This standard establishes standard methods for measuring performance and includes sections on definitions, test conditions, tests for standard measurements, performance tests, and safety which apply to room air conditioners as defined in 3.1.

Performance tests for Heating-Cooling Units (Section 7) apply to units designed as air-toair source heat pumps with or without supplementary electric resistance heat. The tests do not apply to units with electric resistance as the only heat source.

PURPOSE

This standard establishes a uniform, repeatable procedure or standard method for measuring specified product characteristics of room air conditioners.

The standard methods and the recommended levels of performance, where they appear, are intended to provide a means to compare and evaluate different brands and models of room air conditioners regarding characteristics significant to product use.

The standard methods and the recommended levels of performance are not intended to preclude the exercise of ingenuity or to prevent improvement and innovation in design and performance.
