The energy input rate test is used to confirm that the powered sink is operating properly prior to further testing.

Preheat energy and time can be useful to food service operators to manage power demands and to know how quickly the powered sink can be ready for operation when filled with cold water.

Note 2—It is typically recommended that powered sinks be filled with hot water prior to use. This test is useful for operations that have a limited supply of domestic hot water and would need to use cold water to fill the sink to capacity.

Idle energy rate and pilot energy rate can be used to estimate energy consumption during standby periods.

Washing cycle energy consumption can be used by the food service operator to estimate energy consumption during operating periods.

1.1 This test method evaluates the energy consumption of powered open warewashing sinks. The food service operator can use these tests to evaluate and select a suitable washing device and understand its energy consumption.

1.2 This test method applies to powered open warewashing sinks (powered sinks) with the following characteristics: a large main water sink with electrically powered water pump(s) and multiple high flow water nozzles. The unit may include gas or electric heaters to maintain water temperature. These powered sinks are designed to run for predetermined cycle duration and accommodate pots and pans of various shapes and sizes as well as cooking utensils. They are intended for stand alone use and require little supervision. The powered sink will be tested for the following (where applicable):

1.2.1 Maximum energy input rate (10.2),

1.2.2 Preheat energy consumption and duration (10.3),

1.2.3 Idle energy rate (10.4),

1.2.4 Pilot energy rate, if applicable (10.5), and

1.2.5 Washing cycle energy consumption (10.6).

Note 1—This test method applies only to the powered portion of the unit. Other compartments (sanitizing, rinsing, and so forth) are not evaluated.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
