摘　　要：制热水能力是饮水机产品的一项重要的性能指标,也是消费者选购饮水机时的主要关注点之一。但部分生产单位在标注该参数值时,未基于多次重复测试的数据结果或未评估测试结果的不确定度,导致产品存在虚标的情况,市场抽检中被判定不合格。本文以某一款饮水机为例,对其制热水能力的测试方法和计算过程进行了详细概述,分析了影响测试结果准确性的因素,并对测试结果的不确定度进行了评估和探讨,旨在指导相关生产单位合理标注参数值,避免抽检不合格的风险。Water-heating capacity is an important performance parameter of water dispensers,and it is also one of the major concerns of consumers when purchasing water dispensers.However,when marking this parameter value,some manufacturers did not use values based on repeated test results or did not evaluate the uncertainty of test results,which resulted in inaccurate labeling,with products determined as unqualified in market sampling.Taking a certain water dispenser as an example,this paper gives a detailed overview of the test method and calculation process of water-heating capacity,analyzes the factors that affect the result accuracy,and evaluates and discusses the uncertainty of test results,aiming to guide the relevant manufacturers to mark the parameter values reasonably and avoid the risk of unqualified sampling.
