1.1 本测试方法涵盖了对商业和机构设施中使用的商用咖啡冲泡机（以下简称咖啡冲泡机）的能耗、冲泡和保温性能的评估。操作员可以使用此评估来选择咖啡冲泡机，并描述其能源使用和性能。本试验方法不适用于住宅咖啡壶、“瓮”咖啡壶( 类型III )，或意式浓缩咖啡机。 1.2 本试验方法适用于单杯( I类 )和批次( 类型II )咖啡机。咖啡冲泡机将进行以下测试（如适用）: 1.2.1 最大能量输入速率， 1.2.2 大量使用酿造能耗， 1.2.3 生产能力， 1.2.4 “准备酿造”（待机/空闲）能量率，以及 1.2.5 “节能模式”（低功耗）能效。 1.3 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 5.1 测量的最大能量输入率用于确认咖啡冲泡机是否按照其铭牌额定值运行。 5.2 如果适用且可接近，则测量锅炉或内部水箱的温度，以确保水保持在准备冲泡的温度。这也可以在以后用于将咖啡冲泡机的能耗标准化到标准温度。 5.3 预热测试可用于测量咖啡冲泡机从环境室和进水温度达到准备冲泡状态所需的时间和能量。 5.4 “即煮即用”和“节能模式”的能量可供最终用户用于估算不冲泡咖啡时消耗的能量。 5.5 高能耗可用于估算咖啡冲泡机在冲泡咖啡时消耗了多少能量。除了预热和准备冲泡（待机）能量外，最终用户还可以使用该值来模拟他们的机器能量使用。 5.6 生产能力是通过测试确定的计算指标，用于定义咖啡冲泡机的性能。最终用户可以使用此值指定符合其生产需求的酿酒商。

1.1 This test method covers the evaluation of the energy consumption, brewing, and holding performance of commercial coffee brewing machines (here after referred to as coffee brewers) used in commercial and institutional facilities. The operator can use this evaluation to select a coffee brewer and characterize its energy use and performance. This test method does not cover residential coffee brewers, “urn” coffee brewers ( Type III ), or espresso machines. 1.2 This test method applies to single cup ( Type I ) and batch ( Type II ) coffee brewers. The coffee brewer will be tested for the following (where applicable): 1.2.1 Maximum energy input rate, 1.2.2 Heavy use brewing energy consumption, 1.2.3 Production capacity, 1.2.4 “Ready-to-Brew” (Standby/Idle) energy rate, and 1.2.5 “Energy Save Mode” (Low power) energy rate. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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 measured maximum energy input rate is used to confirm that the coffee brewer is operating in accordance with its nameplate rating. 5.2 If applicable and accessible, the boiler or internal tank temperature is measured to ensure that the water is maintained at a ready-to-brew temperature. This can also be used later to normalize coffee brewer energy consumption to a standard temperature. 5.3 The Preheat Test can be used to gauge the amount of time and energy required for the coffee brewer to reach a ready-to-brew state from the ambient room and incoming water temperatures. 5.4 Ready-to-Brew and Energy Save Mode energy can be used by end users to estimate the amount of energy consumed while coffee is not being brewed. 5.5 Heavy-use energy consumption can be used to estimate how much energy is consumed by the coffee brewer when brewing coffee. Along with preheat and ready-to-brew (standby) energy, this value can be used by end users to model their machine energy use. 5.6 Production capacity is a calculated measure, determined through testing, to define the performance of the coffee brewer. End users can use this value to specify a brewer that matches their production needs.
