(a) Scope. This section provides the test procedures for measuring, pursuant to EPCA, the daily energy consumption in kilowatt hours per day (kWh/day) or energy efficiency for a given product category and volume or total display area equipment category of commercial refrigerators, freezers, and refrigerator-freezers.

(b) Testing and calculations.

(1) Determine the daily energy consumption and volume or total display area of each covered commercial refrigerator, freezer, or refrigerator-freezer by conducting the appropriate test procedure set forth below

,

in appendix

A or

B, to this subpart. The daily energy consumption of commercial refrigeration equipment shall be calculated using raw measured values and the final test results shall be reported in increments of 0.01 kWh/day.
