# §305.10. Determinations of capacity.


The capacity of covered products shall be determined as follows:

- (a) **Refrigerators and refrigerator-freezers.** The capacity shall be the total refrigerated volume (VT) in cubic feet, rounded to the nearest one-tenth of a cubic foot, as determined according to appendix A to [10 CFR part 430](/cfr/10/part430.md), subpart B.
- (b) **Freezers.** The capacity shall be the total refrigerated volume (VT) in cubic feet, rounded to the nearest one-tenth of a cubic foot, as determined according to appendix B to [10 CFR part 430](/cfr/10/part430.md), subpart B.
- (c) **Dishwashers.** The capacity shall be the place-setting capacity, determined according to appendix C to [10 CFR part 430](/cfr/10/part430.md), subpart B.
- (d) **Water heaters.** The capacity shall be the rated storage volume and first hour rating (for storage-type models), and gallons per minute (for instantaneous-type models), as determined according to appendix E to [10 CFR part 430](/cfr/10/part430.md), subpart B.
- (e) **Pool heaters.** The capacity shall be the heating capacity in Btu's per hour, rounded to the nearest 1,000 Btu's per hour, as determined according to appendix P to [10 CFR part 430](/cfr/10/part430.md), subpart B.
- (f) **Room air conditioners and portable air conditioners.** The capacity for room air conditioners and portable air conditioners shall be determined according to [10 CFR part 430](/cfr/10/part430.md), [subpart B](/cfr/16/subpartB.md), with rounding determined in accordance with [10 CFR part 430](/cfr/10/part430.md).
- (g) **Clothes washers.** The capacity shall be the tub capacity as determined according to Department of Energy test procedures in [10 CFR part 430](/cfr/10/part430.md), [subpart B](/cfr/16/subpartB.md), expressed in terms of “Capacity (tub volume)” in cubic feet, rounded to the nearest one-tenth of a cubic foot, and the capacity class designations “standard” or “compact.”
- (h) **Furnaces.** The capacity shall be the heating capacity in Btu's per hour, rounded to the nearest 1,000 Btu's per hour, as determined according to appendix N to [10 CFR part 430](/cfr/10/part430.md), subpart B.
- (i) **Central air conditioners, cooling.** The capacity shall be the cooling capacity in Btu's per hour, as determined according to appendix M to [10 CFR part 430](/cfr/10/part430.md), [subpart B](/cfr/16/subpartB.md), rounded to the nearest 100 Btu's per hour for capacities less than 20,000 Btu's per hour; to the nearest 200 Btu's per hour for capacities between 20,000 and 37,999 Btu's per hour; and to the nearest 500 Btu's per hour for capacities between 38,000 and 64,999 Btu's per hour.
- (j) **Central air conditioners, heating.** The capacity shall be the heating capacity in Btu's per hour, as determined according to appendix M to [10 CFR part 430](/cfr/10/part430.md), [subpart B](/cfr/16/subpartB.md), rounded to the nearest 100 Btu's per hour for capacities less than 20,000 Btu's per hour; to the nearest 200 Btu's per hour for capacities between 20,000 and 37,999 Btu's per hour; and to the nearest 500 Btu's per hour for capacities between 38,000 and 64,999 Btu's per hour.
- (k) **Fluorescent lamp ballasts.** The capacity shall be the ballast input voltage, as determined according to appendix Q to [10 CFR part 430](/cfr/10/part430.md), subpart B.
- (l) **Ceiling fans.** The capacity shall be the airflow in cubic feet per minute as determined according to appendix U of [10 CFR part 430](/cfr/10/part430.md), subpart B.
