Compared with JJF 1261.5-2017, except for editorial modifications, the main changes of this specification are as follows. ---The name of the specification was changed from "Measurement and Detection Rules for Energy Efficiency of Automatic Rice Cookers" to "Measurement of Energy Efficiency of Electric Rice Cookers" Detection Rules"; --- Products whose heating method is electromagnetic induction heating have been added to the scope; ---In the term definition, change "standby energy consumption of automatic rice cooker" to "standby power" (see 3.2,.2017 edition 3.2); --- Added the terms and definitions of "thermal efficiency" (see 3.4); --- Improved thermal efficiency, heat preservation energy consumption and standby power indicators (see 5.2, 5.2 of the.2017 edition); ---The products of 600W~1000W are merged into one power section from the original two power sections (see 5.2, 5.2 of the.2017 edition); --- The measuring equipment has added a digital thermometer with a platinum resistance probe (see 6.2.1.1); --- Changed the requirements for the extended uncertainty of standby power (see 6.3.2, 6.3.2 of the.2017 edition); ---In the thermal efficiency calculation formula, a certain supplement is given to the energy efficiency of electromagnetic induction heating and non-metallic inner pot products compensation (see 7.2.2.1, 7.2.2.1 of the.2017 edition); ---In the test method, the maximum temperature measurement method for thermal efficiency measurement has changed (see 7.2.2.1,.2017 version 7.2.2.1); --- In the test method, the insulation temperature requirement has changed (see 7.2.2.3,.2017 edition 7.2.2.3). The previous releases of this specification are as follows. JJF 1261.5-2017; JJF 1261.5-2012. Measuring and testing rules for energy efficiency of rice cookers1 ScopeThis specification stipulates that working under normal pressure, heating by electric heating elements or electromagnetic induction, the rated power shall not exceed Measuring requirements, measuring and testing procedures, measuring and testing methods, and measuring and testing results of energy efficiency of.2000W electric rice cookers Evaluation criteria and test reports, etc. This specification is applicable to the supervision and inspection of the energy efficiency measurement of rice cookers, and entrusted testing can refer to this specification. production and Units that sell rice cookers can also conduct testing with reference to this specification. The rice cooker to be tested should be a product that has passed the self-inspection of the producer, or a product imported and sold by the seller.2 ReferencesThis specification references the following documents. JJF 1261.1-2017 Energy Efficiency Measurement and Testing Rules for Energy-Using Products GB/T 2829-2002 Sampling procedure and table for periodic inspection counting (applicable to inspection of process stability) GB 12021.6-2017 Allowable values of energy efficiency and energy efficiency grades for electric rice cookers For dated references, only the dated version applies to this specification; for undated references document, its latest version (including all amendments) applies to this specification.3 Terminology and units of measurementThe following terms and units of measurement apply to this specification. Under the premise of meeting the requirements of heat preservation energy consumption and standby power, the minimum allowable value of the rice cooker under the test conditions specified in the standard Xu thermal efficiency. 3.2 standby power standbypower When the rice cooker is connected to the power supply and is in the waiting state (the electric heating element or the induction coil is not heating) Rate. The unit of measurement is watts (W). Electricity consumption per hour when the rice cooker enters the keep warm state. The unit of measurement is watt-hour (W·h). 3.4 thermal efficiency heatefficiency The ratio of the effective output energy of an electric rice cooker to the input energy.4 OverviewElectric rice cooker is a product that implements energy efficiency label management. It uses electric energy to heat and can automatically control the cooking in the pot. Temperature, mainly used for electric cooking appliances for cooking rice. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJF 1261.5-2022_English be delivered?Answer: Upon your order, we will start to translate JJF 1261.5-2022_English as soon as possible, and keep you informed of the progress.
