# §429.46. Commercial clothes washers.

- (a) **Sampling plan for selection of units for testing.**
  - (1) The requirements of [§ 429.11](/cfr/10/429.11.md) are applicable to commercial clothes washers; and
  - (2) For each basic model of commercial clothes washers, a sample of sufficient size shall be randomly selected and tested to ensure that—
    - (i) Any represented value of the integrated water factor or other measure of energy or water consumption of a basic model for which consumers would favor lower values shall be greater than or equal to the higher of:
      - (A) **The mean of the sample, where—** Or,
      - (B) The upper 97 1/2 percent confidence limit (UCL) of the true mean divided by 1.05, where:
    - (ii) Any represented value of the modified energy factor, active-mode energy efficiency ratio, water efficiency ratio, or other measure of energy or water consumption of a basic model for which consumers would favor higher values shall be greater than or equal to the higher of:
      - (A) **The mean of the sample, where—** Or,
      - (B) The lower 97 1/2 percent confidence limit (LCL) of the true mean divided by 0.95, where:
  - (3) The clothes container capacity of a basic model reported in accordance with [paragraph (b)(2)](#b-2) of this section shall be the mean of the measured clothes container capacity (C) of all tested units of the basic model.
  - (4) The corrected remaining moisture content (RMC) of a basic model reported in accordance with [paragraph (b)(2)](#b-2) of this section shall be the mean of the final RMC value measured for all tested units of the basic model.
- (b) **Certification reports.**
  - (1) The requirements of [§ 429.12](/cfr/10/429.12.md) are applicable to commercial clothes washers; and
  - (2) Pursuant to [§ 429.12(b)(13)](/cfr/10/429.12.md?p=b-13), a certification report shall include the following public product-specific information:
    - (i) The modified energy factor (MEFJ2), in cubic feet per kilowatt-hour per cycle (cu ft/kWh/cycle);
    - (ii) The integrated water factor (IWF), in gallons per cycle per cubic feet (gal/cycle/cu ft);
    - (iii) The clothes container capacity, in cubic feet (cu ft);
    - (iv) The type of loading (top-loading or front-loading); and
    - (v) **The corrected RMC (expressed as a percentage).**
- (c) **Reported values.** Values reported pursuant to this section must be rounded as follows: Clothes container capacity to the nearest 0.1 cu ft, and corrected RMC to the nearest 0.1 percentage point.
