室内加热器输入功率偏差数据

室内加热器是一种用于提供加热室内环境的家用电器。输入功率是室内加热器一项重要的评价指标。若实际输入功率低于铭牌明示的额定输入功率，说明产品存在虚标的问题，其功能可能达不到使用者预期的效果；若实际输入功率远高于铭牌明示的额定输入功率，使用者会误选插座和电线，极端情况有可能导致过热起燃，造成危险。通过测试抽检的市售室内加热器，将输入功率实测值与明示额定输入功率值、标准要求偏差值进行比对分析，有助于对市售室内加热器现状的风险评估与分析，为政府监管、消费者购买提供参考和技术支撑。"1、数据采集：随机选取市售室内加热器产品，对样品的额定输入功率进行记录；
2、数据检测：依据最新版国标GB4706.1《家用和类似用途电器的安全 第1部分:通用要求》和GB4706.23《家用和类似用途电器的安全 第2部分：室内加热器的特殊要求》对样品的输入功率进行测试，并记录实测输入功率；
3、数据判定：输入功率偏差=（实测输入功率-额定输入功率）/额定输入功率×100%，根据计算得出的输入功率偏差值与标准要求偏差值进行标准结果判定，并计算总体合格率；
4、数据应用：对市售室内加热器输入功率偏差值情况进行调查，从而为室内加热器安全性评估提供参考，也为此类产品火灾风险分析提供事实依据。"

Room heaters are household electrical appliances used to provide heating for indoor spaces. Input power is an important evaluation indicator for room heaters. If the actual input power is lower than the rated input power marked on the nameplate, the product has a false labeling problem, and its function may not meet the user's expected effect; if the actual input power is much higher than the rated input power marked on the nameplate, users may incorrectly select sockets and wiring, and in extreme cases, it may lead to overheating and ignition, causing dangers. By testing and spot-checking commercially available room heaters, and comparing and analyzing the measured input power values with the marked rated input power values and standard required deviation values, it is helpful for risk assessment and analysis of the current status of commercially available room heaters, providing reference and technical support for government supervision and consumer purchasing.
1. Data Collection: Randomly select commercially available room heater products, and record the rated input power of the samples;
2. Data Testing: Conduct tests on the input power of the samples in accordance with the latest versions of national standards GB4706.1 "Safety of household and similar electrical appliances - Part 1: General requirements" and GB4706.23 "Safety of household and similar electrical appliances - Part 2: Particular requirements for room heaters", and record the measured input power;
3. Data Judgment: Input power deviation = (measured input power - rated input power) / rated input power × 100%. Perform standard result judgment based on the calculated input power deviation value and the standard required deviation value, and calculate the overall qualified rate;
4. Data Application: Investigate the input power deviation status of commercially available room heaters, so as to provide reference for the safety assessment of room heaters, and also provide factual basis for the fire risk analysis of such products.
