(a)Sampling plan for selection of units for testing.
(1)The requirements of § 429.11 are applicable to fluorescent lamp ballasts; and
(2)For each basic model of fluorescent lamp ballasts, a sample of sufficient size, not less than four, shall be randomly selected and tested to ensure that—
(i)Any represented value of the energy 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 99 percent confidence limit
(UCL)of the true mean divided by 1.01, where: and
(ii)Any represented value of the ballast luminous efficiency, power factor, or other measure of the energy efficiency or energy consumption of a basic model for which consumers would favor a higher value must be less than or equal to the lower of:
(A)The mean of the sample, where: Or,
(B)The lower 99 percent confidence limit
(LCL)of the true mean divided by 0.99, where:
(iii)The represented value of average total lamp arc power must be equal to the mean of the sample, Where: x is the sample mean; n is the number of units in the sample; and xi is the ith unit.
(b)Certification reports.
(1)The requirements of § 429.12 are applicable to fluorescent lamp ballasts; and
(2)Pursuant to § 429.12(b)(13), a certification report must include the following public product-specific information: The ballast luminous efficiency, the average total lamp arc power, the power factor, the number of lamps operated by the ballast, and the type of lamps operated by the ballast (i.e., wattage, base, shape, diameter, and length).
(c)Rounding requirements.
(1)Round ballast luminous efficiency to the nearest thousandths place.
(2)Round power factor to the nearest hundredths place.
(3)Round average total lamp arc power to the nearest tenth of a watt. [76 FR 12451, Mar. 7, 2011; 76 FR 24769, May 2, 2011, as amended at 81 FR 25600, Apr. 29, 2016; 85 FR 56493, Sept. 14, 2020]
