The Energy Policy and Conservation Act (EPCA) requires the development of test procedures for the meas-urement of the energy efficiencies and the computation of Estimated Annual Operating Costs -(EAOC ' s) of consumer products covered by the EPCA.These products are refrigerators, refrigerator freezers, dishwashers, clothes dryers, water heaters, room air conditioners, home heating equipment, television sets, kitchen ranges and ovens, clothes washers, hiomidif iers , dehumidifiers, central air conditioners and furnaces Each test procedure contains one or more factors that are determined by the consumer's usage conditions and include such items as uses per year, outdoor and indoor environment, household operating practices and ground water temperature This report is a compilation of the sources and background for the consumer usage factors contained in the current test procedures. Uncertainties in these factors are discussed, and for selected base cases , the corresponding 'uncertainties in EAOC ' s are computedThe purpose of the report is to provide perspective in selecting usage factors for future study and refinement.The items found to be most in need of refinement were factors bearing on temperature and humidity control and on water heating, both on national and regional bases.

The photolysis of CD&O at 313 nm in the presence of neopentane was carried out over the temperature range 576-706 K. Analysis of the products and isotopic analysis of the methanes demonstrate abstraction of H from neopentane and D from CD&O by methylene. The relative kinetics of abstraction of H and D have been measured over the temperature range, and the absolute value for the collision yield of the abstraction of H from neopentane by CD2 at 653 K has been been estimated to be about 1.5 X 10" mole-' cm3 sec-l, a value 103 times larger than the corresponding reaction of CH3.
