Significance and Use
5.1 The energy input rate test and thermostat calibration are used to confirm that the conveyor oven is operating properly prior to further testing and to insure that all test results are determined at the same temperature.
5.2 Preheat energy and time can be useful to food service operators to manage power demands and to know how quickly the conveyor oven can be ready for operation.
5.3 Idle Energy Rate—This test provides a measure of an empty oven’s energy consumption and pilot energy during noncooking periods, at a typical cooking temperature setting. It also provides an indicator of the combined effectiveness of components of the oven’s design (for example, insulation, door seals, and combustion efficiency) that influence its energy consumption.
5.4 Cooking Energy Efficiency—A precise indicator of conveyor oven energy performance while cooking a typical food product under various loading conditions. If energy performance information is desired using a food product other than the specified test food, the test method could be adapted and applied. Energy performance information allows an end user to better understand the operating characteristics of a conveyor oven.
5.5 Production capacity information can help an end user to better understand the production capabilities of a conveyor oven as it is used to cook a typical food product and this could help in specifying the proper size and quantity of equipment. If production information is desired using a food product other than the specified test food, the test method could be adapted and applied.
1.1 This test method covers an evaluation of the energy consumption and cooking performance of conveyor ovens. The food service operator can use this evaluation to select a conveyor oven and understand its energy consumption.
1.2 This test method is applicable to gas and electric conveyor ovens.
1.3 The conveyor oven can be evaluated with respect to the following (where applicable):
1.3.1 Energy input rate and thermostat calibration (see ),
1.3.2 Preheat energy consumption and time (see ),
1.3.3 Idle energy rate (see ),
1.3.4 Pilot energy rate (if applicable) (see ), and
1.3.5 Cooking energy efficiency and production capacity (see ).
1.4 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This test method may involve hazardous materials, operations, and equipment. 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.
1.6 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.
