as both fresh food and freezer compartments.

(1) Compartment volume used to determine product category shall be, for each compartment, the mean of the volumes of that specific compartment for the sample of tested units of the basic model, measured according to the provisions in section 4.1 of appendix A of subpart B of part 430 of this chapter for refrigerators and refrigerator-freezers and section 4.1 of appendix B of subpart B of part 430 of this chapter for freezers, or, for each compartment, the volume of that specific compartment calculated for the basic model in accordance with § 429.72(c).

(2) Determination of the compartment temperature ranges shall be based on operation under the conditions specified and using measurement of compartment temperature as specified in appendix A of subpart B of part 430 of this chapter for refrigerators and refrigerator-freezers and appendix B of subpart B of part 430 of this chapter for freezers. The determination of compartment status may require evaluation of a model at the extremes of the range of user-selectable temperature control settings. If the temperature ranges for the same compartment of multiple units of a sample are different, the maximum and minimum compartment temperatures for compartment status determination shall be based on the mean measurements for the units in the sample.

(E) For an electric storage water heater that has a permanent mode or setting in which it is capable of heating and storing water above 135 °F, where permanent mode or setting means a mode of operation that is continuous and does not require any external consumer intervention to maintain for longer than 120 hours, except for those that meet the definition of “heat pump-type” water heater at § 430.2 of this chapter, whose rated storage volumes are less than 20 gallons or greater than 55 gallons, or that are only capable of heating the stored water above 135 °F in response to instructions received from a utility or third-party demand-response program, the following applies:

(1) To demonstrate compliance with the energy conservation standards in § 430.32(d)(1) of this chapter, any represented value of uniform energy factor shall be determined based on testing in accordance with section 5.1.1 of appendix E to subpart B of 10 CFR part 430.

(2) To demonstrate compliance with the energy conservation standards in § 430.32(d)(2) of this chapter, any represented value of uniform energy factor shall be determined based on high temperature testing in accordance with section 5.1.2 of appendix E to subpart B of 10 CFR part 430.

(d) Each basic model of miscellaneous refrigeration product must be certified according to the appropriate product category as defined in § 430.2 of this chapter based on compartment volumes and compartment temperatures. If one or more compartments could be classified as both a fresh food compartment and a freezer compartment, the model must be certified to each applicable product category based on the operation of the compartment(s) as both fresh food and freezer compartments.

(1) Compartment volume used to determine product category shall be, for each compartment, the mean of the volumes of that specific compartment for the sample of tested units of the basic model, measured according to the provisions in section 4.1 of appendix A of subpart B of part 430 of this chapter, or, for each compartment, the volume of that specific compartment calculated for the basic model in accordance with § 429.72(d).

(2) For compartments other than cooler compartments, determination of the compartment temperature ranges shall be based on operation of the product under the conditions specified in appendix A to subpart B of part 430 of this chapter for miscellaneous refrigeration products. The determination of compartment status may require evaluation of a model at the extremes of the range of user-selectable temperature control settings. If the temperature ranges for the same compartment of multiple units of a sample are different, the maximum and minimum compartment temperatures for compartment status determination shall be based on the mean measurements for the units in the sample.

(1) Measure initial lumen output, input power, initial lamp efficacy, lumen maintenance at 1,000 hours, lumen maintenance at 40 percent of lifetime of a compact fluorescent lamp (as defined in 10 CFR 430.2), color rendering index (CRI), correlated color temperature (CCT), power factor, start time, standby mode energy consumption, and time to failure in accordance with appendix W of this subpart. Express time to failure in hours.

(A) A power factor greater than or equal to 0.7 for integrated LED lamps (as defined in § 430.2) and 0.5 for medium base compact fluorescent lamps (as defined in § 430.2); and

(1) For equipment without doors and without a discharge air grille or discharge air honeycomb, the angle between a vertical line extended down from the highest point on the manufacturer's recommended load limit line and the load limit line itself, when the equipment is viewed in cross-section; and

(b) Mechanical ventilation fans that are integral to heating, ventilating, and air conditioning equipment, including furnace fans as defined in § 430.2 of this subchapter, are not subject to the efficiency requirements in paragraph (a) of this section.
