Title 42 › CHAPTER 77 — ENERGY CONSERVATION › SUBCHAPTER III — IMPROVING ENERGY EFFICIENCY › Part A — Energy Conservation Program for Consumer Products Other Than Automobiles › § 6293
The Secretary must keep the test methods that were in effect on March 17, 1987, until they are changed. At least once every 7 years the Secretary must review test methods for all covered products and either update them if needed or publish a notice saying no change. The Secretary can create tests for any covered product, must ask the National Institute of Standards and Technology for help, and must publish proposed test methods so people can comment. The public comment period must be at least 60 days and can be extended up to 270 days. Tests must measure energy use or efficiency, water use for showerheads, faucets, toilets and urinals, or estimated yearly operating cost during normal use, and must not be too hard to run. If a test gives estimated yearly cost, it must use measured energy or water use and representative average unit costs that the Secretary provides. Companies may not make written or broadcast claims about a product’s energy use, efficiency, water use, or operating cost unless the product was tested under the applicable test method and the claim fairly shows the test results. After a new or changed test is set, companies have 180 days to follow it; a company can petition for an extension up to another 180 days if it files not later than the 60th day before the 180-day period ends and the Secretary agrees hardship exists. For many specific products the law points to industry test standards (for example, certain ANSI, ASME, Energy Star, NEMA, ASTM, and ASHRAE methods) for items like fluorescent ballasts (for those made on or after January 1, 1990), lamps, showerheads, faucets, water closets and urinals, exit signs, transformers, traffic-signal modules, medium-base compact fluorescent lamps, dehumidifiers, prerinse spray valves, refrigerated vending machines, ceiling fans and light kits, class A external power supplies, and metal halide ballasts. If no workable test can be made, the Secretary can publish that finding and its reasons. If a new test changes how efficiency or use is measured, the Secretary must adjust the energy conservation standard using test results from representative models, and older models that complied before the change are treated as complying with the new standard. The Secretary had to set testing rules for refrigerated bottled or canned beverage vending machines within 2 years after August 8, 2005, using industry methods when possible.
