Appendix W to Subpart B of Part 430—Uniform Test Method for Measuring the Energy Consumption of Medium Base Compact Fluorescent Lamps
1. Scope: This appendix covers the test requirements used to measure the initial efficacy, lumen maintenance at 1,000 hours, lumen maintenance at 40 percent of rated life, rapid cycle stress, and lamp life of medium base compact fluorescent lamps.
2. Definitions:
a. Average rated life means the length of time declared by the manufacturer at which 50 percent of any large number of units of a lamp reaches the end of their individual lives.
b. Initial performance values means the photometric and electrical characteristics of the lamp at the end of 100 hours of operation. Such values include the initial efficacy, the rated luminous flux and the rated lumen output.
c. Lumen maintenance means the luminous flux or lumen output at a given time in the life of the lamp and expressed as a percentage of the rated luminous flux or rated lumen output, respectively.
d. Rated luminous flux or rated lumen output means the initial lumen rating (100 hour) declared by the manufacturer, which consists of the lumen rating of a lamp at the end of 100 hours of operation.
e. Rated supply frequency means the frequency marked on the lamp.
f. Rated voltage means the voltage marked on the lamp.
g. Rated wattage means the wattage marked on the lamp.
h. Self-ballasted compact fluorescent lamp means a compact fluorescent lamp unit that incorporates, permanently enclosed, all elements that are necessary for the starting and stable operation of the lamp, and does not include any replaceable or interchangeable parts.
3. Test Apparatus and General Instructions: The test apparatus and instructions for testing medium base compact fluorescent lamps shall conform to the requirements specified in section 2, “Definitions,” section 3, “Referenced Standards,” and section 4, “CFL Requirements for Testing,” of DOE's “ENERGY STAR Program Requirements for [Compact Fluorescent Lamps] CFLs,” Version dated August 9, 2001, (commonly referred to as Version 2.0), (Incorporated by reference, see § 430.22). Record measurements at the resolution of the test instrumentation. Round off calculations to the same number of significant digits as the previous step. Round the final energy consumption value, as applicable, to the nearest decimal place or whole number as follows:
(i) A fractional number at or above the midpoint between two consecutive decimal places or whole numbers shall be rounded up to the higher of the two decimal places or whole numbers; or
(ii) A fractional number below the midpoint between two consecutive decimal places or whole numbers shall be rounded down to the lower of the two decimal places or whole numbers. Round the final initial efficacy to one decimal place. Round the final lumen maintenance at 1,000 hours to a whole number. Round the final lumen maintenance at 40 percent of rated life, the final rapid cycle stress, and the final lamp life for medium base compact fluorescent lamps to whole numbers.
4. Test Measurement: Measure the initial efficacy expressed in lumens per watt; lumen maintenance at 1,000 hours expressed in lumens; lumen maintenance at 40 percent of rated life expressed in lumens; rapid cycle stress expressed in the number of lamps that meet or exceed the minimum number of cycles; and lamp life expressed in hours in accordance with the test requirements specified in section 4, “CFL Requirements for Testing” of DOE's “ENERGY STAR Program Requirements for [Compact Fluorescent Lamps] CFLs,” Version dated August 9, 2001 (Incorporated by reference, see § 430.22).
