1.1 本试验方法评估抽屉加热器的预热、闲置和保温能耗以及温度均匀性。餐饮服务运营商可以使用此评估来选择抽屉加热器，并了解其能量性能和温度均匀性。抽屉取暖器是一种商用厨房用具，由一个或多个加热抽屉组成，用于盛放在指定温度下在单独器具中烹饪的热食物（通常不超过200°F）。 1.2 本试验方法适用于配备有以下装置的独立式和内置式电动抽屉加热器: 1.2.1 行业标准12 × 20 × 6–英寸。（标称尺寸）平底锅，或 1.2.2 标准加大尺寸15 × 20 × 5–英寸。（标称尺寸）平底锅。 1.3 抽屉加热器可根据以下方面进行评估（如适用）: 1.3.1 能量输入率( 10.2 ), 1.3.2 最大设置时的能耗率( 10.2 ), 1.3.3 温度校准( 10.3 ), 1.3.4 预热能耗和时间( 10.4 ), 1.3.5 空闲能量率( 10.5 ), 1.3.6 保持能量率( 10.6 )，和 1.3.7 温度均匀性( 10.6 ). 1.4 以英寸-磅为单位的数值应视为标准值。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 能量输入率和恒温器校准测试用于在进一步测试之前确认抽屉加热器工作正常。 5.2 预热能量和时间有助于食品服务运营商管理能源需求，并了解抽屉加热器的运行速度。 5.3 餐饮服务运营商可以使用空闲能量率和保持能量率来估计运营期间的能耗，并在选择抽屉取暖器时考虑能耗。 5.4 操作员可以使用抽屉盘温度和抽屉盘温度均匀性来选择满足其食物存放需求的抽屉加热器。

1.1 This test method evaluates the preheat, idle, and holding energy consumption and temperature uniformity of drawer warmers. The food service operator can use this evaluation to select a drawer warmer and understand its energy performance and temperature uniformity. A drawer warmer is described as a commercial kitchen appliance that consists of one or more heated drawers and which is used to hold hot food (usually no greater than 200°F) that has been cooked in a separate appliance, at a specified temperature. 1.2 This test method is applicable to freestanding and built-in electric drawer warmers equipped for: 1.2.1 Industry-standard 12 × 20 × 6–in. (nominal size) pans, or 1.2.2 Standard-oversized 15 × 20 × 5–in. (nominal size) pans. 1.3 The drawer warmer can be evaluated with respect to the following (where applicable): 1.3.1 Energy input rate ( 10.2 ), 1.3.2 Energy consumption rate at maximum setting ( 10.2 ), 1.3.3 Temperature calibration ( 10.3 ), 1.3.4 Preheat energy consumption and time ( 10.4 ), 1.3.5 Idle energy rate ( 10.5 ), 1.3.6 Holding energy rate ( 10.6 ), and 1.3.7 Temperature uniformity ( 10.6 ). 1.4 The values stated in inch-pound units are to be regarded as 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. ====== Significance And Use ====== 5.1 The energy input rate and thermostat calibration tests are used to confirm that the drawer warmer is operating properly prior to further testing. 5.2 Preheat energy and time can be useful to food service operators to manage energy demands and to know how quickly the drawer warmer can be ready for operation. 5.3 Idle energy rate and holding energy rate can be used by the food service operator to estimate energy consumption during operating periods and to consider energy consumption when choosing a drawer warmer. 5.4 The drawer pan temperature and drawer pan temperature uniformity can be used by an operator to choose a drawer warmer which meets their food holding needs.
