5.1 The maximum energy input rate test is used to confirm that the dishwasher is operating at the manufacturer's rated input prior to further testing. This test method also will indicate any problems with the electric power supply, gas service pressure, or steam supply flow or pressure.5.2 Tank and booster temperatures, as well as water consumption, are adjusted to NSF specifications to insure that the test is applied to a properly functioning dishwasher.5.3 Because much of a dishwasher's operating period is spent in the idle condition, tank heater and booster idle energy consumption rate(s) are important parts of predicting dishwasher's energy consumption.5.4 The washing energy performance test determines energy usage per rack. This is useful both as a measure for comparing the energy performance of one dishwasher to another and as a predictor of the dishwasher’s energy consumption.5.5 Water-consumption characterization is useful for estimating water and sewage costs associated with dishwashing machine operation.1.1 This test method evaluates the energy and water consumption of rack conveyor, commercial dishwashing machines, hereafter referred to as dishwashers. Dishwashers may have remote or self-contained booster heater. This procedure does not address cleaning or sanitizing performance.1.2 This test method is applicable to both hot water sanitizing and chemical sanitizing rack conveyor machines, which include both single tank and multiple tank machines. Rackless conveyors (i.e. flight type machines) are included. Dishwasher tank heaters are evaluated separately from the booster heater. Machines designed to be interchangeable in the field from high temp and low temp (i.e. Dual Sanitizing Machines) and vice versa, shall be tested at both settings. Machines should be set for factory settings. If a dishwasher includes a prewash tank heater as an option, energy should be submetered separately for the prewash tank heater. This test method may be used for dishwashers with steam coil tank or booster heat, but not dishwashers with steam injection tank or booster heat. When the test method specifies to use the data plate or manufacturer’s recommendations, instructions, specifications, or requirements, the information source shall be used in the following order of preference and documented in the test report: data plate, user manual, communication with manufacturer.1.3 The following procedures are included in this test method:1.3.1 Procedures to Confirm Dishwasher is Operating Properly Prior to Performance Testing: 1.3.1.1 Maximum energy input rate of the tank heaters (10.5).1.3.1.2 Maximum energy input rate of the booster heater, if applicable (10.6).1.3.1.3 Final sanitizing rinse water consumption calibration (10.7).1.3.1.4 Booster temperature calibration, if applicable (10.2).1.3.1.5 Wash tank temperature calibration (10.3).1.3.1.6 Wash tank pump and conveyor motor calibration (10.4).1.3.2 Energy Usage and Cycle Rate Performance Tests: 1.3.2.1 Washing energy performance test (10.8).1.3.2.2 Tank heater idle energy rate (10.9).1.3.2.3 Booster idle energy rate, if provided (10.10).1.4 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.1.5 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.

5.1 The energy input rate test is used to confirm that the conveyor broiler is operating properly prior to further testing.5.2 Preheat energy and time can be useful to food service operators to manage power demands and to know how quickly the conveyor broiler can be ready for operation.5.3 Idle energy rate and pilot energy rate can be used to estimate energy consumption during non-cooking periods.5.4 Temperature uniformity of the broiler cavity may be used by food service operators to understand the heat distribution throughout the broiler cavity and select a conveyor broiler that matches their required temperature characteristics.5.5 Cooking energy efficiency is a precise indicator of conveyor broiler 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 broiler.5.6 Cooking uniformity of the broiler may be used by food service operates to select a conveyor broiler that provides a uniformly cooked product.5.7 Production capacity information can help an end user to better understand the production capabilities of a conveyor broiler 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 evaluates the energy consumption and cooking performance of conveyor broilers. The food service operator can use this evaluation to select a conveyor broiler and understand its energy consumption.1.2 This test method is applicable to gas, electric, and hybrid gas/electric conveyorized broilers. This test method covers both units with continuously operating conveyors and batch-style units with intermittently operating conveyors.1.3 The conveyor broiler can be evaluated with respect to the following (where applicable):1.3.1 Energy input rate (see 10.2),1.3.2 Preheat energy consumption and time (see 10.3),1.3.3 Idle energy rate and temperature uniformity (see 10.4),1.3.4 Pilot energy rate (if applicable) (see 10.5), and1.3.5 Cooking energy efficiency, cooking uniformity and production capacity (see 10.8 and 10.9).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 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.
