吸油烟机噪声测试标准差异的对比分析

Comparison and Analysis of the Differences of Range Hood Noise Test Standards

GB/T 4214.13—2021《家用和类似用途电器噪声测试方法吸油烟机及其他烹饪烟气吸排装置的特殊要求》于2022年3月正式实施,与标准GB/T 17713—2011《吸油烟机》相比,GB/T 4214.13—2021在吸油烟机的噪声测试方面作了较大的改动。从试验环境、预处理、安装方法、传声器的布置及测量表面、声压级和声功率级的计算等维度对两个标准的差异进行对比分析,并开展对比测试,可帮助标准使用人员快速理解和熟悉两个标准间的差异,了解测试方法变化对测试结果的影响。

GB/T 4214.13—2021“Test method for noise of household and similar electrical appliances-particular requirements for range hoods and other cooking fume extractors devices”was officially implemented in March 2022.Compared with GB/T 17713—2011“Range hood”,GB/T 4214.13—2021 has made major changes in the noise test of range hood.Comparative analysis of the differences between the two standards is carried out from the dimensions of test environment,pretreatment,installation method,microphone layout,measurement surface,sound pressure level and sound power level calculation,and comparative tests are carried out,which can help standard users quickly get familiar with the differences between the two standards and understand the impact of test method changes on test results.
