Standard Test Method for Performance of Water-Bath Rethermalizers



Want this as a site license?


1.1 This test method covers the energy consumption and rethermalizing performance of floor-model and countertop water-bath rethermalizers. The food service operator can use this evaluation to select a water-bath rethermalizer and understand its energy consumption and production capacity.

1.2 This test method is applicable to floor and countertop model gas and electric units.

1.3 The water-bath rethermalizer can be evaluated with respect to the following (where applicable):

1.3.1 Energy input rate (10.2),

1.3.2 Preheat energy consumption, time, and rate (10.4),

1.3.3 Idle energy rate (10.5),

1.3.4 Pilot energy rate (10.6),

1.3.5 Retherm energy rate (10.8),

1.3.6 Production capacity (10.8), and

1.3.7 Retherm-energy efficiency (10.8).

1.4 This test method is not intended to answer all performance criteria in the evaluation and selection of a water-bath rethermalizer.

1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Significance and Use

5.1 The energy input rate test is used to confirm that the water-bath rethermalizer under test is operating in accordance with its nameplate rating.

5.2 The water-bath rethermalizer temperature calibration is used to ensure that the water-bath rethermalizer being tested is operating at the specified temperature. Temperature calibration also can be used to evaluate and calibrate the thermostat control dial(s).

5.3 Preheat energy and time can be useful to food service operators to manage energy demands, and to estimate the amount of time required for preheating a water-bath rethermalizer.

5.4 Idle energy rate and pilot energy rate can be used to estimate energy consumption during non-rethermalizing periods.

5.5 Production capacity is used by food service operators to choose a water-bath rethermalizer that matches their particular food output requirements.

5.6 Retherm-energy efficiency is a precise indicator of the water bath rethermalizer’s energy performance under full-load condition. This information enables the operator to consider energy performance when selecting a water-bath rethermalizer.
