基于GB/T17713-2022标准吸油烟机声功率级测量不确定度评定

Evaluation of Uncertainty in Measuring the Sound Power Level of Range Hoods Based on GB/T 17713-2022 Standard

本文主要阐述依据GB/T17713-2022《吸油烟机及其他烹饪烟气吸排装置》标准测试声功率级的过程,并对吸油烟机声功率级测量不确定度进行了评定,通过不确定度的A类评定和B类评定方法分析评估出各个不确定分量的值,并最终计算得出本次吸烟机声功率级测量扩展不确定度值。

This article mainly elaborates on the process of measuring the sound power level of range hoods based on the standard GB/T 17713-2022"Range hoods and other cooking smoke suction and exhaust devices".The uncertainty of measuring the sound power level of range hoods is evaluated,and the values of each uncertain component are analyzed and evaluated through the Type A and Type B evaluation methods of uncertainty.Finally,the extended uncertainty value of measuring the sound power level of this range hood is calculated.
